6-38V Intelligent Automotive grade Uninterruptible Power Supply
Before you start…
Often times, rushing into installing the unit can result in serious damage to your DCDC-NUC UPS board or computer. Always double check the polarity of your wires with a voltmeter.
Always double check the polarity of the batteries before introducing into the UPS device.
Improper configuration leads to system damage!!!
* NOTE: Forced ventilation or 40% input or output current de-rating or both is required if any of the following conditions are met:
If V(IN) 24-38V
If I(Out) > 2A and T(ambient) > 30°C, open air operation.
In order to prevent premature battery damage due to thermal exposure, always check NUC-UPS board temp and ensure it does not exceed 55C for your application.
The NUC-UPS was designed to provide +12V regulated power output from a wide input voltage(6V-38V).
It has a range of intelligent functions not found in any of the traditional USB converters.
The unit is able to gracefully shut down motherboards based on Ignition sensing or battery voltage level, by pulsing
the motherboard on/off pins. This makes it an ideal device for automotive or battery powered installations.
It features 4 replaceable Li-Ion batteries for battery backup integrated in the device, there is no need for any
kind of special cabling between cells and UPS. The charger is a Synchronous Buck-Boost converter capable of charging the batteries with input voltage below, equal
or above battery voltage level.
It charges the battery in three phases: preconditioning, constant current mode and constant voltage mode.
The output converter is a synchronous Buck converter providing regulated 12V output. The unit can be used as an embedded UPS or as a Portable Energy Pack providing the user with regulated 12V wherever

- - press F2 key during the boot sequence to entering the NUC's BIOS (Visual BIOS 2.0)
- - first click on Advanced then click on Power menu button
- - in Secondary Power Settings section select Power On option for After Power Failure
- - the picture shows the right option in a red framework
- - now the power supply should be able to START the NUC by applying corresponding voltage to its power
It is recommended that you only connect USB power to the device when making a firmware update via “bootloader mode”.
There are two ways to enter in bootloader mode: 1a) or 1b).
1a) Place a jumper on the P8.4 and P8.5 pins then connect the unit to USB
1b) Connect the unit to USB then press the Switch to bootloader button on the configuration software's user
2) Start the HIDBootloader v2.9j.exe software
provided to flash the new firmware.
3) Press File->Import Firmware Image
4) Press Open new Hex File
5) Press Program->Erase/Program/Verify Device
6) If used option 1a) remove the jumper 6) Press Program->Reset Device
7) After the device reconnects on USB with the configuration software the new firmware version will be displayed in
the title bar of the software.
NUC-UPS operating modes
For configuration purposes only the unit can be started by connecting the unit to USB.
Inserting the batteries should be the first step to perform.
Waking the unit for the first time implies applying input voltage.
The operating modes can be selected by setting the NUC_UPS_MODE parameter to 0(DUMB mode) or 1(AUTOMOTIVE mode).
Further parameters can be customized by changing in the Parameter List.
- When in this mode the unit still works as an UPS or it can be used as a general purpose battery pack.
- Starting the unit
- In this mode starting can be performed either by applying input voltage or pressing the button for 500ms.
- Stopping the unit
- In this mode stop sequence can be initiated by pressing the button for 500ms.
- Starting the unit
- In this mode Starting can be performed by applying input voltage and applying ignition voltage.
- The ignition voltage thresholds are configurable set by the IGN_HIGH_THRESHOLD, IGN_LOW_THRESHOLD parameters.The
Ignition voltage must be higher than IGN_HIGH_THRESHOLD for the duration set by the IGN_COUNT parameter in order to
filter out unwanted noise in automotive environment.
- Stopping the unit
- In this mode stop sequence can be initiated if Ignition voltage is lower than IGN_LOW_THRESHOLD parameter for the
duration set by the IGN_COUNT parameter.
Stop conditions that apply in both modes
- When the unit is running on batteries the following conditions can initiate shutdown(the shutdown reason can be
identified on the Status-UPS tab,Shutdown groupbox in the Configuration software):
- -one of the cell voltages is less than UPS_VCELL_MIN_STOP parameter, shutdown sequence is initiated.
- -the unit is on battery for more than UPS_ON_BATTERY_TOUT parameter, shutdown sequence is initiated.
- -one of the cell voltages is less than UPS_VCELL_MIN_HARD_STOP parameter, shutdown is immediate.
- -one of the batteries temperature is out of the limits set by the DCHG_TEMP_COLD, DCHG_TEMP_HOT parameters.
- -overload, when the maximum allowed discharge current exceeds the value set by UPS_OVERLOAD parameter.
- If output is out of regulation the unit is immediately stopped.
Startup and Shutdown sequence
The following options are available to control the motherboard by pulsing the on/off pins on the motherboard.
First the the motherboard On/OFF pins should be connected to the P5.1,P5.3 pin on the P5 Interface_connector.
The pulse width is 500ms by default which can be altered by changing MOB_PULSEWIDTH parameter from the Parameter_List.
There are various ways to control the motherboard depending the configuration of the CONFIG1 register from the Parameter_List.
Example:If startup of the motherboard is not needed when input is present, the startup pulse can be disabled by setting CONFIG1.b0 to 0.
The same way the shutdown pulse can be inhibited by setting CONFIG1.b1 to 0.
There are cases when motherboard started(ON) or OFF presence must be detected in order starting/stopping by pulses behavior work properly.
For example the Operating System could be shutdown already from software. In case the unit is is a shutdown sequence not knowing this piece of information would lead by sending the shutdown pulse which would wake up instead the system.
There are two kinds of feedback information to detect motherboard status.
The first detection mode is by measuring the consumed output power, knowing that a motherboard when started consumes much more power than when in standby.
In order to enable this feature the following steps should be performed:
1. Enable this feature, CONFIG1.b2 should be set to 1.
2. Observe and note the consumption of the connected motherboard when in standby and when is ON. Our unit measures the output power(POUT) which is displayed in the configuration software.
3. Set POUT_HIGH_THRESHOLD and POUT_LOW_THRESHOLD parameters from the Parameter_List accordingly with a good margin.
POUT<POUT_LOW_THRESHOLD motherboard is considered OFF.
POUT>POUT_HIGH_THRESHOLD motherboard is considered ON.
The second detection mode is by measuring the +5VUSB signal. Usually motherboards turn OFF the +5VUSB signal when they are OFF.
In order to enable this feature CONFIG1.b3 must be set to 1.
The charger is a Synchronous Buck-Boost converter capable of charging the batteries with an input voltage below, equal or above battery voltage level.
The charging happens three phases: preconditioning, constant current mode and constant voltage mode:
- • The charging is starting with a preconditioning phase, where the current is limited to ~350mA. The preconditioning phase has a minimum duration set by CHG_COND_TOUT which is extended if one of the cells voltage is below the limit set by CHG_CELL_VCOND.
- • In constant current phase charge current is limited to 1A. After battery voltage rises to the value set by the hardware charger, the charger will enter constant voltage mode.
- • In constant voltage phase the battery will absorb less current as time passes and charge current will decrease. When the charge current decreases below ~150mA, charging is stopped.
During low power state the charger is disabled, so the charger module is also disabled in automotive mode when the Ignition is OFF, even if input is present.
Charging will be terminated if a global charge timer elapses, this can be set by CHG_GLOBAL_TOUT parameter.
Charging is limited to precharge value if one of the batteries temperature exceeds limits set by CHG_TEMP_COOL,CHG_TEMP_WARM parameters.
Charging is terminated if one of the batteries temperature exceeds the limits set by CHG_TEMP_COLD,CHG_TEMP_HOT.
In order to work properly the following conditions when changing parameters must be fulfilled: CHG_TEMP_COLD < CHG_TEMP_COOL < CHG_TEMP_WARM < CHG_TEMP_HOT.
The temperature sensors are located just below the batteries for proper temperature detection of each cell.
NUC-UPS Charge Balancer
The balancing algorithm is voltage based. Balancing is allowed if cell voltage exceeds the value set in the BAL_VCELL_MIN parameter.
Balancing is started if the voltage difference between the cells is higher than BAL_VCELL_DIFF_START, and will be stopped if the difference is lower than the value defined in BAL_VCELL_DIFF_STOP parameter.
NUC-UPS Fuel gauge
The initial remaining capacity is detected based on an open-circuit voltage based state-of-charge estimation, using the predefined values set by the OCV_SOCxx parameters.
Further estimation is based on coulomb counting method which is more precise after a full charge cycle has been performed.
The unit has two LEDs on board (Red and Green), located on the right and left side of the USB connector.
While there are scenarios where both LEDs are blinking with a certain pattern, the LEDs generally help identifying the power source that runs the UPS output at any given moment.
- • The green LED signals that the NUC-UPS is running from input voltage
- • The red LED signals that the NUC-UPS is running from batteries
The blinking patterns that can occur during operation are shown in the images below. The duration of LED blinks can also be seen on the images, displayed in milliseconds.

Windows OS built-in support
The NUC-UPS implements two generic USB classes, therefore most of the operating systems are recognizing it without
any additional driver installation. This two classes are:
a.) "HID UPS Battery" for OS built-in communication.
Microsoft Windows versions are recognizing this class automatically and the device should appear in device manager
at Batteries as a "Hid ups battery", together with all settings and power plan possibilities provided by the OS for
b.) "HID" for communication and configuration
This endpoint is a generic HID and it is used by our configuration and monitor software to read/write voltages and
other important parameters of the NUC-UPS. This endpoint does not needs any additional driver either, Microsoft
Windows OS should recognize it as a generic HID USB device.
The configuration software provides interface for NUC-UPS monitoring, logging and setup. It's recommended to be used by users with deeper understanding of the NUC-UPS hardware since permits setting
voltages, currents and other parameters which can be
dangerous if they are set without precaution.
The configuration software has three main screens (Status-UPS, Status-Charger and Settings) and a header with the
important voltage/current values.
The first main screen is the "Status-UPS"
Example of this screen is shown in the next image:
The title bar shows the connection status, the firmware version and the mode of the NUC-UPS. Example: "NUC-UPS
Connected v1.0 Mode: Dumb"
The header of the status screen contains:
- VIn: Input Voltage
- VIgn: Ignition Voltage
- VBat: Battery Voltage
- VOut: Output Voltage
- POut: Output Power
- IOut: Output Current
- Battery pack %: Battery percentage
- : Battery 0 status
- : Battery 1 status
- : Battery 2 status
- : Battery 3 status
- [Pack]: Battery pack overall voltage and current
The "Status-UPS" screen contains extended information about the current state of the NUC-UPS like internal state
machine, voltages, currents, temperature, different read only state flags. The user also have the possibility to log the current state into a *.csv file in the "Log" section.
The second main screen is the "Status-Charger"
Contains extended information about current state of the NUC-UPS battery charger (internal state machines, flags)
The third main screen is the "Settings"
Example of this screen is shown in the next image:
This screen contains two main sections: the individual parameter setup for experienced users and the parameter
save/load into/from file section.
The main section of the "Settings" screen is the individual parameter settings.
This is recommended to be done only by experienced users. Any parameter of the NUC-UPS can be set from here.
Changing one parameter is simple:
- - select the desired parameter from the "Parameter" list (simple click to select, double-click to edit). Below the
parameter list a helper text is displayed (same from this manual).
- - after double click introduce the new value in the new popup dialog and press OK
- - the introduced value is checked - if something is wrong (out of limit, bad value etc.) error message will be
- - the ! sign will blink on the "Sync all parameters to the NUC-UPS" button to show edited but not saved/synced
- - after You have done with all parameter setting press the "Sync all parameters to the NUC-UPS" button to send all
values to the NUC-UPS. IMPORTANT: without this step the new values will be lost, nothing is sent to the NUC-UPS!
IMPORTANT: any parameter setting is taken into account by the NUC-UPS in this cases:
- - after a full restart either with power cut from all sources (usb, vin)
- - hitting the "Restart NUC-UPS" button
- - keeping the "Reload parameters on the fly after sync" checked.
Do any parameter change with precaution, check the parameters and wires before applying it!
For users who need to setup more devices with the same NUC-UPS settings, it is recommended to use the save/load
parameters buttons. The "Parameters: NUC-UPS ===> File (settings.ini)" button loads a full configuration from the NUC-UPS and saves it
to the settings.ini file. You can disconnect the current NUC-UPS from the USB and insert a new one, than press the "Parameters: NUC-UPS <=== File (settings.ini)"
button to send the last saved configuration into the new NUC-UPS.
The "Parameters: NUC-UPS ===> CSV File (settings.csv)" button loads all parameters from the connected NUC-UPS and
saves it into a csv file. This type of file can be opened by any spreadsheet editor (OpenOffice, Microsoft Excel
etc.) and contains the full set of parameters in human readable form.
The "Switch to bootloader" button is intended to be used for firmware updates. After You press this button the NUC-
UPS will disconnect, it will switch to bootloader mode and firmware can be updated as described [[NUC-
Every save/load/sync operation on the "Settings" screen affects the progress bar and the status bar on the bottom of
the screen (labelled with "State:"). In rare cases You might get error here with "try again" message. This happens in case of one parameter byte get's corrupted or timeout
occurs during USB communication and/or NUC-UPS flashing operation. Please try again and contact our support team only if the device gives this error 4-5 times in a row.
Windows System monitor
The system monitor is a tray bar software which shows the current state on the tray bar icon and a semi transparent
"always on top" capable small window.
The popup window can be moved anywhere on the screen and can be customized. Our current setup has two skins but any
combination is possible playing with the "skin*.mbs" files installed together with this application. The current skin can be selected right clicking on the
The "skin*.mbs" files are simple text ones editable with any text editor (notepad for example).
Adding a new skin is pretty simple – make a skin1.mbs (use the existing skin0.mbs for starting content) and start
playing with the values from the new
The values are self explanatory – skin name, background image files, font descriptions and label/value pair
coordinates for all the important NUC-UPS values. The size of the popup is defined by the background image – transparent parts can be defined as well (see for
Right clicking on the tray icon will pop-up a simple menu:
From which You can see firmware version and state of the NUC-UPS from the NUC-UPS Properties and set some visual
parameters of the application (transparency, skin) from Skin:
For auto start with the system make a shortcut of AppTray.exe from the standalone package in the system Startup
