6-30V Intelligent Uninterruptible Power Supply

Installation Guide

Version 1.0f
P/N OPENUPS-06
Before you start...
Please take a moment and read this manual before you install the OPENUPS.
Often times, rushing into installing the unit can result in serious damage to your OPENUPS
board, computer. Always double check the polarity of your wires with a voltmeter.
Introduction
Thank you for purchasing the OPENUPS Uninterruptible power supply.
The OPENUPS was designed to provide user specified regulated power output from a wide
input voltage, battery backup, multi-chemistry charging and cell balancing in a single PCBA.
OpenUPS features include:
-USB interface, works with Windows devices (Linux API planned)
-SMBUS slave and I2C master
-Input between 6-30V
-Programmable voltage thresholds,
-Generate any output voltage between 6-24V,
-Supports multiple battery chemistry
-Balances up to 6 series batteries.
-Charge voltage between 6-30V, charge current up to 3A, battery balancing up to 6 cells,
-Coulomb counting (fuel gauge)
-Motherboard ON/OFF pulse control*

    OPENUPS 6-30V Intelligent Uninterruptible Power Supply Installation Guide Version 1.0f P/N OPENUPS-06 Before you start… Please take a moment and read this manual before you install the OPENUPS. Often times, rushing into installing the unit can result in serious damage to your OPENUPS board, computer.
  • Page 2 -Windows detects device as “Battery”, no special drivers required ** *MotherBoard ON/OFF control: The device is able to send ON/OFF 'pulse signals' to motherboard based on coulomb counter and/or battery voltage level, or based on input voltage level or when starting. **Windows “no driver support”: Installs itself as a battery in Windows, using the Windows hid driver without any driver installation, visible as an icon in tray bar.
  • Page 3 Bootloader Mode The device can start in bootloader mode so firmware updates are possible without using the programming header. Place a jumper between J2.4 and J2.5, than connect the unit to USB to enter bootloader mode. Start the HIDBootLoader.exe software provided to flash the new firmware. Reseting the MCU Placing shortly a jumper between J2.1 and J2.2 will reset the internal MCU reloading your reconfigured parameters and restarting the UPS.
  • Page 4 to connect anywhere) - connect cell_5 to position 5 on J6 header - connect cell_4 to position 4 on J6 header - connect cell_3 to position 3 on J6 header - connect the battery's negative terminal(or GND) to position 2 on J6 header Starting and Stopping with battery power….

  • Page 8 Default is 5 sec. UPS_HARDOFF_TOUT[s] After UPS_VBAT_UVP_OFF_TOUT passed motherboard is signaled to shut down. The UPS will wait this period so that the Motherboard can shut down gracefully, than cut power and enter deep sleep. This period should not be too long to prevent battery drain.
  • Page 9 voltage/cell during constant current/constant voltage charging Default is 14.1V CHG_HYSTERESIS[V/cell] An over-voltage value (CHG_BULK_STOP_VOLTAGE +CHG_HYSTERESIS ) that it is allowed when charging. If one of the cells exceeds this value charging is immediately stopped. Default is 100mV/cell. CHG_START_VOLTAGE [V/cell] If cell voltage is below this value charging can be started.
  • Page 10 Default is 1pcs. BAL_VCELL_MIN[V] Balancing is allowed if cell voltages are above this value. Default is 3V BAL_VCELL_DIFF_START [V] If the voltage difference between cells exceeds this value start balancing the cells. Default is 70mV. BAL_VCELL_DIFF_STOP[V] If the voltage difference between cells is less than this value stop balancing the cells.
