PC/104 UPS and Universal Charger with Solar Panel Support

The V12SC-SER when integrated with a backup power source is a rugged uninterruptable power system (UPS) supplying up to 12V@ 5A and 5V@ 1A for use in remote and hostile environments. The V12SC-SER can be powered from a solar panel or from a vehicle power source. The input power protection is designed to MIL-STD-1275 requirements and can handle transients and load dumps found on heavy vehicles such as large mining trucks. 

The PC/104 footprint is easily integrated with other modules such as CPU, communication and I/O modules . The universal charger can handle NiCd, NiMh, SLA, Li-Ion, ultra capacitors and SMBus backup power sources. The V12SC-SER-UPS includes on-board NiMh batteries providing 6.3 watt-hr of backup energy. 

The V12SC-SER has two RS232 ports for data monitoring and control. One port has 2500Vrms isolation and includes 5V@ 200mA making it ideal for remote sensors for sunlight intensity and solar pnel temperature. The second port includes 5V@ 1A of power for devices such as a low power CPU. The 5V power on the serial ports are independently switchable to the 12V output. 

Three full color RGB LED indicators on the V12SC-SER provide operational status and an additional three off board RGB LED indicators can be used for remote status indication. The LEDs can be remotely controlled over the RS232 ports permitting indication of other functions.
