Tri-M HPSC104-SER - 160W Rugged Smart PC/104 Vehicle Power Supply

5V, 12V & -5VSB Outputs Standard, -40 to +85 Operation


The HPSC104-SER is a DC-DC converter that includes a flash based microcontroller and 4 amp charger for advanced power management and smart battery charging. Combined with a Tri-M standard battery pack or super cap module, the HPSC104-SER can be used as an Uninterruptible Power Source (UPS) for a PC/104 system. The HPSC104-SER is designed for low noise embedded computer systems, has a wide input range of 6 to 40 V DC and is ideal for battery or unregulated input applications.

The HPSC104-SER provides up to four stages of battery charging and can charge SLA, NiCd, and NiMh batteries and level two and three SMBus compatible batteries. Charge currents are up to 4A, and battery charging voltages from 10V to 35V DC. The HPSC104-SER has advanced power management functions that allows timed on/off control of the unit, notification of changes to main power and changes in the battery status. For example, the HPSC104-SER can be programmed to power off the main outputs in 60 seconds and then turn them on again 12 hours later. In addition to smart charging and power management the HPSC104-SER can monitor up to 16 different temperatures using digital I²C digital temp sensors. The HPSC104-SER is available as RoHS, is PC/104 compliant and rugged enough for to meet the demands on military and mining vehicle power supplies, including -40°C to +85°C extended temperature rating.
