Battery Backup Module for HESC, V5SC & HPSC Series Power Supplies

Introduction
The BAT-NiMh45 creates a UPS system by plugging directly into the bottom of the Tri-M Engineering HESC, V5SC-SER or HPSC Power Supply. Each BAT-NiMh45 includes seven 4.5Ahr “A” size batteries for a nominal backup voltage of 8.4 volts. The BAT-NiMh45 can therefore supply a total of 37.8 watt-hrs of backup power and supply backup power for up to sixty minutes for a 37.8 watt load.

The BAT-NiMh45 includes Mosfet transistors for preventing deep discharge occurrences during extended power outages. The Mosfet transistors electrically isolate the BAT-NiMh45 from the HESC whenever the BE output of the HESC is de-asserted (pulled to 5V).

When ordered with the Real Time Clock option, the BAT-NiMh45-RTC can “awaken” from Sleep Mode at a programmed start-up time. A momentary “dry” contact on CN3 can also override the Sleep Mode and awaken the BAT-NiMh45-RTC. Tri-M Power supplies supporting the HESC-UPS18 firmware can program and read the RTC on the BAT-NiMh45-RTC. Tri-M Power Supplies with HESC-UPS firmware can use the BAT-NiMh45 for a UPS system, but without RTC support. Refer to section “Configuration and Installation” for listing of compatible power supplies and firmware support.

The BAT-NiMh45 has both a thermal fuse and a current fuse for protection against overcharging, and shorts on the battery output.

A digital I2C temperature sensor provides temperature feedback for charge termination, which can be read by the HESC.

Features and Benefits:
- Capacity 4500 ma-hr @ 8.4V nominal
- Energy backup of 37.8 watt-hr.
- PC/104 footprint size.
- Available with built-in RTC.
- Input for a "dry" contact to wake HESC out of hibernation.
- Digital I2C temperature sensor for detecting battery temperature.
