Absupulse Compact DC-output UPS/Battery Charger With Universal Input Delivers 100W

Absopulse Electronics introduced its BCH 100, a compact dc output UPS system designed for industrial and other rugged environments. The built-in battery charger section provides 100W power for the output and for float charging the external battery. Standard single output float voltage options include 13.8, 27.6 or 55.2Vdc. The unit operates from a 95 to 264Vac universal input. Custom input and output options are available on request.

The BCH 100 has a low battery disconnect circuit to prevent damage to the external battery by low discharge during prolonged ac failure. The battery input is also protected against accidental reverse battery connection by a crossbar diode and internal safety fuse. A built in redundancy diode prevents battery discharge back in to the charger if the ac is disconnected or collapses. This unit also features a charger fail alarm (Form A) to indicate either failure of the charger circuit or loss of ac input power. A charger ’ON’ LED indicator is located beside the terminal block.

This compact UPS system is conduction and convection cooled, requires no fan, and is rated for operation over a 0 to +50°C range without derating. An extended temperature range is available on request. Other options include heavy ruggedizing and conformal coating for operation in extreme environments. The unit is fully protected and meets EN 60950 and related international standard requirements.

The BCH 100 is priced in the range of US$150 at quantities of 100.
