Edited by the Engineeringtalk editorial team Jan 20, 2009

Absopulse Electronics has released the BCH 501 series, a compact DC output UPS system/battery charger.

The unit utilises high-frequency conversion topology to generate 500W output power.

The input accepts a jumper selectable 115V AC or 230V AC, a 95V DC to 264V AC universal input with power factor correction, or 250V DC (220V to 370V DC range).

Standard output float voltages of 13.8V DC, 27.6V DC, 55.4V DC or 138V DC are available.

The BCH 501 is comprised of two vertically-stacked ('piggy-backed') chassis, which results in a small basal surface area for the entire system.

The lower chassis contains the basic charger section with charger fail alarm (Form C), battery temperature compensation and separation diode.

The UPS section, mounted on the power supply section, is entirely self-contained.

It features low battery disconnect, low battery alarm (Form C), as well as monitoring circuits for the battery condition, battery presence and battery fuse.

This 'piggy-backed' approach ensures changes can be made to either the charger or UPS sections separately.

A range of designs for both charger and UPS units are available.

The BCH 501 is conduction/convection cooled and requires no fan.
