Absopulse Releases 2500W, Rectifier/Battery Charger for 120V Batteries in Heavy-duty Industrial Environments

Absopulse released the BCH 2K5-120-EQ rugged, industrial quality battery charger that uses field-proven high-frequency conversion technology to deliver up to 2500W continuous output power. This charger accepts an input voltage range of 190 to 264Vac, and in float-mode it provides 135Vdc/16A for charging a 120V (60 cell) battery. Other input/output values are available on request.

This design also has a manually initiated equalize cycle. Activated by a push-button "EQ/ON", the equalize function elevates the output voltage to 141Vdc for the battery. The equalize time is controlled by a built in timer, adjustable in the 1-9 hour range. This mode can be manually de-activated at any time.

The BCH 2K5-120-EQ is rated for heavy-duty applications with -40 to +70°C temperature rating for full specification. Cooling is by convection via louvers on the cabinet. The absence of fans, low component count and the use of components with established reliability result in a high MTBF. The robust chassis was designed for a wall-mounted application.

This charger is constructed with internal modules, connected in parallel, which also provide inherent redundancy: the failure of one module would only cause a minor loss in total output power. The charger output is equipped with a built-in crossbar diode and output breaker as a safety feature against accidental reverse battery connection. Other protection includes input inrush current limiting, over-voltage protection, short circuit protection, and a self-resetting thermostat for thermal protection. An optional Charger Fail Alarm (Form C) indicates loss of ac input power.

The BCH 2K5-120-EQ is priced in the US$2,211 range at low quantities (5 to 24), depending on options required.
