Wall-mount battery charger BCH 2K5-120NP-EQ series

multi-chemistryfor railway applicationsadjustable

The BCH 2K5‐120NP‐EQ rugged, industrial quality battery charger uses field‐proven high‐frequency conversion technology to deliver up to 2500W continuous output power. In float‐mode it provides 135Vdc/16A for charging a 120V (60 cell) battery. The equalize function, activated by a push‐button “EQ/ON”, 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. The equalize mode can be de‐activated at any time by pushing the “EQ/OFF” button. 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 output power. The unit is rated for heavy‐duty applications with ‐40o C to +70o 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 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 unit is manufactured at our plant under strict quality control.
