2500W, Rectifier/Battery Charger for 120V Batteries BCH 2K5 – 120NP-EQ Series • • • • Rugged industrial quality Field-proven design Convection cooling – no fans Full electronic protection 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 o o applications with -40 C 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 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. Input Voltage 240Vac, 47-63Hz 190-264Vac operating range Input Current: 23Arms max PFC-input versions are also available Input Protection Inrush current limiting Varistors Internal safety fuses Input breaker also for AC ON/OFF Lower input voltages than the specified minimum will not damage the unit Input Isolation 2250VDC input to chassis 4300VDC input to output 8mm spacing 1000VDC output to chassis Standards Designed to meet EN 60950-1 and corresponding UL/CSA standards.
