Product Description The rectifier EP3000AC48TE is a high Efficiency, single phase, hot-pluggable, fan-cooled rectifier and battery charger for stand-alone use or for working in parallel as part of a DC power system equipped with advanced digital controller. The constant output power (3000W i.e. 55.5A at 54V) characteristic supplies the specified power over the full output voltage range (48 to 58Vdc). It’s backwardly compatible to earlier version of EP rectifier i.e. EP2500AC48/EP3000AC48. Highly efficient rectifier Efficiency ≥ 95% There is a digital communication (RS-485 bus) between rectifier and controller which allows flexible system design. Highly rugged rectifier Exclusively designed to take care of wide line fluctuations and extreme climatic conditions prevailing typically in rural/ semi-urban areas (“B” & “C” telecom Circles) of India  Can withstand up to 500Vac (Line-Neutral) continuously without any damage (for battery floated application)  Can withstand 96 hrs of salt spray test (as per ASTM B117), Special protective coating on the PCBs and superior plating on the metal parts  Can work up to +70C Optimum power performance Constant power between 176V … 300V ac, linearly de-rated power between 175V … 90V ac Compact and light Six rectifiers can be accommodated in one row (23” shelf) implying more compact system Applications The typical applications for this rectifier are both in indoor and outdoor environments and include: ■ ■ ■ ■ Telecommunication Equipment Power Wireless Cell Site Power Systems Central Office Power Plants Base Station Power Plants AIR FLOW DIRECTION (FRONT TO BACK) FRONT VIEW SIDE VIEW
