The RS Series front ends have 2500W output with active power factor correction in two models of 24 vdc at 104.2A and 48 vdc at 52.1A. Power density is 11W/in.3 in a fan-cooled, low profile case with dimensions of 3.3" x 4.9" x 14". Two other models come with identical performance with the addition of output isolation diodes for parallel and/or redundant applications. The front ends are designed to drive a dc power bus for distributed power systems using dc-to-dc converters. The series has a Class B input EMI filter, single-wire current sharing between units, no minimum load requirements, and 250,000 hours MTBF by the Bellcore method. And the supplies have a 5V, 100 mA independent supervisory output. They also offer over-voltage, thermal, overload and short-circuit protection and a number of control and monitoring functions. Input voltage range is 170 to 264 vac, and efficiency is 82% to 85%.
