FMP25.48 rectifiers save energy and deliver 25kW per rack unit in network power applications
(Product News, 08 May 2008 )
Power-One, Inc. has introduced the FMP25.48 rectifier. This energy-saving 2500-watt, -48V product delivers efficiencies exceeding 92%. Power densities surpassing 27 watts/cubic inch enable 25kW of power in a one rack-unit 23” shelf. A wide variety of distribution options are available to enhance flexibility when powering site-level communications applications such as wireless base stations, remote switches and broadband access.
Additional features include: a wide-range 90 to 300VAC input, high-input-voltage shutdown, and the ability to withstand a loss of phase or neutral without damage. Advanced resonant soft-switching topology significantly reduces rectifier component stresses to increase reliability. The FMP25.48 utilizes a compact 4.2” wide x 13.2” long x 1.6” high (107 x 337 x 40mm) package.
This rugged product is earthquake rated to GR 63 Core Zone 4 and exceeds EN61000-4-5 surge immunity. Safety agency approvals include EN 60950, UL 1950 and IEC60950, and CSA C22-2 No. 950. Evaluation models are usually available from stock. Production quantities are typically available in two to six weeks.
The PMP25.48 is compatible with Power-One’s energy-efficient Guardian Series of DC power solutions, which includes rack and cabinet systems that can deliver up to 500 amps with up to 720Ah of backup battery capability. Medium and large power requirements are also supported with 1200A per bay, up to 6400A. An extensive list of Guardian-Series options includes low voltage battery/load disconnects and AC surge protection.
