The DCS 480 Converter

Description:

Delta DCS 480 is a hot-pluggable, fan-cooled converter which converts typical +24 Vdc input to -48 Vdc (48V) for various telecommunication applications. The high power density DC/DC module employs the start-of-the-art technology and provides high performance in efficiency, power density and extended operation temperature range. Up to 4 DC/DC power modules can be equipped into one 23” wide power shelf. Up to three shelves may be connected in parallel. The maximum capability can provide more than 5.5kW output power.

Features

•Module design for scaleable, cost effective expansion

•High efficiency

•Automatic load share, N+1 redundancy

•Hot swappable, no system shutdown for maintenance

•Reverse polarity protection design

•EMC Class B

•UL/cUL, TUV/CE Certified
