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.
