The DCS 480 Converter

Description:

Delta DCS 480 is a hot-pluggable,fan-cooledconverter which converts typical +24 Vdc input to-48Vdc (48V) for various telecommunication applications. The high power density DC/DC module employs thestart-of-the-arttechnology 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.
