Description
The 0RCM-60S10x is isolated DC/DC converter that operates from a nominal 48 VDC source. These converters
use a full bridge power train to provide isolation and step down. These units will provide up to 530 W of output
power from a nominal 55 VDC input. These units are designed to be highly efficient and low cost. Features
include remote on/off, over current protection and under voltage lockout. These converters are provided in an
industry standard quarter -brick package.
