Description

The 0RCR-40S10x Series are isolated DC/DC converters that operate 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 300 W

of output power from a nominal 48 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 eighth-brick package.
