Description
The 0RCR “Cimarron” Series are isolated DC/DC converters that operate from a nominal 48 VDC source. These
converters use a half bridge power train to provide isolation and step down. These units will provide up to 140 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.
