Description
The 07CM-38S “Cimarron” 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 54 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.
