Description
The 0RHB-D0T Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units
provide up to 200 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 half-brick package.
