Description
The 0RQB-C0U Series are isolated dc/dc converters that operate from a nominal 48 V source. These units will
provide up to 100 W of output power from a nominal 48 V input. These units are designed to be highly efficient
and low cost. Typical efficiency of 12 V output at 48 V input at full load is 91%. Features include remote on/off,
over current protection and under-voltage lockout. These converters are provided in an industry standard
quarter brick package.
