Description
The 0RQB-C5T Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units will
provide up to 150 W of output power from a nominal 48 Vdc input. These units are designed to be highly efficient
and low cost. Typical efficiency of 12 Vdc output at 48 Vdc input at full load is 93%. Features include remote
on/off, over current protection and under-voltage lockout. These converters are provided in an industry standard
quarter brick package.
