Description
The 0RQB-C0U Series are isolated dc/dc converters that operate from a nominal 48 Vdc source. These units
will provide up to 100 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 91%. Features include
remote on/off, over current protection and under-voltage lockout. These converters are provided in an industry
standard quarter brick package.
