Description
The 07QB-C5T Series are isolated DC/DC converters that operate from a nominal 48V source. These units will provide up to 150W of output power from a nominal 48V input. These units are designed to be highly efficient and low cost. Typical efficiency of 12V output at 48V 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.
