These units will provide up to 150 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 93%. Features include remote on/off, over current protection and under-voltage lockout. These converters are provided in an industry standard quarter brick package. Part Selection Output Voltage Input Voltage Max. Output Current Max.
