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. Part Selection Output Voltage 12 V Input Voltage 36 V - 75 V Max. Output Current 12 A Max.
