0RCR-30S12X

ISOLATED DC/DC CONVERTERS 48 VDC Input 11.8 VDC/25 A Output, 1/8 Brick 0RCR-30S12x • • • • • Isolated Fixed Frequency High Efficiency High Power Density Low Cost RoHS Compliant • • • • • Rev.E Input Under-Voltage Lockout Input Over-Voltage Shutdown OCP/SCP Over Temperature Protection Remote On/Off Description The 0RCR-30S12x are isolated DC/DC converters that operate from a nominal 48 VDC source. These converters use a full bridge power train to provide isolation and step down. These units will provide up to 300 W of output power from a nominal 48 VDC input. These units are designed to be highly efficient and low cost. Features include remote on/off, over current protection and under voltage lockout. These converters are provided in an industry standard eighth-brick package. Part Selection Output Voltage 11.8 V Input Voltage 48 V Max. Output Current 25 A Max. Output Power 300 W Typical Efficiency 96% Model Number Active Low 0RCR-3012L Model Number Active High 0RCR-30S120 Notes: 1.
