| ISOLATED DC/DC CONVERTERS 48 VDC Input 9.6 VDC/60 A Output, 1/4 Brick 0RCM-60S10x * * * * * Isolated High Efficiency High Power Density Low Cost RoHS Compliant * * * * OCP/SCP Rev.E Input Over-Voltage Shutdown Thermal Shutdown Remote On/Off Input Under-Voltage Lockout Description The 0RCM-60S10x is isolated DC/DC converter that operates 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 530 W of output power from a nominal 55 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 quarter -brick package. Part Selection Output Voltage 9.6 V Input Voltage 48 V Max. Output Current 60 A Max. Output Power 530 W Typical Efficiency 97% Model Number Active Low 0RCM-60S10L Model Number Active High 0RCM-60S100 Notes: 1. Add "G" suffix at the end of the model number to indicate Tray Packaging. 2. All part numbers above indicate RoHS 6. Change the second letter "R" to "7" for RoHS 5 part numbers.
