| ISOLATED DC/DC CONVERTERS 48 VDC Input 9.6 VDC/40 A Output, 1/8 Brick 0RCR-40S10x * * * * * Isolated Fixed Frequency High Efficiency High Power Density Low Cost RoHS Compliant * * * * * Rev.E Input Under-Voltage Lockout Input Over-Voltage Shutdown OCP/SCP Remote On/Off Over Temperature Protection Description The 0RCR-40S10x Series 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 9.6 V Input Voltage 48 V Max. Output Current 40 A Max. Output Power 300 W Typical Efficiency 96.5% Model Number Active Low 0RCR-40S10L Model Number Active High 0RCR-40S100 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.
