ISOLATED DC/DC CONVERTERS 48 VDC Input 8 VDC/15 A Output, 1/8 Brick 0RCR-15T Series • • • • • Isolated High Efficiency High Power Density Fixed Frequency Remote On/Off • • • • • RoHS Compliant Rev.B Input Under Voltage Lockout Output Overvoltage Shutdown OCP/SCP Low Cost Thermal Shutdown Description The 0RCR-15T Series are isolated DC/DC converters that operate from a nominal 48 VDC source. These converters use a half bridge power train to provide isolation and step down. These units will provide up to 130 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 8V Input Voltage 36 V-75 V Max. Output Current 15 A Max. Output Power 130 W Typical Efficiency 95% Model Number Active High 0RCR-15T08H Model Number Active Low 0RCR-15T08L Notes: 1.
