| ISOLATED DC/DC CONVERTERS 48 Vdc Input 12 Vdc/18 A Output 0RX3-D2T12x Isolated High Efficiency High Power Density Low Cost RoHS Compliant Rev.C Output Over-voltage Protection OCP/SCP Over Temperature Protection Remote On/Off Basic Insulation Baseplate Fixed Frequency (300 kHz) Input Under-voltage Lockout Input Over-voltage Lockout Description The 0RX3-D2T12x is an isolated dc/dc converter that operates from a nominal 48 Vdc source. This unit will provide up to 216 W of output power from a nominal 48 Vdc input. This unit is designed to be highly efficient and low cost. Features include remote on/off, over current protection and over-voltage protection. The converter is provided in an industry standard quarter brick package. Part Selection Output Voltage 12 V Input Voltage 36 V - 75 V Max. Output Current 18 A Max. Output Power 216 W Typical Efficiency 95% Model Number Active High 0RX3-D2T120 Model Number Active Low 0RX3-D2T12L 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.
