1 0RQB-30Y05L RoHS Compliant Rev.D Features Isolated Input under-voltage protection High Efficiency Output over-voltage protection Hold-up function Over current and short circuit protection Remote ON/OFF Over temperature protection Conformal coated 5V auxiliary supply at primary side Wide input range (24 V,48 V,72 V,96 V,110 V typical) Class 2, Category 2, Isolated DC/DC Converter (refer to IPC-9592B) Approved to EN , 2 nd +A2 version Applications Industrial Railways Description The 0RQB-30Y05L is an isolated DC/DC converter providing 30 W of output power from a wide input range (24 V, 48 V, 72 V, 96 V, 110 V typical). Standard features include remote on/off, input under-voltage protection, output over-voltage protection, over current and short circuit protection. This converter can also provide a 5 V/5 ma auxiliary supply. When a large hold-up capacitor is added, the converter can still work up to 12 ms when the input supply is interrupted. Conformal coated PCB is used for environmental ruggedness. Part Selection Input Voltage Output Voltage Max. Output Current Max.
