0RQB-50Y12LG

The 0RQB-50Y12x is an isolated DC/DC converter providing 50 W of output power from a wide input range (24 / 48 / 72 / 96 / 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. • • • • • • • • • • • • • • • • 24/48/72/96/110 VDC Input 12 VDC @ 4.2 A Output Reinforced Isolation High Efficiency Hold-Up Function Remote ON/OFF Conformal Coated Input Over-Voltage Lockout Input Under-Voltage Protection Output Over-Voltage Protection Over Current and Short Circuit Protection 5V Auxiliary Supply at Primary Side Wide Input Range (24 V,48 V,72 V,96 V,110 V typical) Approved to IEC/EN 62368-1 Approved to CSA/UL 62368-1 Class II, Category 2, Isolated DC/DC Converter (refer to IPC-9592B) • • Industrial Railways 0RQB-50Y12x 2 MODEL NUMBER OUTPUT VOLTAGE INPUT VOLTAGE MAX.
