Bel Power Solutions 0RQB-30Y05L Isolated DC-DC Converter

Bel Power Solutions 0RQB-30Y05L Isolated DC-DC Converter provides 30W output power from a wide input range (24V, 48V, 72V, 96V, 110V typical). This Bel Power Solutions DC-DC converter includes remote on/off, input under-voltage protection, output over-voltage protection, over-current, and short-circuit protection. 0RQB-30Y05L can also provide a 5V/5mA auxiliary supply. When a large capacitor is added, this converter can still work up to 12ms when the input supply is interrupted. A conformal-coated PCB provides environmental ruggedness.
