Bel Power Solutions’ DC/DC converters are offered in 5V, 12V, 15V, and 48V output options, with high input to output efficiency

Bel Power Solutions’ 0RQB-50Y05x series isolated DC/DC converter provides 50 W of output power from wide input voltage ranges: 24 V, 48 V, 72 V, 96 V, and 110 V typical with a maximum of 154 V. The quarter-brick converters provide multiple output voltage options: 5 V, 12 V, 15 V, and 48 V. 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. Bel Power Solutions’ isolated DC/DC converters feature remote on/off, input undervoltage protection, output overvoltage protection, overcurrent, and short-circuit protection. The conformal coated PCB is used for environmental ruggedness for industrial, railway, and other harsh environment applications.
