Bel Power Solutions 0RQB-50Y05x 50W Isolated DC-DC Converters

Bel Power Solutions 0RQB-50Y05x Isolated DC-DC Converters provide 50W of output power from a wide input range (24V, 48V, 72V, 96V, 110V typical). The quarter-brick converter provides 5V/5mA auxiliary supply, and when a large hold-up capacitor is added, the unit can still work up to 12ms when the input supply is interrupted. Bel Power Solutions 0RQB-50Y05x Series Isolated DC-DC Converters feature remote on/off, input undervoltage protection, output overvoltage protection, overcurrent, and short-circuit protection.
