0RQB-30Y05L series rugged 30W 1/4 brick isolated DC-DC converters

Bel Power Solutions and Protection announces the 0RQB-30Y05L, a rugged 30 W quarter brick isolated DC-DC converter. The 0RQB-30Y05L provides 30 W of output power from an ultra-wide input range from 16.8 – 137.5 VDC and operates on all nominal battery voltages from 24 to 110 V with one module, making it ideal for railway and harsh industrial applications.

The 0RQB-30Y05L is designed for embedded computing, communication and control systems, such as Ethernet switches, TCMS, passenger information systems, on-board WLAN and door control. Standard features include remote on/off, input under- and over-voltage protection, output overvoltage protection, overcurrent and short circuit protection. This converter also provides a 5 V/5 mA auxiliary supply, which is typically used for Wake-On LAN applications. The hold-up circuit achieves a 10ms interruption time with smaller amount of external capacity and saves board space. Conformal coated PCB is used for environmental ruggedness; also approved to EN 60950-1 and designed in accordance to EN 50155.
