Durable DC-DC Converter with Ultra-wide Input Range

Bel Power Solutions has announced 0RQB-50Y Series, a rugged 50W quarter brick isolated DC-DC converter.

The 0RQB-50Y Series provides 50W single output voltages of 5V, 12V, 15V, 24V and 48V from an ultra-wide input range from 14.4VDC to 154VDC and operates on all nominal battery voltages from 24V to 110V with one module, making it ideal for railway and harsh industrial applications.

The 0RQB-50Y Series is designed for embedded computing, communication and control systems, such as Ethernet switches, TCMS, passenger information systems, on-board WLAN, PoE applications 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 IEC/EN/CSA/UL 62368-1 and designed in accordance to EN 50155.
