Bel Power Solutions announced 0RQB-50Y Series, a rugged 50 W quarter brick isolated DC-DC converter. The 0RQB-50Y Series provides 50 W single output voltages of 5V, 12V, 15V, 24V and 48V from an ultra-wide input range from 14.4 to 154 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-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.
