Bel Power Solutions Introduces 50 W Quarter Brick Isolated DC-DC Converters from 24 to 110 V


Bel Power Solutions, a Bel group company, announced 0RQB-50Y Series, a rugged 50 W quarter-brick isolated DC-DC converter. It 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, onboard WLAN, PoE applications, and door control.

Key Features of the 0RQB-50Y Series are:

  • 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 a smaller amount of external capacity and saves board space. 
  • Conformal coated PCB is used for environmental ruggedness.
  • Approved to IEC/EN/CSA/UL 62368-1 standard and designed under EN 50155 regulations.
