Regulated Bus Converter Provides High-Power Density 500 W Output Power


Santa Clara, CA - Bel Power Solutions and Protection announces the 0RCY-F0S10B, a next-generation regulated bus converter with 45-56 VDC input / 10.2 VDC @ 49 A output and offering up to 500 W of highly efficient power in an eighth brick footprint. This converter is intended to provide isolation and step down to generate a regulated intermediate bus for the purpose of powering non-isolated Point-of-Load (POL) converters.

The isolated DC-DC converter incorporates digital control, efficient secondary side synchronous rectifiers and a thermal management system. Thermal performances are extremally good because thermal design guarantee an efficient dissipation. Equipped with standard protection features like under voltage lockout (UVL), over temperature protection (OTP), over current protection (OCP), short circuit protection (SCP) and over voltage protection (OVP), Bel Power units also come standard with primary side on/off and secondary side Power Good signal indicators. The output of the converter includes the droop function, which allow the modules to operate in parallel with high output current sharing precision.

The 0RCY-F0S10B is IPC-9592B Class 2 and Category 2 rated as well as IPC-9592B derating compliant. Models all come with UL/CSA/IEC 60950-1, 2nd +A2 version (pending) approvals.
