Teardown: Suplet 2900W SiC Rectifier Module SR4850M-1U — PFC + Full-Bridge LLC + Synchronous Rectification
2026-09-16 · Compiled by Best IT Parts from public industry reporting
Suplet's SR4850M-1U is a hot-pluggable 2900W rectifier module for power shelves: 100-250V AC input (19A max), 53.5V DC at 54.2A output, 267 x 105 x 40.5mm, 1,776g, with a gold-finger rear connector, front air intake and rear exhaust via a 12V 0.66A ball-bearing fan. The topology is PFC plus full-bridge LLC plus synchronous rectification. Key silicon: Rohm SCS210AG 650V/10A SiC Schottky PFC rectifiers, Dongwei OSG60R074HSZF 600V/74mR MOSFETs for PFC and LLC switching, TI TMS320F28022 and TMS320F28032 C2000 MCUs for PFC and LLC control, Infineon IPP075N15N3 G 150V/7.2mR synchronous rectifiers, and an Infineon ICE5QR2280AZ QR flyback auxiliary supply. High-voltage bulk filtering uses Dongyangguang 450V/470uF and 390uF capacitors; output filtering eight Samyoung 63V/470uF parts; input safety and filtering from Jianghai, Faratronic and Yudian X2/Y capacitors with Tyco relay and BrightKing MOVs.
