MEGMEET 2700W Titanium SiC Server PSU Teardown: IPS122700-AOT-S2A, 12V 225A in CRPS185
2026-10-08 · Compiled by Best IT Parts from public industry reporting
A teardown of the MEGMEET IPS122700-AOT-S2A examines a 2700W titanium-grade server power supply. The unit accepts 100-120V and 180-264V AC input as well as 180-320V DC input, with a main 12V output rated at 225A and a 12V/3A standby rail. It uses the standard CRPS185 form factor and measures roughly 185 x 73.7 x 40 mm at about 997 g. The label rates 2700W maximum on 220-264V input, 2100W on 180-220V, and 1250-1400W on 100-120V.
Inside, the design combines totem-pole PFC, a full-bridge LLC stage and synchronous rectification, built around STMicroelectronics silicon-carbide switches. The PFC fast leg uses SCT027TO65G3 SiC devices rated 650V and 29 mΩ, driven by isolated gate drivers, while the slow leg uses Infineon IPT60R022S7 CoolMOS S7 devices rated 600V and 22 mΩ with TI UCC21220 drivers. The full-bridge LLC section uses four Infineon IPT60R035CFD7 CoolMOS CFD7 switches rated 650V and 35 mΩ, driven by TI UCC21550 isolated drivers.
Control is handled by TI TMS320F280037 parts, one for PFC and one for LLC, running a 120 MHz core with 256KB flash and 69KB RAM. Isolation relies on TI ISO7741 and ISO7762 digital isolators, while current sensing uses an Allegro ACS733 sensor with 1MHz bandwidth and 3600 Vrms isolation plus a Belling BL0942 metering IC. Synchronous rectification uses Infineon BSC007N04LS6 MOSFETs rated 40V and 0.7 mΩ, driven by TI UCC27511A drivers. Output filtering is provided by Fujitsu 3300µF/16V capacitors, with a 450V/1470µF high-voltage bus capacitor on the primary side.
For B2B buyers, the teardown reflects how 2.7kW-class CRPS supplies are consolidating around SiC totem-pole PFC and high-current 12V rails. That component mix, including SiC switches, isolated gate drivers and high-capacity solid output capacitors, is worth tracking for anyone sourcing replacement modules and board-level spares.
