Hi
Please be aware that there was at least five different vendors power supplies used in the 2023/2025 series and that they did not all use the same type of output pins, some used screw terminals.
The supply that you have is a Lambda-Coutant unit. Invariably the four 100uf 250VDC main bulk storage capacitors fail and this results in multiple problems within the supply. If it is used on 230VAC and even more nasty failure can occur. This supply is auto 115VAC or 230VAC switching, when used on 230VAC a brown out can cause it to switch to 115VAC but not switch back for 230VAC when the brown out ceases. They don’t like 230VAC when in 115VAC mode and quit with extreme prejudice.
With the exception of the output pins, which are screw terminals, the MW RQ-125D is a physical and electrical direct drop in replacement.
When replacing the power supply please make certain the +5VDC supply is set to 5.2VDC to allow for internal voltage drops in the 2023/2025, other wise the CPU can have a mental break down.
