Tips: How to maintain switching power supply (SMPS)?

In case of power failure, users can carry out maintenance by visual check, smelling, asking and measuring.

Visual check: Open shell of the switching power supply to check whether the SMPS fuse has been blown. Check internal part of the SMPS power supply. If components on PCB are burned out, users shall check surrounding components and relevant circuit components.
Smelling: Check whether there is burnt smell in internal part of the SMPS power supply and whether there is burnt-out component.
Asking: Ask damaging process of the switching power supply and check whether there is violative operation.
Measuring: Use multimeter to measure voltage at both ends of the HV capacitor before powering on.

Existing reviews of 24V DC 12.5A 300W Switching Power Supply

Good steady 24V switching power supply

I bought two of these power supplies, 300w and 400w. Perfect for running two pumps in a vacuum system. The power supply ran 8hrs per day for two weeks without an issue. Good steady 24vdc power and meets the system amperage requirements.
