Electrolytic capacitors near heat sinks are the most frequent culprits. Look for bulging tops or leakage. Blown Fuse:
, which helps minimize energy waste and heat generation during operation. Safety Standards wannien 101v0 power supply schematic exclusive
Unlike cheaper supplies, the Wannien 101v0 includes a located at RV1 on the schematic. This clamps voltage spikes. Directly behind it is a common-mode choke (L1) with a 20mH rating. Exclusive tip: If the supply is dead but the fuse is okay, check RV1 for a short circuit. Electrolytic capacitors near heat sinks are the most
