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. : Always discharge the large high-voltage capacitors before

The (often labeled under the model numbers E88653 or 94V-0 ) is a widely used power supply board found in various monitors, industrial equipment, and adjustable laboratory bench supplies.
