Wannien 101v0 Power Supply Schematic Repack -

Working with switch-mode power supplies involves lethal voltages (up to 400V DC on the primary side). Capacitors can retain charge for days. Always discharge bulk capacitors through a 10kΩ/5W resistor before probing.

While a dedicated manufacturer "repack paper" is not publicly available, technician standards for this board type follow these steps: wannien 101v0 power supply schematic repack

The MOSFET’s gate is driven through a 22Ω resistor and a 1N4148 diode for turn-off speed. The drain is connected to the primary winding of the transformer and clamped by an RCD snubber (resistor 47kΩ, capacitor 102/1kV, diode UF4007). wannien 101v0 power supply schematic repack
