Wannien 101v0 Power Supply Schematic Verified • Hot
Typically provides stable DC voltages for the mainboard and an inverter circuit for the monitor backlight. Efficiency: Modern versions of these boards boast up to 80% efficiency. Protection:
A verified schematic for the 101V0 consistently shows the AC input flowing through a standard safety fuse (F1). Technicians verifying this section should check the schematic against the PCB for the presence of an NTC thermistor (TH1), used to limit inrush current. wannien 101v0 power supply schematic verified
The Wannien 101v0 is popular for converting to a variable bench supply. Based on the verified schematic: Typically provides stable DC voltages for the mainboard
Most Wannien power supplies of this era utilize a switching mode design. You will likely find these four basic sections : You will likely find these four basic sections :
. If the voltage is abnormal, inspect the feedback loop and the reference voltage of the control IC (often around 12V). Connector Check:
