Standard 90–264VAC (universal input range).

Frequently marked as Wan Nien E88653 , 101V0 , and carries a 94V-0 flammability rating . Even without the exact schematic, most Wannien 101V0

Before diving into the schematic details, it is vital to understand what the Wannien 101V0 architecture is designed to handle. This unit is primarily found in variable, regulated DC bench power supplies. 110V/220V AC (Switch-selectable) Output Voltage Range: 0–30V DC (Typical configuration)

However, successful repairs of this board have been documented. The key is to adopt a methodical approach: verify the input safety components first, then move to the high-voltage section, and finally troubleshoot the output stage. The specific component values and testing tips provided in this article can serve as a starting point for your diagnosis. Your most valuable tools will be patience, careful observation, and a safe testing setup. Before diving into the schematic details, it is

This document summarizes a verified power-supply schematic for the Wannien 101V0 device, highlights key design elements, lists component values and protections, and provides practical notes for builders and troubleshooters.

Dynamic tests

This component provides feedback from the output side to the input side, ensuring the voltage stays constant.

Turn the main voltage knob completely counter-clockwise. Adjust the zero-adjust trimpot until a digital multimeter across the output terminals reads exactly 0.00V.
