Wannien 101v0 Power Supply Schematic Exclusive !exclusive!

Wannien E88653 (101V0 / 94V-0) is a versatile power supply board frequently used in laboratory experiments, industrial automation, and electronic testing. While "exclusive" schematics are often gatekept by repair professionals, general technical analysis of this board shows it is a reliable, high-efficiency unit capable of adjustable performance. Core Specifications Variable Output : Typically supports adjustable voltage from and current up to , making it suitable for moderate-power applications. Efficiency : Rated at up to 80% efficiency

PWM Controller: Often uses an 8-pin IC (like the LD75xx or SG68xx series). wannien 101v0 power supply schematic exclusive

Scenario C: Output Drops to 18V Under Load

• Check the current sense resistor (R10 on primary). The schematic identifies a 0.22 ohm / 3W resistor.
• As resistors age, their value drifts up (e.g., to 0.5 ohms). This fools the KA7500B into thinking the current limit is exceeded, throttling the voltage.
• The Fix: Solder a new 0.22 ohm metal film resistor in parallel if you can't find the exact type.

Bottom line: The “exclusive” Wannien 101V0 schematic is not publicly available. Your best path is to identify the main control IC and use its reference design as a reliable substitute. Wannien E88653 (101V0 / 94V-0) is a versatile

Output Voltage: Typically adjustable or fixed between 0V and 30V DC.

A bridge rectifier converts AC to pulsating DC, smoothed by a high-voltage electrolytic capacitor (often rated for Switching Stage:
