5-Wire DC Brushless Fan Testing Board with Storage Box for Internal and External Fan Detection

Instruction:
- The usual definition of a 5-wire DC fan is: red wire 310V, black wire GND ground, white wire VCC15V, yellow wire VSP speed regulation, blue wire FG feedback. Please verify that the plug wire is on the corresponding terminal. Equipped with short-circuit protection and soft start function, no potentiometer adjustment is required.
1: Firstly, the red wire of the fan corresponds to the 310V end, and then check if other wires are on the corresponding terminals.
2: Verify that there are no errors, then power on for testing. The red light indicates the power supply, and the green light indicates the feedback of the fan.
- If the green light is on and the fan does not rotate, it means the fan is faulty.
- When the green light is on and the fan is rotating, it means the fan is normal. (Flashing and stays on at high speed when turning slowly)
- Attention: the circuit board comes with high voltage, please do not touch the circuit board when powered on.
