Overload Protection Switch
The independent switch controls the input and output voltage, providing overload and short circuit protection. It replaces boat-shaped switches and fuses.

Precision Voltage Adjustment Knob
Voltage adjustment utilizes a precise potentiometer, offering high accuracy and excellent stability.

Tool Kit Hanging Hook
To facilitate the operation of an angle grinder, a tool kit hanging hook is designed for attaching tool bags. Its unique design ensures enhanced safety and practicality.

Precautions and instructions for use
1. Ensure proper voltage measurement: When the machine is empty, the measured output voltage is a virtual voltage. To obtain the correct output voltage measurement, connect a load of at least 20W before adjusting the voltage.
2. Suitable power and voltage range: Please use the machine within the specified rated power and voltage range. It is intended for use with AC grid power only.
3. Power limits for different loads: The mentioned 4000W power refers to the maximum limit when using resistive loads. For inductive loads, such as series motors, the power should be limited to 1/3 of the resistive load power. Exercise caution when using the machine with circuit board electronic products.
4. Normal heat generation: It is normal for the machine to produce slight heat during operation. Place and use the machine in a dry and well-ventilated area.
5. Safety precautions: This product features a flame-retardant plastic shell and must be properly grounded. Ensure that the power outlet is grounded for safe operation.
6.Incompatible with soft start voltage regulators: This machine is not designed to work with soft start or slow start voltage regulators.
