Precautions and Usage Instructions
1. Ensure Proper Voltage Measurement: When the machine operates without a load, the measured output voltage is only virtual. For an accurate voltage reading, connect a load of at least 20W before adjusting the voltage.
2. Suitable Power and Voltage Range: Please operate 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 rating 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 generate 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. Incompatibility with Soft Start Voltage Regulators: This machine is not designed to work with soft start or slow start voltage regulators. Additionally, it should not be used with ordinary LED lights and household appliances.
7. The power switch includes an overload protection function. If the power is switched off due to overload, it can only be turned on again after a certain period when the overheating protection has been triggered. To resolve the issue, reduce the connected load.
