💚 1. The Voltage Regulator Is Ac Input And Ac Output. It Can Only Step Down And Adjust The Voltage When The Load Is Connected. 💚 2. The Voltage Regulator Is More Suitable For Industrial Enterprises That Need Low Voltage To Drive The Heating Wire: Such As Cutting Styrofoam, Pearl Cotton, Raincoat Production, Etc. 💚 3. The Voltage Regulator Is Mainly Used For Resistive Loads (Electric Heating Filament Incandescent Lamps, Etc.). 💚 4. Stepless Speed Regulation, Light Regulation, Temperature Regulation, Voltage Regulation, Output 0-220v For Easy Support And Control. 💚 5. Fully Isolated Ac Module Regulation, High Precision, High Efficiency, High Power, High Temperature Resistance. 💚 6. Adjust Voltage, Speed, Temperature, And Lights. Suitable For Resistive Loads (Electric Heating Filament Incandescent Lamps, Etc.) 💚 7. Led Digital Display Output Voltage, The Maximum Output Voltage Is The Input Voltage. 💚 8. Note: For The First Use, Turn The Potentiometer Counterclockwise To The End Before Turning On The Power. Otherwise, If You Connect A Load Such As A Heating Wire With A Small Resistance Value, It Will Burn Out Immediately After Power-On. 💚 9. Matters Needing Attention: The Power Used Cannot Exceed The Power Of The Voltage Regulator. It Is Recommended That The Resistive Load Is 5000w; The Inductive Load Is 3000w. 💚 10. Note: The Metal Casing Of The Voltage Regulator Must Be Safely Grounded. 💚 11.Matters needing attention: The load current exceeds 13A, connect to the output terminal at the rear of the voltage regulator.
