Notes and instructions for use

1. The measured output voltage of an airplane is a virtual voltage, and the correct output voltage can only be measured by connecting a load of more than 20W.

2. Input AC, output AC, not DC.

3. The 4000W mentioned above refers to the limit power when working under resistive load. The inductive load is one third of the resistive load.

Resistive load refers to tungsten filament lamp, heating wire, etc. Inductive load refers to series excitation motor, etc. Circuit board electronic products are carefully used.

4. The shell of this product is made of PC/PP flame retardant material.

Please be sure to read the product instructions before use, follow the steps!

The electronic pressure regulator is used in the form of a hot water bottle, and other high-power electrical appliances (such as a hair dryer, a hand warmer, and a rice cooker) are used in a similar manner.

1. Insert the input power cord of the electronic regulator into the dormitory socket or the plug, and adjust the socket knob counterclockwise to point to the 0 position;

2. Turn on the switch button of the hot water bottle (the high-power electric appliance without the button does not need to open the switch, and the hair dryer has multiple gears to open.

The maximum gear, so the wind is large) then plug the plug of the kettle into the transformer socket;

3. Slowly turn the regulator knob from the 0 position to the 60 position clockwise. At this time, the appliance can work. At this point, pay attention: if you feel

To get the water slowly, turn the knob clockwise and slowly to the 80 position. If there is a 60-position dormitory that has not been powered off (such as 55 positional disconnection)

Electric) Adjust the angle of the regulator knob back to a small point (such as 40 positions), it will not be powered off. Or turn the knob directly to the 40 position.

Stop for 20 seconds, then go very slowly to the 45 position, then pause for 20 seconds, then very slowly go to the 50 position... the same as above and so on to the dormitory

The limiter has a buffer time, you can go to the 60 position, and even the larger position will not be powered off. The greater the angle of clockwise rotation, the voltage

The higher the water, the faster the water is burned. But the possibility of a power outage in the dormitory is also greater. Almost all schools in the range of knobs pointing to 602 are not

Will be powered off;

4. After using the power switch, unplug the power cord and remember the position angle of the knob. You can follow the above steps when using it next time.

Tips: This product uses electronic smart products such as induction cooker, juicer, soya-bean milk machine, computer, etc. with caution.
