Features: 
This regulator is 5pcs of a special circuit for motor speed regulation. The minimum voltage that can be adjusted by a precision multi-turn potentiometer.

Parameter:
Use voltage: AC 220V

Maximum power: 2000W

Voltage regulation: AC 50-220V

Specification size: High temperature resistant FR-4 circuit board circuit board 36MM*48MM

Outer size: 48MM*60MM (knob direction) *28MM (height)

Control silicon withstand voltage up to 1200 volts / current 25A

1.6mm thick epoxy copper clad laminate

The voltage regulator with a peak voltage absorption circuit effectively protects the high-power thyristor, and has a longer life and more durability.

Instructions:
 Connect the product in series with the lamp of the desk lamp or the appliance, (ie, disconnect the lamp or the electrical appliance from any of the live or
neutral wires, and connect the two wires of the "product" to the rotary potentiometer.) Rotating rod can play the role of brightness adjustment,
speed regulation, pressure regulation and temperature adjustment; it is very convenient to use.

This product is suitable for: using the new bidirectional high-power SCR, because the current can reach 25 amps,
which solves the overcurrent problem caused by the electric resistance of the electric furnace wire being too small in the case of cooling;
Can be very convenient to adjust the output voltage of mains electricity, in 90-- 220 volts between arbitrary adjustment, power supply for use.
Such as: electric furnace, water heater heating, lighting dimming, small motor speed, electric iron temperature adjustment. Thereby achieving
the effects of dimming, temperature regulation and pressure regulation. Large-scale electrical appliances that can be used with electric power less than 2000 watts are generally large
enough to be used in general household appliances or small factories.
