This regulator is specially designed for motor speed regulation. The minimum voltage can be adjusted by a precision multi-turn potentiometer.

parameter:
Use voltage: AC 220V
Maximum power: 2000W
Voltage regulation: AC 50V (about 50V, depending on the appliance will change slightly) -220V
Specification size: high temperature resistant FR-4 circuit board

The material used in this regulator:

Original imported thyristor, withstand voltage up to 1200 volts.

All are high voltage capacitors,

All are metal film resistors,

ST imported trigger diode,

Precision multi-turn potentiometer,

The main potentiometer is Taiwans big factory goods,

The materials are all excellent, they are purchased in large quantities after careful selection.

With a heat sink, the buyer can use it when they get it.

Instructions for use:

This product is suitable for: using the new bidirectional high-power thyristor, 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; it can adjust the mains easily The output voltage can be adjusted freely between 90----220 volts for use by electrical appliances. For example: electric furnace, heat adjustment of water heater, dimming of lamps, small motor speed control, electric iron temperature adjustment, etc. , temperature adjustment, voltage regulation effect. For large electric appliances with electric power less than 2000 watts, the power is already large, so the general household appliances or small factories are enough. (Inductive or capacitive load power should be reduced, this tone The pressure device is equipped with two-way high-power thyristor, and the potentiometer has a nut, which can be used without adding any components, which is very convenient and practical).
