The new bidirectional high-power thyristor is used, because the current can reach 80 amps, which solves the over-current problem caused by the resistance of the electric furnace wire being too small when it is cooling; it can easily adjust the output voltage of the mains. 0-100% (adjustable at 220 volts, 100 levels, non-linear), for electrical appliances.Such as: electric furnace, water heater, dimming of lamps, small motor speed, electric iron temperature. So as to achieve the effects of dimming, temperature and pressure. Available for large appliances with an electric power of less than 10,000 watts.Because the power is already large, ordinary household appliances or small factories are sufficient. (The power of the inductive or capacitive load should be reduced. This voltage regulator is equipped with a bidirectional high-power thyristor, which can be used without adding any components.Use voltage: AC 220VHigh power: 10000W resistive load limit power, it is recommended to use within 5000W at room temperature for a long timeVoltage regulation: 0-100% (220 volts 100 level adjustment, non-linear)Material:Metal + plasticcolour:SilverPackage Contents:1 * 1000W Digital voltage regulatorOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
