Features 1、A new type of bi-directional high-power thyristor is used, because the current can reach 25 A, which solves the problem of over-current caused by too small resistance of the electric furnace wire in the case of cooling. 2、The product can easily adjust the output voltage, between 50 and 220 volts, for the use of electrical equipment with different voltage requirements. 3、Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc.). Most single-phase AC motors are also available (but not guaranteed). 4、The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc. 5、The ultimate resistance load power of the product is 2000 W. It should be reduced for a long time. It is suggested that the resistance load should be less than 1000W at room temperature (key parameters, please note).
