Feature:_x000D_ _x000D_ 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. _x000D_ The product can easily adjust the output voltage, between 50 and 220 volts, for the use of electrical equipment with different voltage requirements. _x000D_ Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc.). Most single-phase AC motors are also available (but not guaranteed). _x000D_ The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc. _x000D_ 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). _x000D_ _x000D_ Specification:_x000D_ Voltage: 220V_x000D_ Max power: 2000W (Resistive load ultimate power)_x000D_ Voltage adjustment: 50-220V AC_x000D_ Board: High Temperature Resistant FR-4 Circuit Board_x000D_ _x000D_ Package list:_x000D_ 1 x Controller_x000D_ _x000D_ Note:_x000D_ 1.
