2 Pcs Speed Controller for AC Motor AC 220V 2000W Thyristor Motor Speed Control Adjustable Power Controller p2024112652<br> A new type of bi-directional high-power thyristor is used, because the current can 25 A, which solves the problem of over-current caused by too small resistance of the electric furnace wire in the case of cooling.<br> The product can easily adjust the output voltage, between 50 and 220 volts, for the use of electrical equipment with different voltage requirements.<br> Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc.). Most single-phase AC motors are also available (but not guaranteed).<br> The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc.<br> 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).<br> Specification:<br> Voltage: 220V<br> power: 2000W (Resistive load ultimate power)<br> Voltage adjustment: 50-220V AC<br> Board: High Temperature FR-4 Circuit Board<br> Colour:As shown<br> Material:Composite material<br> Size:48MMx60MMx28MM<br> Package Contents:<br> 2 x Controller<br> Only the above package content, other products are not included.<br> 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.<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
