2pcs Ac Motor Speed Controller Ac 220v 2000w Thyristor Motor PXCL WalkbeeA 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 The product can easily adjust the output voltage, between 50 and 220 volts, for the use of electrical equipment with different voltage requirements Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc ) Most single-phase AC motors are also available (but not guaranteed) The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc 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) Specification:Voltage: 220Vpower: 2000W (Resistive load ultimate power)Voltage adjustment: 50-220V ACBoard: High Temperature Resistant FR-4 Circuit BoardColour:As shownMaterial:Composite materialSize:48MMx60MMx28MMPackage Contents:2 x ControllerOnly the above package content, other products are not included Note: Light shooting 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
