<p>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.</p> <p>The product can easily adjust the output voltage, between 50 and 220 volts, for the use of electrical equipment with different voltage requirements.</p> <p>Thyristor is mainly used for resistive load (electric filament incandescent lamp, etc.). Most single-phase AC motors are also available (but not guaranteed).</p> <p>The product is suitable for controlling different electrical equipment, such as electric lamps, fans, motors, etc.</p> <p>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).</p> <p>Specification:</p> <p>Voltage: 220V</p> <p>power: 2000W (Resistive load ultimate power)</p> <p>Voltage adjustment: 50-220V AC</p> <p>Board: High Temperature Resistant FR-4 Circuit Board</p> <p>Colour:As shown</p> <p>Material:Composite material</p> <p>Size:48MMx60MMx28MM</p> <p>Package Contents:</p> <p>2 x Controller</p> <p>Only the above package content, other products are not included.</p> <p>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.</p>
