Features:Thisitem has new two-way large power silicon controlled rectifier and the current can be up to 80A, which is a good solution to over-current of electric stove wire caused by low resistance during cooling.It can easily adjust the output voltage on a scale of 0-100% (nonlinear) to power electric device.Designed with large and thick heat sink that would enhance heat dissipation.This voltage regulator is adjusted with button which is much more stable than potentiometer.Voltageregulator has wave voltage absorbing circuit and effective protects large power silicon controlled rectifier, longer service life and more durable.It can be used as power supply for large electrical devices, enough for household appliances or for small factory.Could be widely used as heat controller on electric stoves, water heaters, light dimmer on lamps, speed controller on small motors, or temperature controller on electric soldering iron, etc.Specification:Voltage: AC 220VMax Power: 10000W(instantaneous limit power for resistive load; for long time use, 5000W or lower is recommended)Voltage Adjustment: 0-100% (nonlinear)Controller Size: 9.7*5.7*5.4cm / 3.8*2.2*2.1inPanel Size: 7.5*6*1.7cm / 3*2.4*0.7inPanel Screw Hole Spacing: 6*4.5cm / 2.4*1.8inCable Length: 28.7cm / 11.3inWeight: 227g / 8oz (approx.)Package list:1 * SCR Controller1 * ABS Panel1 * CableNote:1,AC input, AC output, output voltage is lower than(or equal to) input voltage; voltage can be adjusted only when connected to load; mainly used for resistive load(e.g. heating wire, incandescent light bulb).2,It can not replace electric bicycles' battery charger, nor drive electric appliances which use switch power supply (such as 110V TV, speaker, refrigerator, air conditioner, rice cooker with a computer), and cannot drive induction cooker, energy saving lamp.
