Features [Good stability] The voltage regulator is adjusted by a button, which is much more stable than a potentiometer. [Easy to use] This dimmer can easily adjust the output voltage in the range of 0-100% (non-linear) to power electrical equipment. [Strong heat dissipation] The voltage regulator is designed with a large and thick radiators to enhance heat dissipation. [Long service life] This speeds controller has a waves pressure absorption circuit, which effectively protects the high-power silicon controlled rectifier, and has a longer service life and more durable. [Main application] This scr controller has two-way high power, and the current can be as high as 80A. It is a good solution to the overcurrent caused by the low resistance of the electric furnace wire during cooling. Specifications: Voltage: AC 220V Maximum Power: 10000W(instantaneous limit power for impedance load; for long time use, 5000w or lower is recommended) Voltage Adjustment: 0-100% (nonlinear) Controller Size: 95.7*56.7*53.8mm/3.76*2.23*2.11" Panel Size: 74.6*59.8*2.3mm/2.93*2.35*0.09" Cable Length: 287mm/11.3" Note: 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. 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.
