ITEM NAME:4000W 110-220VAC Voltage Regulator Dimmer Electric Motor Speed Controller Module Description: This item has two-way large power silicon controlled rectifier and the current can be up to 20A, which is a good solution to over current of electric stove wire caused by low resistance during cooling. Voltage regulator. Input voltage: AC 110V to 220V; Output voltage varies from 0V to 220V AC; Max Power: 4000W(resistive load) Convenient to use, simply connect input terminals to either live wire or neutral wire(110V to 220V) and output to load, then rotate knob to control voltage Wide voltage regulating range.the output voltage can be easily adjusted from 0V to 220V 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: Input Voltage: AC 110V to 220V Max Power: 4000W(resistive load) Output Voltage: Variable from 0V to 220V AC Size: 85 x 60 x 45mm / 3.34 x 2.36 x 1.77 inch Package Includes: 1 Piece Voltage Regulator Note: The resistive load power should be less than 4000W, and power should be largely reduced(half or more) for inductive or capacitive loads, otherwise controller and load will burn out. SKU: DMO0010089773021328.Max Power: 4000W(resistive load).
