Digital Voltage Regulator Speed Control, Akozon Voltage Controller 4000W SCR Electric Voltage Regulator Dimmer Temperature Motor Speed Controller With Fan

【Wide Application】This is an easy-to-use voltage regulator to control light brightness, speed or temperature. It can be widely used as a thermostat for electric furnaces, water heaters, dimmers for lamps, speed controllers for small motors, thermostats for electric soldering irons, etc. 【Triac】This Voltage Regulator Speed Controller has a bidirectional high-power thyristor rectifier, and the current can reach 20A, which solves the problem of overcurrent caused by low resistance when the electric furnace wire is cooled. 【Compact Design】This power supplies speed controller has a compact design, only 85 x 60 x 45mm / 3.34 x 2.36 x 1.77inches, which is convenient for many small projects. 【Easy to use】The Dimmer scr motor controller is easy to use, just connect the input terminal to the live wire or neutral wire (110V to 220V) and output to the load, then turn the knob to control the voltage. With a wide voltage adjustment range, the output voltage can be easily adjusted between AC 0-220V input voltage. 【Tips】The resistive load power should be less than 4000W. For inductive or capacitive loads, the power should be greatly reduced (half or more), otherwise the controller and load will be burned out.
