## Description

SCR AC 4000W voltage regulator for fine control of light intensity or speed of compatible motors, mounted in series on the 220V circuit and allows voltage adjustment between 10 and 220V. Offers efficiency over 90% and is ideal for resistive loads, being a simple solution for power regulation in domestic or industrial applications.
4000W AC voltage regulator suitable for dimmer type applications (light intensity regulation) but also for motor speed control.
This regulator is usually used with resistive loads and may not work with any type of AC motor.
The module is connected in series on the AC circuit.
For inductive or capacitive loads, the maximum supported power is reduced by half.
As a good practice, we recommend using modules with half of the specified maximum specifications.
