AC Motor Speed Controller - SCR 220V/5kW

AC Motor Speed Controller - SCR 220V/5kW

Our SCR voltage regulators (thyristors) offer reliable, energy-efficient, and compact control of AC motor speed!

These variable SCR AC voltage regulators are specifically designed for vibrating feeders, fans, pumps, and heating and lighting equipment. All models come with a single-phase AC input and fully variable AC output.

SCR regulators adjust the output voltage of AC power similar to controlling a ceiling fan or a light dimmer. These SCR regulators can be used with single-phase AC motors, allowing for speed adjustments. They can also be used with resistive loads, such as lighting.

It is very important to note that these regulators do not work with motors that have a capacitive start, which is a common type of motor used in single-phase applications. These motors have a large bulge on the top or side, housing a capacitor that prevents any attempts at slowing down.

Dimming of energy-saving bulbs, LED lights, and other electronic devices is not possible!

Motors for which speed is regulated using these SCR regulators include permanently split capacitor (PSC), permanent split phase (PSP), shaded pole, and universal motors. These are all single-phase types of motors that can be controlled using SCR regulators, but this application may have certain limitations. Our SCR regulators allow for the regulation of most small household appliances and handheld power tools.

The SCR regulator does not provide a wide range for speed regulation; it will likely be in the upper half of the setting range. To move the motor before slowing down, it is necessary to increase the power of the SCR regulator.

How to choose the right controller:

For pure resistive loads, multiply the operating current by three. Example: (2.2kW/220V) * 3 = 30, the most suitable model will be 40A+

For inductive loads (motors), multiply the operating current by five. Example: (5kW/220V) * 5 = 22, the most suitable model will be 113A+
