SCR Speed Controller 220V for AC Motors 6kW/10kW

SCR Speed Controller for AC Motors - 220V 6kW/10kW

Our SCR controllers (thyristors) provide reliable, efficient, and compact speed regulation for AC motors!

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

SCR controllers adjust the output voltage of the AC supply, much like a ceiling fan controller or a lighting dimmer. These controllers can be effectively used with single-phase AC motors to adjust their speed. They can also be used with resistive loads, e.g., for lighting.

It is very important to note that these controllers do NOT work with capacitor-start motors, which are common in single-phase applications. These motors have a visibly large capacitor that limits their speed/pull. Slowing down is not possible with capacitor motors!

Brightness control with energy-saving bulbs, LED lights, and devices containing electronics is not possible!

Motors that can have their speed regulated by SCR controllers are motors with permanently connected start capacitors (PSC), permanent split capacitor (PSC), and universal motors. This includes all single-phase types of motors that can be regulated using SCR controllers - however, there may be certain limitations. Our SCR controllers can be used for most small household appliances and electric tools.

The SCR controller does not have a wide range for speed regulation - the control is likely to be positioned in the upper half of the settings. To achieve smooth motor operation before slowing down, the power of the SCR controller needs to be increased.

How to choose the right controller:

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

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