• Demand-oriented control & energy savings: Motors run only at the necessary speed, significantly reducing electricity consumption.
• Noise reduction: A lower speed ensures a quieter and more pleasant operating sound for fans and extraction systems.
• Protection of hardware: Gentle start-up and lower speeds reduce mechanical wear and extend the service life of the equipment.

Product Overview

The 5-step speed controller is a powerful device specifically designed for the precise control of electric motors. With a voltage of 400 volts and a current of 14 amperes, this controller is ideally suited for use in demanding industrial and craft applications. The five adjustable steps allow flexible speed adjustment, thereby saving energy and extending the service life of the connected devices.

Product Details

The splash-proof housing ensures reliable use even in damp environments, while the lockable steel door provides protection against unauthorised access. The manual thermal shutdown protects the device from overheating, thus ensuring safe operation. Easy handling is supported by a clear step switch, with which the output voltages from 140 to 400 volts can be set in five steps. Additionally, the controller is designed for wall mounting and features an indicator light that shows the operating status.

Conclusion and Applications

This speed controller impresses with its high-quality workmanship and robust, galvanised steel insulated housing with protection class IP54. It is perfectly suited for use with radial fans and other motors that require stepped speed control. Thanks to its protective functions and flexible adjustment options, it is used in workshops, production halls, and building technology. Overall, the controller offers an efficient and safe solution for power adjustment of electrical devices.

⚠️ The verification of motor compatibility, the adjustment of the minimum speed to prevent overheating, as well as the proper shielding against motor hum should be carried out by a professional.
