5-Speed Controller with Auto Transformers \nThis is a speed controller for three-phase 400 VAC motors. Versions are also available for single-phase motors and three-phase 230 VAC motors. The speed controllers for single-phase motors are equipped with one auto transformer, while the versions for three-phase motors have two auto transformers. Using the built-in switch, you can select one of the 5 speeds. \n \nAuto or auto-transformer technology is highly reliable and robust. It generates motor voltage with a perfectly sinusoidal waveform, identical to the mains voltage. This results in exceptionally quiet motor operation and an extended motor lifespan. A specially impregnated coating reduces the electrical noise of the auto transformers. Mehr Produktdetails

Produktbeschreibung

This is the 6 Ampere model from the well-known STR-4 series of speed controllers, which includes models ranging from 1.5 to 14 A. The STR-4 allows you to control the speed of your three-phase fan. Thanks to autotransformer technology, it delivers a well-regulated output voltage to your fan, ensuring smooth motor operation and extending the fan's lifespan. Using the external rotary knob on the device, you can select from 5 speeds. An additional 230 VAC output is provided as soon as the rotary knob is turned from the zero position. This can be used to connect, for example, a damper or an operational status indicator lamp.
