Control transformer - Import export

The STR-1-15L22 is a transformer fan speed controller with which you can manually regulate the fan speed of single-phase motors in 5 steps. The unit also has an off-position. It needs a 230 VAC/50-60 Hz supply voltage and has an unregulated output of 230 VAC that can control a damper, an external status indicator, etc. This output is active as soon as the motor is enabled. The sinusoidal shape of the generated motor voltage results in an exceptionally quiet motor operation and extended service life. The special impregnated coating reduces the electrical noise from the built-in autotransformer. This series is available in different amperes. The casing of the controllers up to 7,5 A is made from high quality plastic, while the models above 7,5 A have a metal housing. This transformer doesn't need any configuration. Once installed, it's ready for use.
