Transformer fan speed controller | 3 x 230 VAC | 13 A


Product description

AC fan speed controller for three-phase 230 V motors. The (combined) maximum motor current is 13 A. The AC fan speed can be selected via the rotary switch. This 5-step rotary switch also has an OFF position. The motor speed is regulated in 5 steps by varying the motor voltage. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation. The enclosure offers an IP54 protection against ingress of dirt, dust and moisture. It can be wall mounted in indoor environments. The supply voltage is 3x 230 VAC.

Additional specifications and description


5-step speed controller for AC fans
This is a controller for three-phase 230 V motors. Via the built-in switch, you can select one of the 5 speeds . Autotransformer technology is used to reduce the motor voltage and the fan speed in 5 steps. This technology is very reliable and robust. It generates a motor voltage with perfect sinusoidal shape. This results in exceptionally quiet motor operation and extended service life. A special impregnated coating reduces the electrical noise from the autotransformers.

Easy to install!
This fan speed controller doesn't require configuration. Once installed, it can be used.
 
Unregulated output
The extra, unregulated output (1x 230 VAC) is active when the motor is enabled. It can be used to control an external run-indicator, a damper, etc.
E.g. when the fan is deactivated, the dampers is closed. When the fan is active, the damper is open.

Solid enclosure
The enclosure is made of high-quality steel. The enclosure can be surface mounted and offers an IP54 protection against ingress of dirt, dust and moisture.
