Transformer fan speed controller 5 A | Low to high


Product description

Transformer fan speed controller for single-phase motors. The (combined) maximum current is 5 Amps. AC fan speed is regulated from low to high in 5 steps and can be selected via the rotary switch. This 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.

Additional specifications and description

  
5-step speed controller for AC fans
This is a controller for single-phase 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 (230 VAC) is active when the motor is enabled. It can control an external run-indicator, a damper, etc.
E.g. when the fan is deactivated, the damper is closed. When the fan is active, the damper is open.
  
Solid enclosure
The enclosure is made of high-quality r-ABS plastic. This material is exceptionally heat resistant, very tough and offers good protection against impacts. The enclosure can be surface mounted and offers an IP54 protection against ingress of dirt, dust and moisture.
