Variable fan speed controller 4 A | From High to Low
Product description
TRIAC controller designed for single-phase motors, specifically for controlling fan speed. It uses phase angle control to fine-tune motor voltage and achieve precise speed regulation.
There is the option to deactivate the OFF position and customize minimum speed. Additionally, all models include an extra unregulated 230 VAC output.
The enclosure is intended for surface mounting only and its protection rating is IP54.
Additional specifications and description
Simplified infinitely variable manual control
This residential fan speed controller has been developed to regulate motor speed steplessly from high to low using a single button – the rotary knob! When it is in the OFF position, the motor is disabled, while by turning the knob clockwise the motor is enabled at maximum speed. Turning it further in the clockwise direction slows the motor down to the minimum speed setting. To set the minimum motor speed you can avail the internal trimmer. If necessary, you can deactivate the OFF position and the motor will operate when the power supply is detected. If you choose to have the OFF position disabled, simply connect the supply voltage via terminals intended for the unregulated output.
Reliable fan speed control
The MTX series are manually operated stepless room speed controllers. They are a solid and simple solution thanks to their nice looks and long service life. In residential environments it is important that the motor does not produce too much noise. That is why the MTX features an internal trimmer to adjust the minimum motor speed within the range 20 – 70 % of the supply voltage. Its purpose is to avoid motor stalling and excessive noise at low speed and optimize fan speed for your ventilation system.
Unrivalled simplicity of installation
This fan speed controller is fit for surface mounting, meaning you can install it onto all kinds of walls – solid walls, gypsum board or wooden panels. All you need is a couple of every day tools – screwdrivers and pliers, a little bit of general knowledge and handiness.
Application
The MTX series is intended for control of AC fans by reducing the motor voltage. AC fans run on an alternating current and convert alternating current into mechanical power. The MTX series reduce the voltage via phase angle control. The controllers are suitable only for voltage controllable motors. If you are not sure about the type of your motor, we strongly advise on contacting the fan manufacturer or reading carefully its accompanying documentation.
Unregulated output
The series features an unregulated output used to control external devices such as a damper, relay, run indicator, etc. If you connect the supply voltage as standard and as advised by the relevant documentation, the unregulated output of your controller will be active when the motor is enabled. This means that when the fan stops, the connected external device will be disabled – the damper will be closed or the run indicator will go out. While the fan works, the damper will be open and the indicator light will be on. Because this output is ON (230 Volt) or OFF (0 Volt), it is called ‘unregulated' and its maximum current is 2 A.
Robust and nice housing
The enclosure of the series is made of top-quality durable ASA plastic, which is UV resistant and of high ingress protection rating - IP54 for surface mounting. This means it provides protection against ingress of dust, dirt and water in indoor applications. You can easily clean it using only a damp towel.
