Variable fan speed controller 1,5 A | From High to Low
Product description
Control fan speed with a TRIAC controller designed for single-phase motors. Utilizes phase angle control to fine-tune motor voltage and speed regulation.
Achieve precise speed regulation from high to low.
The OFF position can be deactivated. Ideal for voltage-controllable single-phase motors with up to 1,5 A current. Customize minimum speed using an internal trimmer.
Versatile enclosure for IP44 inset or IP54 surface mounting. All models have an extra unregulated 230 VAC output.
Additional specifications and description
Easy fan speed control
This residential fan speed controller regulates motor speed from maximum to minimum. It is controlled manually and when the rotary knob is in OFF position, the motor is not active. Turning the knob clockwise starts the motor at the highest speed. When the knob is turned further clockwise, the motor slows down to the minimum speed setting.
Application
The device is intended only for voltage controllable fans / motors, i.e. AC fans. These run on an alternating current and convert alternating current into mechanical power. These controllers reduce the voltage provided to the fans via phase angle control using TRIAC technology. If you are not sure about your motor type, we strongly advise you to read carefully its accompanying documentation or contact the motor manufacturer.
Adjustable minimum speed using internal trimmer
The minimum motor speed is adjustable via an internal trimmer within the range 20 – 70 % of the supply voltage (Us). As a rule, the minimum motor voltage is adjusted to avoid motor stalling at low speed and optimize fan speed for your ventilation system. What is more, when the motor works at very low revs there is humming and buzzing, which disturbs the building occupants. The trimmer must be adjusted so that the motor does not stop due to mains voltage variations.
Disabled OFF position
The OFF position can be deactivated by connecting the 230 VAC supply voltage to the unregulated output, i.e. to terminals ↓ and N (intended for the unregulated output). In this case, the motor will run when the power supply is present. If you want to keep the OFF position enabled, connect the supply voltage via terminals ↑ and N, as standard.
Unregulated output to control external devices
If the supply voltage is connected to ↑ and N, the unregulated output is active when the motor is enabled. The unregulated output can be used to control external devices. It is intended for use in applications where good regulation or low ripple is not required, such as an LED lamp (as a run indicator), external relays, solenoids, dampers and anything that is ideal for non-critical loads. When the fan stops, the external device is switched off. When the fan is active, the external device is on. Because this output is either ON (230 Volt) or OFF (0 Volt), it is called ‘unregulated output’.
Spare fuse
The MTX features two fuses – a working and a spare one. Both of them are placed in the holder of the device itself. No need to look for a fuse in case the working one blows due to overloading its capacity or a short circuit! You can find the right size and type of fuse in the device itself.
Control more than one fans
You can connect several motors to the controller as long as the current limit is not exceeded. In this case all of them will run at the same speed.
One enclosure, different mounting possibilities
The enclosure is made of high-quality ASA plastic. This material is UV resistant; it looks very nice and protects the electronics against ingress of dust, dirt and water and features both inset and surface mounting. The protection class is IP44 for inset mounting and IP54 for surface mounting.
