Product description

This AC fan speed regulator, designed for residential environments, offers adjustable fan speed from low to high. With a combined maximum motor current capacity of 3 A, it's suitable for AC fans featuring a voltage-controllable single-phase motor. Users can fine-tune the minimum fan speed via an internal trimmer. The unregulated output remains active when the motor is enabled.


The housing supports both inset and surface mounting options, and it operates at a supply voltage of 230 VAC. Phase angle control, utilizing TRIAC technology, is employed to decrease the motor voltage and effectively manage fan speed. This variable speed controller is frequently employed to regulate a variety of applications, including ceiling fans, bathroom exhaust fans, and extraction fans, among others.

Additional specifications and description


Extra simple manual control
 
This controller is intended for fan speed regulation from minimum to maximum speed. Regulation is done manually via the rotary knob (potentiometer). When the knob in the OFF position, the fan is inactive, and of the knob clockwise, the motor starts operating at minimum speed. Turning it further clockwise speeds the fan up to its maximum revs. The SDY features an internal trimmer (marked with Vmin) for adjusting the minimum fan speed. If you like, you can deactivate the OFF position, which means the motor will operate when power supply is available. If you choose to have the OFF position disabled, simply connect the supply voltage via the terminals marked with L1 and N on the terminal block.
 
Silent motor operation 
For residential buildings it is important that the motor does not produce too much noise, otherwise occupants will be greatly disturbed. The new SDY speed controller is very similar to the old MTY controller, but better. Compared to the old series, the novel SDY offers extra precise control, thanks to the use of a microcontroller. Thus, the motor voltage can be controlled extremely accurately. The result is silent motor operation, even at lowest speed setting. 

Use
The SDY series is developed to control AC fans by reducing the motor voltage. AC fans run on an alternating current and convert alternating current into mechanical power. The SDY controllers decrease the voltage using the so called TRIAC technology via phase angle control. Therefore, they are suitable only for voltage controllable motors. If you are not familiar with your motor type, we strongly advise you to read carefully its accompanying documentation or better contact the manufacturer.

Sophisticated housing 
The most obvious new characteristic of the SDY series is their exquisite design. The enclosure is the ideal match for any interior style. What is more, it allows both surface and flush mounting. If you opt for flush mounting, the mounting holes fit perfectly the standard European wall boxes. The enclosure material is high-quality ASA plastic with UV and impact protection. Its rating is IP44 for flush mounting and IP54 for surface mounting, which means the device is protected against ingress of dust, dirt and water in indoor applications. On top of that keeping it clean requires only a damp cloth. Inset installation of a fan speed controller

Easy installation 
This variable fan speed controller can be mounted on all kinds of walls – solid, gypsum board or even wooden panels. You do not have to choose between two types of enclosures, because the SDY has both. All you need are a couple of simple instruments, skilled hands and some technical knowledge. 
 
Connecting external devices 
The SDY features an unregulated output, called so because it is either ON (230 Volt) or OFF (0 Volt). If the supply voltage is connected to L and N, the unregulated output is active while the motor is in operation. You can use this output to control external devices (2 A maximum current), for example a run-indicator or a damper, etc. This means that while the fan is working, the damper will be open or the run indicator will be on. When its stops, the damper will close and the indicator will be off.

The successor to an icon. These new fan speed controllers control the motor noticeably much quieter than the good old MTY series. The fan runs remarkably quietly, especially at low speeds.
