How Does This Controller Provide Stepless Speed Adjustment?
This controller is developed to regulate motor speed from low to high speed 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 minimum speed. Turning it further in the clockwise direction speeds the motor up to the maximum. To set the minimum motor speed you can avail the internal trimmer marked with Vmin. If you prefer, 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 L1 and N (as standard).
What Are the Key Improvements and Design Features of the SDY Series?
The SDY is Sentera’s latest series of manually operated room speed controllers. It is the descendant of the MTY controller; however, some substantial improvements have been implemented.
Firstly, the very precise control of the motor is what makes it different from the old series. This is achieved via the use of a microcontroller - the motor voltage can be controlled extremely accurately and before all – steplessly! The result is unusually quietly running motor, even at minimum motor speed.
Secondly, the most apparent new feature of the series is their plain, yet elegant design. In addition to its exquisite looks, the housing of the SDY is made of top-quality durable ASA plastic, which is UV resistant and of high IP rating - IP44 for inset mounting and 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 a damp towel.
What Are the Installation Options and Requirements?
This fan speed controller is fit for both surface and flush mounting, meaning you can install it in all kinds of walls – solid walls, gypsum board or wooden panels. The mounting holes fit perfectly the standard European wall boxes used for inset mounting. No need to opt for two different versions as the SDY has both of them! All you need is a couple of every day tools – screwdrivers and pliers, a little bit of general knowledge and handiness.

What Motor Types Are Compatible and How Is Speed Regulated?
The SDY 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 SDY series reduce the voltage via phase angle control (TRIAC technology). This series is only suitable for voltage controllable motors. If you are not sure about the type of your motor, please contact the manufacturer or read carefully its accompanying documentation.
How Does the Unregulated Output Function and What Are Its Applications?
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 to L and N, as standard, and as advised by the relevant documentation, the unregulated output of your SDY 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.
