Fan speed controller | remotely controlled | 1,5 A
Product description
This 5-step fan speed controller can be controlled remotely via 5 inputs. It controls single-phase motors.
The maximum (combined) current is 1.5 A. The power supply voltage is 230 volts.
The AC fan speed is controlled by varying the motor voltage in up to five steps. The perfect sinusoidal shape of the output voltage ensures quiet motor operation.
An external switch or control device can be used to select the various steps. The control switch type SMT-1-30-4C is recommended. This is a three-position switch with an off position.
Surface mounting is possible in indoor environments (IP54).

Why opt for a transformer-based fan speed controller
Transformer controllers are a robust, easy-to-use, efficient and affordable speed control solution. Another major advantage of transformer-based control units is speed control without electromagnetic excitation in the motors. The products are therefore also recommended for noise-sensitive premises. What you get by a transformer fan speed controller is: silent motor operation, simple control in steps and a controller with a long service life at a reasonable price!
Autotransformer technology is used to reduce the motor voltage and the fan speed in steps. Autotransformer 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.
Remote fan speed control
Transformer fan speed controllers are widely used in industrial kitchens, warehouses or industrial environments. They are often used as a simple control for regulating extractor hoods or exhaust fans. The fan speed can be increased from standstill to maximum speed in steps. What distinguishes the RTR-1 series is the fact that it does not feature the standard knob on it enclosure but can be controller remotely instead. All you have to do is connect an external device (switch) such as Sentera’s SMT-1-30-4C. So, your RTR-1 can be installed in the technical room or any appropriate location, where you will not hear the noises it produces, while the switch for controlling it can be close to you, so that you can easily control the ventilation according to your needs. When connected, this controller can be used immediately. No configuration or programming is required. AC fan speed control made easy!
Motor type
The series is developed to control AC fans via reducing the motor voltage. AC fans run on an alternating current and convert alternating current into mechanical power. Therefore, they are suitable only for voltage controllable motors. Several motors can be connected to the controller as long as the current limit is not exceeded. In this case all motors will run at the same speed. If you are not sure about your motor type, we strongly advise you to read carefully its accompanying documentation or contact the motor manufacturer.
Unregulated output
The extra, unregulated output (230 VAC) is active when the motor is enabled. Because this output is either ON (230 Volt) or OFF (0 Volt), it is called ‘unregulated output'. The maximum current of this output is 2 A. It is typically used to control an external run indicator, to open or close a damper, to switch an external relay, etc. When the fan stops, the damper is closed. When the fan is active, the damper is open.
Solid enclosure
Make sure that the fan speed controller can cool sufficiently. Preferably install it in a cool place, best not in direct sunlight. The enclosure is designed and manufactured in-house. We use high-quality r-ABS VO (UL94) plastic. This material is flame extinguishing, very tough and offers good protection against impacts. It offers an IP54 protection against ingress dust and water. This fan speed controller can be installed on a wall or panel indoors.
