Fan speed controller | remotely controlled | 3,5 A
Product description
This 5-step fan speed controller may be controlled remotely via 5 inputs. It controls single-phase motors. The highest (combined) current is 3,5 A. The power supply voltage is 230 volts.
The AC fan speed is controlled by adjusting the motor voltage in up to five steps. An external switch or control device can be used to choose the various steps. The control switch type SMT-1-30-4C is recommended. This is a three-position switch with an off position.
The exact sinusoidal form of the output voltage ensures silent motor running.
Surface mounting is possible in infoor environments (IP54).
Additional specifications and description
Simple fan speed control in steps
Transformer based fan speed controllers are widely used in industrial kitchens, warehouses or industrial environments. They are the preferred choice there since they offer simple control for regulating extractor hoods or exhaust fans. The fan speed can be increased from standstill to maximum speed in steps. When connected, this controller can be used immediately. No configuration or programming is required. AC fan speed control made easy!
Autotransformer technology
This fan speed controller is intended for single-phase motors. The autotransformer technology is used to reduce the motor voltage and the fan speed. This controller is suitable for voltage controllable motors. If you are not sure whether your motor is voltage controllable, it is best to contact the motor manufacturer.
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 control
This series of transformer fan speed controllers is a simplified manual control solution. The RTR-1 series does not feature the standard knob on its enclosure but can be controlled 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!
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.
E.g. when the fan stops, the damper is closed. When the fan is active, the damper is open.
Application
The series is designed specifically to control AC fans by reducing the motor voltage. AC fans operate using alternating current and convert it into mechanical power. That is why they are compatible only with voltage controllable motors. It is possible to connect multiple motors to the controller, provided that the current limit is not exceeded. In such cases, all connected motors will operate at the same speed. If you are uncertain about the type of motor you have, it is strongly recommended to carefully review the accompanying documentation or contact the motor manufacturer for further assistance.
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 retardant, 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.
