Transformer fan speed controller 0,8 A | Low to high
Product description
Transformer fan speed controller for single-phase motors. The (combined) maximum current is 0,8 Amps.
AC fan speed is regulated from low to high in 5 steps and can be selected via the rotary switch. This rotary switch also has an OFF position. The motor speed is regulated in 5 steps by varying the motor voltage. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation.
The enclosure offers an IP54 protection against ingress of dirt, dust and moisture.
It can be wall mounted in indoor environments.
This 5-step speed controller is often used to control kitchen hood exhaust fans, ceiling fans, extraction fans, etc.
Additional specifications and description
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!
Simple 5-step fan speed control
5-step 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 5 steps. When connected, this controller can be used immediately. No configuration or programming is required. AC fan speed control made easy!
The technology
This is a fan speed controller for single-phase motors. Via the built-in rotary switch, you can select one of the 5 speeds. Autotransformer technology is used to reduce the motor voltage and the fan speed in 5 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.
Use
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.
Rotary switch with built-in mechanical time delay
It is important to operate the rotary switch not too quickly. The switch has a built-in mechanical time delay. This is important to prevent internal sparking during shifting. It has a positive effect on the service life of the device. When the rotary switch is rotated from position faster than the built-in mechanical time delay, the device will remain internally at position 0 (OFF position).
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.
