Electronic fan speed controllers
Electronic fan speed controllers are a simple and efficient way to control the speed of your fan by adjusting the voltage. They offer several benefits that make them a great choice for both home and industrial use.
First, they help you save energy by letting you run the fan at the speed you need, instead of always using full power. This means lower electricity bills, which is great for anyone looking to reduce costs, whether at home or in the workplace. Another advantage is reduced noise. Fans running at lower speeds make much less noise, so these controllers are perfect for places where quiet is important, like offices, homes, or libraries.
Using an electronic fan speed controller can also extend the life of your fan. By reducing strain on the fan’s motor, it wears out less quickly, so you won’t need to replace it as often. This means fewer maintenance headaches and long-term savings.
Finally, these controllers are very flexible and easy to use. You can set the fan to work exactly as needed, whether it’s for keeping your living room comfortable or for precise airflow in a factory. They work well in both simple setups and more complex systems, making them a versatile solution for almost any situation.
AC fan electronic speed controllers
The VRE..R-S/H series fan speed controllers are a simple and efficient way to control the speed of single-phase fans by adjusting the voltage. They’re versatile and easy to use, making them suitable for many different applications at home or in industrial settings. They can be installed using either surface mounting or flush mounting, making them easy to integrate into your setup.
A great feature of these controllers is that you can connect multiple fans to one controller, if their total current doesn’t exceed the controller’s limit. They also have a built-in knob (potentiometer) that lets you set the minimum fan speed, giving you more flexibility to meet your needs. To keep your fans working reliably for a long time and avoid potential issues, it’s recommended to install motor protection with the speed controller.
Features
- Current options: 1.5 A and 2.5 A
- S version: Controls fan speed from minimum to maximum
- H version: Controls fan speed from maximum to minimum
- Fixed output: 230 VAC
- Installation options: Surface-mounted or flush-mounted
- Protection class: IP44/IP54 (resistant to dust and splashes)
These controllers are built to last and are ideal for managing fan speeds effectively in any environment. Thanks to their protection class, they can handle tougher conditions, whether in homes or workplaces.

Electronic fan speed controllers with light indicator
The VRE..P-S series electronic fan speed controllers are advanced and practical devices designed to control the speed of single-phase fans by adjusting the output voltage. These controllers are highly versatile and can be easily used in both residential and industrial area where precise fan speed control is needed.
One of the key features of this series is the built-in LED indicator, which makes it easy to see if the controller is working. This adds extra convenience for everyday use and allows users quickly to check if the system is active.
The VRE..P-S electronic fan speed controllers can be installed using either surface mounting or flush mounting, making them easy to integrate into your setup. They also support connecting multiple fans to one controller, but it’s important to ensure the total fan current doesn’t exceed the controller’s maximum capacity. Additionally, the internal knob (potentiometer) lets you adjust the minimum fan speed, ensuring flexible and efficient performance. To keep everything running smoothly and avoid problems, it’s a good idea to install motor protection with the speed controller.
Features
- Controller current: 1.5 A and 2.5 A
- Speed control: From minimum to maximum
- Built-in LED indicator: Shows operating status
- Fixed output: 230 VAC
- Installation types: Surface-mounted or flush-mounted
- Protection class: IP44/IP54
These controllers are reliable, long-lasting, and well-suited for a variety of environments, including challenging conditions requiring high resistance to moisture or dust. They ensure smooth fan operation, reduce energy consumption, and minimize noise, making them an excellent choice for both home and industrial use.

Electronic fan speed controllers with onn-off switch
The VRE..T-S series fan speed controllers are simple and reliable devices for adjusting the speed of single-phase fans. They are designed for industrial use, where it's important to control fan speed efficiently and flexibly. These controllers can handle a maximum current of 10 amps, making them suitable for powerful fans.
They offer two operating modes:
- Kick start mode: The fan starts at full speed for 8–10 seconds, then slows down to the speed you’ve set with the control knob.
- Soft start mode: The fan starts directly at the speed you’ve set, ensuring a smooth and gentle startup.
Each controller also has an ON–OFF switch, so you can easily turn the fan on or off when needed. These controllers can be installed using either surface mounting or flush mounting, making them easy to integrate into your setup.
Features
- Handles currents: 3.0 A, 5.0 A, and 10.0 A
- Two start modes: Kick start and soft start
- Simple ON–OFF switch for easy control
- Fixed output: 230 VAC
- Installation options: Surface-mounted or Flush-mounted
- Protection level: IP54 (resistant to dust and splashes)
These controllers are great for keeping fans running smoothly, even in tough conditions. They save energy, reduce wear on the fan, and are built to last. Perfect for anyone looking for a practical and efficient fan control solution!
