Electronic fan speed controllers
Electronic fan speed controllers are a product group that allows you to change the speed of the fan by changing the output voltage. Of course, it could be used only with single-phase fans, in which speed could be changed by voltage control, not frequency. There are small residential fan speed controllers and industrial fan speed controllers. Usually, it is used to control AC motors and pumps.
AC fan electronic speed controllers
Electronic fan speed controllers FSR series are used to control single phase voltage controllable fans. Controllers are suitable for wall and flush mounting. Multiple fans can be connected to one electronic controller, but in this case, the total current of fans couldn’t be bigger than the controller's maximum current. Fan speed controllers have an internal trimmer to set minimum fan speed.
Recommendation to install motor protection together with electronic controller.
Features
- Current range 1,5 A and 2,5 A
- L version - speed control from minimum to maximum
- H version - speed control from maximum to minimum
- Unregulated output 230 VAC
- Flush and surface mounting
- Protection class: IP44/IP54
| Product code | Max current, A | Current range, A | Fuse ( 5 x 20 mm), A |
|---|---|---|---|
| FSR - 15 - L | 1,5 | 0,1 – 1,5 | F – 2,0 |
| FSR - 25 - L | 2,5 | 0,2 – 2,5 | F - 3,15 |

|---|---|---|---|
| FSR - 15 - H | 2,5 | 0,1 – 1,5 | F – 2,0 |
| FSR - 25 - H | 2,5 | 0,2 – 2,5 | F – 3,15 |
Electronic fan speed controllers with light indicator
Electronic fan speed controllers PSR series are used to control single phase voltage controllable fans. These fan speed controllers have a light indicator, which shows if the controller is in working mode or not. Electronic fan speed controllers are suitable for wall and flush mounting. Multiple fans can be connected to one electronic controller, but in this case, the total current of fans couldn’t be bigger than the controller's maximum current. Fan speed controllers have an internal trimmer to set minimum fan speed.
Recommendation to install motor protection together with electronic controller.
Features

| PSR - 25 - H | 2,5 | 0,2 – 2,5 | F – 3,15 |
Electronic fan speed controllers with onn-off switch
Industrial electronic fan speed controllers are developed to control single-phase voltage controllable fans. The maximum current is 10 Amps. These fan speed controllers have 2 working modes: kick start and soft start. When the controller is working on kick start mode, then the motor always starts or restarts at maximum speed for 8 – 10 seconds and after that motor speed automatically follows the potentiometer position. The motor always starts in a potentiometer position in soft start working mode. Industrial fan speed controllers have an on-off switch.
Recommendation to install motor protection together with electronic controller.
Features
- Current range 4,0 A; 6,0 A and 10,0 A
- ON – OFF switch
- Kick start or soft start mode
- Unregulated output 230 VAC
- Surface mounting
- Protection class: IP54.
