Single phase transformer fan speed controllers
5 – step transformer fan speed controllers are used to control the fan speed by changing the supply voltage to the fan. There are single-phase and three-phase transformer controllers. With one-speed controller it is possible to control several motors if the sum of currents of all motors does not exceed the maximum current of the speed controller.
Transformer fan speed controllers | Maximum current 1,5 A
Single phase transformer fan speed controllers TFC series let manually control the fan speed in 5 steps: 0-120-150-170-200-230V. TFCA transformer fan speed controller is for controlling fan speed of extract fans, TFCB – reversible controller. Fan speed is controlled from minimum to maximum (from low to high speed). The controller doesn’t have the possibility to connect fan TK contacts. Switches are also installed in the controller to switch on and off the power supply. These transformer fan speed controller's enclosures are made from ABS plastic.
Features
- Power supply 230 VAC, 50 – 60 Hz
- Unregulated output 230 VAC
- Power range 0,8 - 1,5 A
- Ambient temperature 25 – 35 °C
- Ambient humidity 5 – 95 % (not condensate)
- Protection class: IP54
| Product code | Max current, A | Fuse ( 5 x 20 mm), A |
|---|---|---|
| TFCA – 08 / TFCB - 08 | 0,8 | F – 1,5 |
| TFCA – 10 / TFCB - 10 | 1,0 | F - 1,25 |
| TFCA -15 / TFCB - 15 | 1,5 | F – 2,5 |
Transformer fan speed controllers | Maximum current 11 A
Single phase transformer fan speed controllers TE and TES series let manually control the fan speed in 5 steps: 0-85-150-105-130-230V. Fan speed is controlled from minimum to maximum (from low to high speed). TE series controllers don’t have the possibility to connect fan TK contacts, but TES series controllers have it. When the fan is overheating, the controller stops the fan and starts again when the problem is solved. It is needed to turn on 5 step switches to position 0 and turn it on again. These transformer fan speed controllers till 7,5 A enclosures are made from ABS plastic, 11 A - from metal sheet.
