EC fan potentiometers
We could offer a wide range of potentiometers for controlling the speed of EC fans. Potentiometers are possible with a power supply of 12 VDC, 24 VDC or 230 VAC. They also have different output signals: 0 – 10 V or PWM. There are potentiometers with minimum and maximum fan speed adjustable. All our potentiometers could be surface or inset mounting.
EC fan potentiometer | Control signal 0-10 V
EC – MT series potentiometers are used to control EC fans by signal 0 – 10 V. They are with a power supply of 10 VDC or 24 VDC. They also have dry contact. 24 VDC power supply potentiometers could be used to control the frequency inverter and power supply to take from frequency inverter. They are inset and surface mounting.
Features
- Supply voltage 10 VDC or 24 VDC
- Output 0 - 10 VDC
- Dry contact max 4A / 250VAC
- Flush and surface mounting
- Protection class IP44 / IP54
| Product code | Power supply, VDC |
|---|---|
| EC – MT10 | 10 |
| EC – MT24 | 24 |
EC fan potentiomer | Power supply 230 VAC
EC – MTV series potentiometers are used to control EC fans by signal 0 – 10 V. They are with a power supply of 230 VAC. This potentiometer also has dry contact. They are inset and surface mounting.
Features
- Supply voltage 230 VAC, 50 – 60 Hz
- Output 0 - 10 VDC
- Load min 1 kOm
- Dry contact max 4A / 250VAC
- Flush and surface mounting

EC fan potentiomer | Control signal PWM
EC – PWM series potentiometers are used to control EC fans by PWM signal. PWM signal is controlled from 10 to 100%. When the potentiometer switches off output signal are 0%. The potentiometer needs a power supply of 230 VAC. They also have dry contact and are inset and surface mounting.
Features
- Supply voltage 230 VAC, 50 – 60 Hz
- Output 10 - 100 % PWM
- Dry contact max 4A / 250VAC
- Flush and surface mounting
- Protection class IP44 / IP54
EC fan potentiomer | Min & max speed adjustable
EC – MTD potentiometer are used to control EC fans by output 0 – 10 V. Power supply is required from 3 VDC to 15 VDC. Possibility with internal trimmers to adjust the minimum and maximum speed. They also have dry contact and are inset and surface mounting.
Features
- Supply voltage 0 – 10 VDC
- Output 0 - 10 VDC
- Dry contact max 4A / 250VAC
- Flush and surface mounting
- Protection class IP44 / IP54
