This EC fan controller has temperature, minimum- and maximum speed settings on three knobs for the exhaust fan. It is easy to use.
The EC fan controller is supplied with a 4m long cable including a 3.5mm 3pole stereo jack (Can-Fan) or RJ45 (Primaklima, Carbonactive) connector to the fan and a 4m long Temperature sensor. It comes as a finished product. The output signal is 0-10V or PWM (pulse width modulation) signal which can be set by a jumper.
An extremely low current consumption allows you to run the EC fan controller without power supply, powered directly from the EC fan.
Temperature: 20C° to 30C°
Minimum speed: off, 20% to -100%
Maximum speed: 100% to -50%
Is the power supply required?
With or without power supply? Depending your EC fan you need a supply current >10VDC >4mA and PWM signal you can run the controller without a own power supply. This information you have to get from the Technical data sheet of your EC fan. (Ruck or Can-Fan) EBM-papst motors, Primaklima, Systemair are working with PWM Signal)
If the EC-fan provide 2wire Signal-GND then yes,
Ii the EC-fan provide 3-4wire Signal-GND-VDC >10V/4mA there is no power supply required.
