Art. no.: 76739
Demand controller for pressure and constant flow ventilation
Demand controller for EC-fans or e.g., a frequency inverter.
Possible control modes
Variable air volume (VAV)
Constant air volume (CAV)
User friendly menu, easy setup
Supply voltage directly from the fan. No additional supply voltage is necessary.
Controlled output signal: 0-10 V (Imax = 0.3mA)
Voltage supply with polarity reversal protection: 10-24 V DC(Imax = 6 mA)
Adjustable measuring range 0-1000Pa
Pressure ports + / -: for ∅ 5mm hose adapters ∅ 6 mm
Enclosure class IP54
The sensor control module for differential pressure and volume flow measures and indicates the pressure or, optionally, the volume flow in a ventilation system. The calculation of the volume flow is performed by entering the K-factor of the application.
Depending on the desired setpoint value and control range, the sensor control module generates 0-10 V to control the EC fan or e.g., a frequency inverter.
The sensor control module is supplied by the fan or frequency inverter which it controls, e.g., with 10-24 V DC.
