AC motor 1,5 A | Differential pressure control 0 - 1.000 Pa | DIN rail
Constant pressure control for AC fans with single-phase motor. The maximum motor current is 1,5 A. The fan speed is automatically controlled to maintain the differential pressure constant. The differential pressure setpoint can be adjusted via Modbus RTU. In case of clogged air filters or increasing demand for fresh air supply, the fan speed will increase to maintain the differential pressure constant. Minimum and maximum fan speed can be adjusted via trimmers. If necessary, a remote start-stop command can be generated via an external switch (not included).
