    Power factor correction(PFC): Passive and active(IEC61000-3-2)


    Soft start, adjustable acceleration, CVT


    Design operating temperature range: -30~60 degrees of minimum selection(The device in accordance with -40~85 degrees)


    Protection: over voltage, over temperature, over current, phase loss detection, communication failures.


    The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma


    The basic parameters of field programmable: Maximum speed, minimum speed, maximum power,


    Let’s assume a laminar flow workstation requiring 13200m³/h at 450Pa. This requires 4 off Ø315 backward curved fans.


    Now let us assume that this workstation operates for 50 weeks of the year and for 8 hours per day at full speed. During non working hours to


    maintain the work area, the fans are run at roughly half the airflow.

    AC fan 2800hrs @ 4 x 1.41kW = 5.64kW 15,792 kWh
    5600hrs @ 4 x 0.62kW = 2.48kW 13,888 kWh
    Total A 29,680 kWh
    EC fan 2800 hrs @ 4 x 1.04kW = 4.16kW 11,648 kWh
    5600 hrs @ 4 x 0.27kW = 1.08kW 6,048 kWh
    Total B 17,696 kWh
    A minus B 11,984kWh saved with the EC fan


    aster/Slave : This system is used when several fans are used together within a single application. The main fan (Master) is individually pressure


    controlled. The other fans (slaves) are then speed controlled by the Master fan : Slave Fans are always at the speed of the master fan (Rosenberg Versions only).
