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.

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).
