Product Description

  AVF508 series Low Voltage VFD has the following features:
  Multiple Control Modes:
  *Supports multiple control modes: vector V/F control, sensorless vector speed control,
   sensorless vector torque control, sensor vector speed control and sensor vector torque
   control .
  Advanced Vector Control Algorithm:
  *The optimized VF control and sensorless vector control is more stable at low speed,
   more powerful in the ability of low frequency torque output and with better dynamic
   response and both the sensorless vector and sensor vector mode support speed
   control and torque control.

Products Construction
AVF508 series Low Voltage VFDs are Used on Fan And Pumps


1, Load feature
  (1)  Both of them belong to fluid control.
  (2) If without VFD, the fluid is controlled by valve or baffles;
  (3) For less fluid required system, there will be more energy saving.
  (4) In theory, if the running frequency is H1, then
        Energy Saving = 1-(H1/50)3

2,  Requests for frequency inverters (VFD)
  (1) Soft start the motor, reduce the surge current.
  (2) VFD should work continuously without fault.
  (3) Speed tracking and start (flying start) function should be reliable.
  (4) In some systems, PID function is required.

3,  Real example
  In a hotel, there is an central air-conditioner, the cooling fan is one PCS of 15kW motor, in one year,
  it runs 4000h, 2000h with the air flow of 85%, 2000h with the air flow of 60%.
