Frequency inverter from professional manufacturer POWTRAN technology.

We can produce different range of voltage frequency inverter.

The model of our frequency inverter is PI7550 series, PI7600 series, PI7800 series and PI8000 series.

 Main technical features of frequency inverter:

1)POWTRAN frequency inverter power range: 0.75~600KW

2) POWTRAN frequency inverter voltage: 3AC 220/380/440//575/690V -15%~15%.

3) Output frequency: 0.00 ~ 800.00Hz
4).Central control module based on DSP,realizes high-speed and high performance control.

5).Integrate V/F control,V/F+PG control,vector+PG control.

6).3 space voltage vector waveform produce methods.

7).Dead compensate function,realize low frequency and large output torque control.

8).Frequency inverter has automatic slip compensate.

9).At most 7 steps speed control and 8 steps acceleration control can be realized.

10).6 programmable  output control terminals.

11).Internal PID function,realize high performance closed loop control.

12).can add PID regulate DC braking system to frequency inverter.

13).Speed pursue starting and restart after momentary power loss.

14).Forced communicated function ,support standard RS485 and Can Bus,supply remote keyboard control function.

15).Special converse module (IGBT) temperature control function,adjustable fan control,timely reduce motor noise and temperature.

16).High-efficient faults inquiry and record function ,conveniently obviate the fault.

17).paramater protection function is our frequency inverter special point.

18).Unique design,make frequency converter least pollution to the power.

19).Outstanding behave 3-phase AC synchronous motor of permanent magnetism control.

20) Control mode: Vector control with PG (VC), sensorless vector control (SVC), V/F control
