WST9000(0.75-3KW) Winston 0.75kw-3kw single phase Variable-frequency drive frequency converter inverter

1. standard functions maximum frequency

2. Carrier frequency 0.5-16kHz the carrier frequency is automatically adjusted based on the load features.

   Analog setting: maximum frequency 0.025%.

4. Control mode: V/F control

5. Startup torque: 150%

6. Speed range: 1:50

7. Speed stability accuracy: 1%

                                      P type:60s for 130% of the rated current.

9. Torque boost: fixed boost,Customized boost 0.1%-30.0%

10. V/F curve: straight_line V/F curve,multi_point V/F curve,Square V/F curve

11. Ramp mode: straight_line ramp,S_curve ramp two groups of acceleration /deceleration time with the range of 0.00-300.0s(m)

                         braking time: 0.0-36.0s,

                         braking action current value:0.0%-100.0%

                           JOG frequency range：0.00Hz to maximum frequency JOG acceleration/deceleration time 0.00-300.0s

14. Simple PLC,multi_speed running: it implements up to 8 speeds via the simple PLC function or combination of DI terminal states

15. Built_in PID: it implements the closed_loop process control system easily.

16. Auto voltage regulation(AVR): it can keep constant of output voltage automatically when the mains voltage changes.

17. Over current stall control: the current is limited automatically during the running so as to avoid frequency tripping due to over current.

18. Rapid current limit: it decreases the over current faults to the minimum and ensures normal running of theAC drive.
