1.Q9000 Series Frequency inverter,VFD

2.Single phase,three phase inverter

3.12 months warranty

4.13 years experience

5.CE,ISO9001

Q9000 Series is a kind of high performance universal vector control inverter. Current vector technology and advanced modern control theory are used to provide more torque in operation at low speed and achieve high performance dynamic control. 

Product Feature:

1)power range:2.2KW-315KW

2)Perfect Current Vector Control

3)By means of simultaneously controlling the primary current and its phase, the magnetic field current and torque current can be controlled respectively and individually to obtain a smooth run, a speed control and torque control with high torque and high precision at a very low speed

4)Various Control Functions

PID control, slip compensation function, speed search, over/lower torque detection and energy-saving operation control function

5)Excellent Torque Characteristics

Even if without PG, a high torque of 150%/0.5Hz can be reached

6)Powerful Braking Function

Powerful braking function can be fulfilled with built-in braking units for the inverter below 15kw and external braking resistors for that above 15kw

7)Hi-efficiency Energy-saving control

Wonderful energy-saving function beyond imagination, the hi-efficiency energy-saving control reaches the maximum effect in theory

8)Low Noise Operation

High carrier frequency SPWM modulation type may greatly suppress the noise, which is especially suitable for the place with limitation for noise.

9)perfect Power Ultraharmonics Suppression Countermeasures

Built-in DC reactor for the purpose of improving power factors is equipped for all series of 55kw and above; DC reactor wiring terminal is reserved for the units below 55KW for your choice of DC reactor to reduce the interference of the ultraharmonics of power.
