[INTRODUCTION] Q-5000 SERIES Hi-Performance Low-noise Mini Vector Inverter is a new-type mini-AC inverter but packed with high performance features for induction motors available from 0.4-2.2kw which is the ideal solution to variable speed. Q-5000 is featured for SPWM design which provides low noise and high start torque. The inverter is independent and used in 50/60Hz (±5% fluctuation is allowable). The current overload rating is 150% for 60 seconds, sensorless vector control and V/F control make this inverter more brilliant for most general applications. Q5000 is featu

[INTRODUCTION] 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. There are four control modes to select. Even without PG vector control, it can obtain a high torque and failure-free operation from a low speed at 1%; While with PG control, it can easily obtain high torque operation at 0 speed, which is the ideal choice for you to improve the quality and productivity.
