Multifunctional Three Phase Inverter VFD 2.5A-950A 380V Stable
Variable frequency drive 0.75kw-710kw VFD single phase Three Phase
Product Advantage
KD100 Excellent control performance
0.1s command acceleration and deceleration under rated load of motor
When the motor is switching over zero speed, there is no phase change and oscillation in the current, and the speed is not pulsating.
Bus voltage control is stable, deceleration without dynamic braking can also provide fast and reliable braking capability
Realize no tripping operation
Excellent current and voltage control technology, alternately accelerating and decelerating with 0.1s command, the inverter is stable without tripping operation
Strong overload capacity, continuous operation for 10s under 180% rated load condition, 1 minute continuous operation under 150% rated load condition
Low frequency and high torque stable operation under vector control
Unique power grid instantaneous power-down processing
