company in China. We adopt SPWM, sensorless vector control and
vector and torque control technology in our VFD series inverters,
which has reached the international advanced standard. The products
can directly replace and be equivalent of Europe and the United
States, Japan and other brands, providing customers with a powerful
technical support. We have achieved popularity and qualification in
VFD industry. Quality is the life of enterprise.
What We Can Provide For You?
High Performance Variable Frequency Inverter With Nice Features.
1.Independent air dust design, effectively preventing dust entering
inverter, causing shor-circuit and other faults and improving
reliability. Use bigger air volume and long life cooling fan
effectively reduces the internal temperature rise of the inverter
and ensures reliable and stable operation of inverter.
2.High speed accurancy and wide speed range.High speed accuracy and
wide speed range Steady speed accuracy: ±0.5% (SVC), ±0.02% (VC)
Speed range: 1:200 (SVC), 1:1000 (VC) Heavy load overload
capability: 110% rated current for long-term stable operation 150%
rated current for 1 minute 180% rated current 10s
3.High torque in low speed, fast response Load capacity in low
speed: VF: 180%@0.50Hz SVC: 180%@0.25Hz VC: 200%@0.00Hz
