D31 Series General VFD

D31-Series Variable Drive
  • Removable protective labels are attached to the top of the plastic case for side-by-side installation.
  • High-performance vector control is realized by using flux linkage and velocity estimation technique
  • The wide voltage range is designed to ensure the adaptability of products to grid fluctuations. Before the converter reaches soft over-current, it can run with the current value limited by hardware to reduce the frequency converter’s over-current failure.
  • During deceleration, when the DC bus voltage exceeds the set value, the converter will be protected according to the over-voltage protection mode you choose.
  • Advanced independent air duct design, adapt to a variety of complex, harsh site environment.

D32 Series Compact VFD

D32-Series Variable Drive
  • Compact structure design, save installation space.
  • Clear terminal layout wiring identification, easy to install wide voltage range design.
  • Ensure the adaptability of products to power grid fluctuation.
  • Advanced independent air duct design, adapt to a variety of complex, harsh site ring.
