Product features compact structure and excellent performance

Wide voltage design in line with international standards

Meet the needs of 380-480V three-phase power grids including Europe, North America, India, etc.

High-performance vector control to improve equipment accuracy

The maximum output frequency under vector control is up to 500Hz, which can achieve high-precision speed output within 10 times the field weakening speed range.

Low speed and large torque (high starting torque)

In the closed-loop vector mode, the linearity deviation of the torque line is within 3%, the torque output is stable, the low-frequency torque is large, and the stable load-carrying operation at ultra-low speed 0.01Hz can be realized. The torque mode and the speed mode can be easily switched , Complete DC braking circuit scheme.

Independent air duct design

The independent air duct design can effectively prevent dust from entering the inverter and cause short-circuit failures and improve reliability; the use of long-life cooling fans with large air volume can effectively reduce the temperature rise of the inverter and ensure the reliable and stable operation of the inverter.

Speed start

It can avoid over-current faults caused by direct start and realize a smooth start; it can reduce the impact of instantaneous power failure on production; it can reduce the impact on the power grid.

Intelligent energy saving function

Through the voltage flux vector algorithm, the closed-loop control of the output voltage is realized; when the motor torque requirement is low, the excitation current is reduced according to the load current; the motor efficiency is maximized; the motor loss is reduced, and the energy loss is reduced.

Overcurrent and overvoltage suppression protection

Through real-time monitoring of the load current during operation, it is automatically limited to not exceed the set overcurrent suppression point to prevent fault tripping caused by excessive current. This function is especially suitable for some loads with large inertia or severe changes.

Strong overload capacity

60s at 150%, 10s at 180%, 0.5s at 200%; overload protection is durable.
