Features:
Rich features
Independent series mode
The MV generated by the single-phase low-voltage power supply in series uses the phase difference of the multi-winding transformer to improve the input quality (no input filter is required), and the multi-stage PWM generates a sinusoidal output waveform without the need for an output filter, which greatly reduces the effect of the reflected voltage generated by the long-distance cable connected to the motor. The number of independent power supplies required is the same as the number of power supply units, and the composition is simple and easy to install modules (power supply units).
Power factor control of the power supply
High power factor & stable control performance in any speed range.
High efficiency
With a conversion efficiency of 98% or even higher, the efficiency of the whole drive system: 96-97%.
miniaturization
The optimized internal design allows for a better understanding of the thermal movement inside the panel.
Built-in unit bypass
The self-diagnostic bypass technology of the power unit, any power of the high-voltage inverter connected in series during operation
In the event of a unit failure, the faulty power unit is automatically bypassed, and this function can be set automatically/manually as required.
Sensorless vector control
Powerful sensorless right-amount algorithm for extremely high torque performance and precise speed control at low speeds.
