Motor speed controller/ ac drive 380v/220v, three phase/ single phase, 50/60hz input, 0-400hz output.

1. Advanced vector control algorithm , combine accurate speed calculation and self learning of the motor parameter. It realize the accuracy control of motor speed and torque under no- speed sensor mode. V/f and svc can be selected .

2. Optimized space voltage vector pwm modulation technology, has over-modulation function, high voltage-utilization, low output harmonic, and it greatly improves the motorí»s stability and switching loss.

3. Good operation characteristic of low frequency, can realize 0.5hz/150% rated torque output which under no-speed sensor mode.

4. LCD and led double display keyboard, display digit and chinese , the user can operate easily.
