• Can save 20%-50% energy of your motor; power range – 0.75-11 kW; input voltage – 1 phase AC, 220 V, 3 phase AC - 380 V, 460 V, 575 V, 660 V - (fluctuating – 15%); output voltage – 3 phases 220 V - 660 V; output frequency range - 0 - 800 hz
• Has protection of over-current, overheat, over-voltage, overload, less voltage and less load; central control module based on DSP (digital signal processing), realizes high-speed and perfect performance control
• Integrated V/F control, V/F+PG control; 3 produce ways of special voltage vector waveform; dead area compensation function, realize low frequency and big torque control; automatic slip compensation
