powerful high performance frequency converter

Power range

Voltage : 11402300V Single-unit power : 75630kW

Application area

Suitable for the high-end application area with big inertia load, potential load, high precision, fast response and etc.

Features of system structure

• Traditional 3 level PWM structure of neutral character for inverting
• Simple circuit structure with less component and higher reliability. Higher voltage output can be realized without serial connect of power components
• Output voltage wave form is more like sine wave. High harmonic of voltage is less
• dv/dt is smaller, no special requirements to motors' insulate performance
• Small size and low cost ...................(AC drive)(motor drive,motor control)(VFD).............

Performance Features

• Function of vector control, V/F control switching, Choose freely according to the using requirement form the 4 mode: V/F control, V/F with PG, seedless sensor vector control, vector control with PG.
• Auto discern motor parameters, adapt fast to the load
• High rating torque output of open loop low speed. Speed control reaches to 100: 1
• Total torque control of close loop zero speed. Control range reaches to 1000: 1
• Advance auto adjusting function to make motor work in the best condition
• Energy saving control function makes motor work in best condition, with PID adjuster, total automated operation is realized.
• Sliding compensation makes motor work stable
• Internal automated torque compensation function makes motor work accurately.
• Torque control function makes motor work with constant torque
• Auto reset when malfunction
• LCD panel with user friendly interface, multiple parameters can be adjusted online and copied, convenient for use
• Minimal pollution to electric network, high efficiency
