The medium voltage variable frequency drive is the fruit of a secondary development and design based on sophisticated AC60/AC80 platform. The medium voltage inverter is prominent with high performance and high reliability.

Voltage Rating of MV Variable Frequency Drive
660V (three-phase power) 7.5-630kW
1140V (three-phase power) 30-1000kW

Features of MV Variable Frequency Drive
1. High Reliability
a. using sophisticated AC60/AC80 platform for secondary development.
b. optimizing the layout and structure, to extend the life and improve the reliability of the electrical equipment.
c. the wiring of variable frequency drives that have powers above 93 KW goes from top down, optimizing the internal structure of control cabinet.
d. standard DC reactor is equipped on AC60 series above 160KW and AC80 series above 30KW. The reactor effectively reduces THDI, improves the input power factor, and protects your grid. DC reactor access terminal is reserved for the whole series.

2. Superior Environment Adaptability
a. standard frequency inverters have conformal coating. For occasions of excessive humidity or dust, protective strengthening measures are taken to ensure long-term stable operation in harsh environment.
b. duct isolation technology: sealed to be resistant to moisture and dust, easy to deal with harsh industrial environment.
c. better environment tolerance than imported variable frequency drive.

3. Powerful Communication Functions
a. master-slave communication by the use of international standard ModBus communication protocol. Users can realize centralized control via PC / PLC, PC, and the master drive in order to adapt to specific application requirements (set drive control command, modify operating frequency, modify relevant function code parameter, monitor working status and fault information of the inverter, etc.).
b. AC80 series supports fieldbus expansion and optional Profibus protocol.

4. Powerful Anti-Jamming Design
a. wide operating voltage range, with over-modulation technology to ensure load capacity in case of low-voltage.
b. the immunity to grid surge (lightning sensors), grid noise, and electrostatic, has reached harsh industrial-grade standard.
c. the control power and the control bus are separated; the power has its exclusive power source by using an isolated transformer; the control power is designed to have standard filter circuit.
