- Series multi-level cell structure,can be very low input & output harmonic component；
- High price-performance, high-power volume ratio, for example, the 1500 KVA frequency inverter include the length of 3800 mm；
- High-power direct-drive high-voltage induction motor and synchronous motor；
- have no effect on the motor torque characteristics, not bring additional wear and tear. Starting can greatly improve performance, starting torque big, starting current small, start-up to eliminate the damage caused by the current, to eliminate starting current excessive impact on the grid；
- The main section and power unit through the fiber data transmission, data, communications high-speed, anti-electromagnetic interference ability, can be isolated high-voltage；
-With V / F (V / Hz) control and vector control mode ；
- Universal device built-in PID, without external control equipment to achieve closed-loop operation, such as: Constant pressure control。
- Standard RS485 and RS232 communication interface；
- Standard analog input and output, including multi-channel 4-20 mA interface, 16 isolated digital inputs, 16 relay digital output contacts passive, easy to expand system；
- Button operation and the scene of the instrument, even if touch-screen failure, can control the frequency devices。
- Many Motors parallel operation, unlimited tied number of motor within the inverter's limits of capacity, ；
- In all the speed range, maintain a high power factor running at 20% -100% of the load, power factor greater than 0.95；
- Long lines connecting motor output, the output dv / dt is small so that the output cables can extend up to several kilometers；
- On the touch-screen with the chinese windows interface, you can view the records, set parameters and do on-site operation；
-Incident record function ；
- Load management functions, provide historical data and load curve；
- Strong overload capability.Within the allowed temperature range,the device allow long-term 1.1times overload operation,rated on 1.25 times and 60s.When running for 1.25-1.5 times,start time-bound implementation of anti-overload protection,the device will not stop working.When more than 1.5 times,the current operation will stop.
-Wide input voltage range, short-term bear 30 percent of the voltage landing. long running in 90% -115% input voltage range。
