Frequency inverter (75 - 1200 kW) | CHA100

1.Rectifier/Regenerative unit can feed regenerative energy back to gird. Compared to the classical braking method, this is more effective in energy saving.

2.Current harmonics on line side is little, and the power factor is close to 1(Full load).

3.Excellent performance of close loop vector control: Output torque is up to 200% at zero speed.

4.To simplify and maintain the system conveniently, power unit of Rectifier is the same with inverter''s in hardware configuration.

5.To work together with common DC bus, rectifier and inverter adopt completely independent control solution.

6.Power-up logic control, brake control, over-speed protection and start-up torque previous compensation which ensure that the crane runs safely and reliably.

7.Adopts Profibus-DP , Modbus and Ethernet.

8.Mater-slave control function fulfills power balance and speed synchronization of multi-motor application.

9.To control the system conveniently and decrease the costs, the 2nd control and switching function is available.

10.Control mode: Sensorless vector control, Vector control, V/F control

11.Abundant peripheral interface.

12.Double protection on system and units, time sequence control, guard protection control.

Application

1.Port Crane machinery: Quayside Container Crane, Ship loading cranes and ship unloaded, etc.

2.Mining machinery: mine hoist, Belt Conveyor, etc.

3.Metallurgical machinery: Multi-motor drive rolling mill, etc.

4.Foodstuff processing machinery and Pharmaceutical Machinery: Centrifuge, scouring machine, etc.

Optional accessory

Profibus-DP communication module.
