Product Introduction:
This series inverter can return the load inertial energy to grid with function of regeneration and brake. This product is the high performance green energy product which is suitable for the position energy and environment demand heavy load.Product takes PWM IGBT inverter technology, to double control of the inverter and feedback, power factor close to 1, this is the real four quadrant running.
Application Fields:
- Container crane, Gantry crane, Ship loader/unloader and similar equipment at port;
- Large-tonnage bridge cranes;
- Large power mining hoist;
- Centrifugal casting machine, Large punch in metallurgy;
- Oil pumps and large reciprocating machinery.
Technology Advantages:
1. Inverter front end take the IGBT PWM inverter technology and improved SVPWM control,powor close to 1;
2. Excellent close loop vectoer factr control,increase the system stability;
3. Outstanding torque control performance to meet users precise control demand;
4. Integration of V/F,without PG(SVC),with PG(VC)in one product to meet different users demand;
5. Power cells take the compact design modular for easy operation and maintenance.
