ALPHA6810 variable frequency inverter

ALPHA6800 variable frequency drive works intelligently in the injection cycles. The motor speed is controlled synchronously with the tracking of pressure and flow, which is equivalent to using a variable pump instead of the actual fixed-displacement pump. And the original hydraulic system works adaptively to the machine running power, eliminating the energy loss caused by high-pressure overflow in previous system. Furthermore, the VariableFrequency Drive makes the motor stop running under non-action state (Mainly the cooling state) thus enlarges the energy saving space and reduces the running noise as well as machine wear and temperature-rise. This series of inverter perfectly combines the injection machine and the asynchronous servo controller's advantages of rapid dynamic response and strong instantaneous over-current ability. Because of this, the energy saving of oil pump is 25%~70%, and hydraulic oil extends its lifetime to 3 years.

1. Wide input voltage range: 304~456V

2.Strong over-load capacity; protection to 250% instantaneous over-current

3. Dual analog input (0~1A); multiple selection modes

4. Rapid dynamic response ensures the production efficiency.

5. Built-in switching of servo and bypass (Cabinet integration); more reliable running

6. Servo/bypass switching control mode doesn't need the modification of injection related parameters after switching.

7. Soft start and tracking running reduce machine wear and extend lifetime of injection machine.

8. Pass EMC testing; no interference to original injection control system

9. Easy installation and debugging, free of alternation to original oil pump circuit
10. Retain the original injection control mode and its oil circuit

11. Optimal curve runs adaptively to the properties of injection oil circuit

12. Keep original injection techniques and its work efficiency

13. Runs synchronously with injection machine to extend machine lifetime without adjustment

14. User-defined control curves satisfy all kinds of injection techniques.

15. Direct proportional valve signal input; no transfer process

16. Energy saving rate varies among 25%~75% in different injection techniques.

17. Magnificent reduced heating; stable oil temperature; save higher than 30% cooling water

18. Extend sealants lifetime; reduce stoppage for maintenance; save large amount of maintenance fee
