EV8 Variable
Speed Drive
Key Benefits
EV8 series variable speed drives are designed to control 415V or 690V large kW motors up to 1500kW. These high-performance drives are suitable for dusty industrial environments because they are supplied in IP54 enclosures complete with input and output filters as standard. Active Front End (AFE) technology is employed in the series to overcome and almost eliminate problems caused by harmonics.
Advantages
- Suitable for speed control of large kW LV motors
- Active front end reduces supply line harmonics
- Improves the power factor to near unity (p.f. > 0.99)
- IP54 cubicle is designed to protect against harmful deposits of dust
- Motor energy of high inertia loads is returned back to the power mains with the high dynamic performance
- Eliminates costly braking circuits and bulky resistance
- Extensive features for heavy-duty industrial speed control applications
