Regenerative drives Technical catalogue

Cost-efficient and trouble-free operation with Emotron AFE Emotron Active Front End drives will save costs and improve reliability in your process. They are available in two versions: Low harmonic drives and Regenerative drives. Both are based on standard Emotron AC drives, providing the same benefits in reliability, easy handling and advanced functionality, as well a wide range of options. Emotron AFE units are delivered as complete solutions in IP54 classified cabinets. Setup is easy thanks to plug-and-play functionality to the mains supply. Trouble-free operation State-of-the-art technology...

Network friendly low harmonic drives The demand for network friendly electronic equipment is continuously increasing. Low harmonic drives are the answer to this challenge, improving reliability and reducing investment costs in applications such as pumps and fans in the mining, marine and process industries. Extremely low harmonic distortions Emotron Low harmonic drives produce typically less than THDI 5% compared to 30-50% in conventional drives, thereby fulfilling the IEEE-519 standard. Reduced power losses eliminate the need to overdimension cables and transformers. Lower distortions also cause...

Energy saving regenerative drives Emotron Regenerative drives, in addition to low harmonics, offer energy savings in applications with frequent braking, such as cranes, centrifuges, test benches, winders and ski lifts. They provide robust yet fast and smooth control, and allow uninterrupted power flow to and from the mains supply. Regenerative units can also be supplied as DC-bus feeder units. Regenerative braking Emotron Regenerative drives offer the option of feeding braking energy back to the mains instead of dissipating it via brake resistors. This will save considerable energy costs as well...

Environmental conditions Operation at higher temperatures All Emotron AFE units are made for operation at maximum of 40°C ambient temperature. However it is possible to use the AFE units at higher temperatures with some loss in performance, using derating. Derating: - 2,5 % per degree Celsius. Maximum is +5 °C (45 °C).
