Cost-efficient and trouble-free operation with AFE
Emotron Active Front End drives are available in two versions: Low harmonic drives and Regenerative drives. Both are based on standard Emotron AC drives, offering the same reliability, easy handling and advanced functionality. The drives are delivered as complete solutions in IP54 classified cabinets.
Emotron AFE drives produce extremely low harmonic distortions. They provide genuine unity power factor, and offer the possibility of reactive power compensation. The drives are nonsensitive to voltage dips or harmonics from other equipment. Voltage boosting assures full motor power in case of mains voltage fluctuations.
Low harmonic distortions
Emotron Low harmonic drives produce typically less than THDI 5% compared to 30-50% in conven-tional drives, thereby fulfilling the IEEE-519 standard. Reduced power losses eliminate the need to over dimension cables and transformers. Lower distortions also cause fewer malfunctions in other electronic equipment.
Emotron Regenerative drives, in addition to low harmonic distortions, offer considerable energy savings by feeding the braking energy back to the mains in applications such as cranes and centrifuges. The drives are rated for four quadrant operation with 100% power in both directions ensuring continuous full braking power.
