AC LINE REGENERATIVE SYSTEMS Magnetek’s high performance AC Line Regenerative Systems are ideal for adjustable speed applications that include a high demand braking cycle. These industrial grade units take surplus regenerative energy from the motor and return it to the AC power source, reducing total energy consumption and improving energy efficiency. IMPULSE®•D+, IMPULSE®•D+ HHP, & IMPULSE®•R+ AC REGENERATIVE SYSTEMS ARE AN IDEAL SOLUTION FOR • igh duty cycle cranes H • arge cranes with multiple resistor banks for each motion L • Severe duty, dusty, wet, or volatile environments AC REGENERATIVE SYSTEMS PROVIDE • Energy efficiency • ost savings – payback can be seen in the first year C • limination of wiring for dynamic braking resistors E • Elimination of dynamic braking resistors’ maintenance Three different unit types are available to fit your application needs. IMPULSE®•R+ units are available with ratings from 5–400 HP, IMPULSE®•D+ units are available up to 830 HP, and IMPULSE®•D+ HHP units are suitable for uses up to 2,000 HP. They can be combined with IMPULSE®•G+ or VG+ Series 3 or 4 adjustable frequency drives and sized to fit the expected regenerative need. IMPULSE•D+ IMPULSE•R+ The IMPULSE•D+ is a high-performance Active Front End Regeneration Unit in a chassis drive layout. The Active Front End technology allows the IMPULSE•D+ to minimize line harmonics below IEEE 519 requirements and regulate a consistent DC bus voltage. Combining the IMPULSE•D+ with IMPULSE•G+ and VG+ Series 4 variable frequency drives provides you with the most energy efficient, durable, and feature-rich crane control system available. The IMPULSE•D+ HHP is a modular, regenerative inverter platform designed with reliability and serviceability in mind. It utilizes Active Front End (AFE) technology to maximize crane control efficiencies with extremely low line harmonics. IMPULSE•D+ HHP units exceed the requirements defined by IEEE 519 and the common bus architecture allows the drives to share energy. Enclosures are offered with open chassis, NEMA 1, forced air cooled, or air conditioned options.
