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.

AC Regenerative Systems are an ideal solution for:
  • High duty cycle cranes
  • Large cranes with multiple resistor banks for each motion
  • Severe duty, dusty, wet, or volatile environments

AC Regenerative Systems provide:
  • Energy efficiency
  • Cost savings - payback can be seen in the first year
  • Elimination of wiring for dynamic braking resistors

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.
