IMPULSE®•D+ HHP Regenerative Drive

AC Line Regenerative Control Systems

The IMPULSE•D+ HHP is a modular, regenerative inverter platform designed with reliability and serviceability in mind.

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.

Features & Benefits

Features and Benefits

AC Regenerative Systems are an ideal solution for:

  • High duty cycle cranes
  • Large cranes that benefit from eliminating resistor banks for each motion
  • Severe duty, dusty, wet, or volatile environments

AC Regenerative Systems provide:

  • Energy efficiency
  • Cost savings - power is recycled instead of wasted
  • Eliminate wiring and maintenance of dynamic braking resistors


The IMPULSE•D+ HHP is a high-performance Active Front End regeneration system in a fully assembled control panel. The Active Front End technology allows the IMPULSE•D+ HHP to minimize input current harmonics to facilitate IEEE 519 requirements and provide a consistent DC bus voltage for the connected VFDs. Multiple VFDs can be connected to the common DC bus. IMPULSE•D+ HHP is available as a fan-cooled control panel, with air conditioning and additional options available upon request. Combining the IMPULSE•D+ HHP with IMPULSE variable frequency drives will provide you with the most energy efficient, durable, and feature-rich crane control system available.
