Magnetek, Inc., a supplier of digital power and motion control systems for the material handling industry, announces the introduction of high performance AC Line Regenerative Systems that save customers energy, time and money. 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 by 40-45%. They eliminate the need for dynamic braking resistors, and are an ideal solution for high duty cycle crane applications.

“AC Line regeneration products capture the regenerative energy which would normally be dissipated by resistors and puts that energy back on the grid. This regeneration reduces a company’s total energy usage and improves overall facility efficiency by eliminating energy waste.  Heat that was previously produced by dumping excess power into resistor banks is also eliminated,” said Aaron Kureck, Magnetek Product & Development Director. “By improving the operating efficiency of their overhead cranes with these systems, some users with high duty cycle applications may recoup the cost of the regenerative drive in the first year.”

Two unit types are available to fit a variety of application needs. IMPULSE^®•R units are available with ratings from 5–100 HP, while the IMPULSE^®•D+ HHP modular, regenerative inverter platform is suitable for applications beyond 200 HP. They can be combined with the Magnetek’s IMPULSE^®•G+ or VG+ Series 4 adjustable frequency drives or retrofitted to the company’s IMPULSE^®•G+ or VG+ Series 3 drives and sized to fit the expected regenerative need.
