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. • 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 • 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 5-100 HP, IMPULSE®»D+ units are available up to 450 HP, and IMPULSE®»D+ HHP units are suitable for uses up to 1,500 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. 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. *For higher voltage, contact Magnetek Material Handling

With our combination of extensive application experience and leading-edge products, Magnetek provides the ultimate solution for overhead motion control. APPLICATION DIAGRAM EXAMPLE IMPULSE Drive IMPULSE Drive IMPULSE Drive The IMPULSE'R is designed to provide a low-cost solution to add line regeneration to your overhead crane. It is as simple to operate and IMPULSE»R is sized identically to the connected variable frequency drive. The IMPULSE'R can be easily retrofitted to replace dynamic braking units and resistors on existing controls. DIAGRAM EXAMPLE For more information, contact Magnetek Material...
