Controls and VFD's

Variable Frequency Drives

Electromotive Systems' IMPULSE Series 3 Crane Controls incorporate the latest in advanced control technology to maximize the performance and safety of your material handling system. Yet there's no need to learn complicated new programming. The Series 3 has been designed to mirror the programming of the IMPULSE Series 2 product line, making the move to series 3 an easy trasition.

Braking Resistors

Magnetek Variable Frequency Drives (VFD) are used on many cranes, creating the need for a reliable, proven Dynamic Braking Resistors that can be delivered quickly, completely assembled, and ready for convenient installation at the job-site. Dynamic Braking Resistors are used with VFD’s to produce a braking torque in the motor during overhauling conditions. The dynamic braking resistor is connected across the DC bus and will see voltages as high as 800 volts.
