Fully integrated, regenerative AC drives in a 7.5 to 125 horsepower range extend the range of motor-control solutions provided through the vendor’s ACS800 drive family.
The new units, model number ACS800-U11, are designed for operating voltages of 208-240VAC and 380-480VAC. The regenerative drives incorporate an active supply unit rather than the passive diode supply used in conventional drives, and also have a built-in LCL filter to eliminate high-frequency harmonics. “Regenerative drives offer two significant advantages. They can recover energy from a process and feed it back into the network, and they help to maintain power-supply quality, thanks to their superior harmonic performance,” says Mike Vallier, product line manager. The regenerative drives are delivered with the vendor’s start-up assistant, designed to provide menu-driven help to make setting parameters intuitive and easy.
