With the 120-kW module for ACOPOSmulti servo drives, B&R Industrial Automation provides its customers with inverters and power supply modules with maximum rated current values up to 165 A. The modules are offered for cold plate and feed-through mounting, and also have two open slots that allow the use of various ACOPOSmulti plug-in cards. Thanks to integrated PFC (Power Factor Correction), startup current values are reduced by up to 60 percent, which minimizes wire cross sections and the size of the fuses or circuit breakers required, the company explains. The stabilized DC bus allows motors to be operated with identical characteristics all over the world, and eliminates the need for upstream transformers. The ability to implement power regeneration results in energy savings of up to 50 percent, the company says, because brake energy is actively fed back to the mains instead of being converted to heat.
