Beckhoff is expanding its MX-System portfolio for automation without control cabinets to include powerful power supply modules for motion and robotics applications. These systems often include 48 V motion components, for which the MX-System portfolio now offers four variants of a 48 V / 40 A power supply.
In line with the basic principle of the MX-System, the new 48 V power supplies are plugged onto a baseplate and supplied with the primary voltage via the standardized system interface without manual wiring. This can be either the 3-phase mains voltage or the 600 V DC voltage of the drive system. Via the second MX-System interface, the power supplies – like all MX-System function modules – become participants in the EtherCAT network. This data interface also offers the possibility of feeding the 48 V voltage into the baseplate. In this case, both the 48 V DC and 24 V DC can be used by the corresponding function modules.
The most common use cases for the new power supply modules are motion applications. Another special feature is the ability of the power supplies to feed regenerative energy directly back into the machine’s supply network, such as that generated while the servomotors are braking. This eliminates the need for additional external braking resistors.
The new 48 V/40 A power supply modules from MX-System are available in versions for the AMI8100 integrated servo drives, the XTS intelligent transport system, and the Atro modular industrial robot, among others.
