Beckhoff Automation MX–System power supply modules

Beckhoff Automation has announced 48 V, 40 A power supply modules for its cabinet-free MX–System range.

The 48 VDC power supplies are plugged onto a baseplate and supplied with the primary voltage via the standardised system interface without manual wiring. The power supplies become participants in the EtherCAT network via the second MX-System interface. This data interface also offers the possibility of feeding the 48 V supply into the baseplate. In this case, both 48 VDC and 24 VDC can be used by the corresponding function modules.

The MX-System range offers function modules that provide 48 V as power voltage for servo drives and stepper motors. Existing 10 and 20 A power supply modules feed exclusively into the backplane, while the 40 A variants are designed so that 48 VDC devices can also be directly attached via connectors on the front of the function module. Four versions are available: a module variant with M12 connectors for attaching AMI8100 distributed servo drives; a version with two B23 connectors for attaching feed segments of the Beckhoff XTS transport system; a module for connecting a base module of the ATRO modular industrial robot; and a variant without connectors for direct line connection that feeds exclusively into the backplane.

Several power supplies can be connected to a baseplate and operated in parallel to balance peak loads. The power supplies also have the ability to feed regenerative energy directly back into the machine’s supply network, such as that generated while the servomotors are braking.
