Power Supplies


Designs for Availability and Hazardous Locations

The fieldbus power supply provides power for the field devices and enables communication between the field devices and the control system via one common cable. It comes in two forms - as a Power Hub and as a Basic Power Supply.

The Power Hub consists of a motherboard and individual power supply modules. The modular design allows precise solutions for different applications and types of explosion protection. Customized host connections enable efficient and error free connection to various host systems. Power Hubs are available in three different models:


  High-Density Compact Universal
