PRO-M = Power-Reliable-Optimized
The perfectly reliable power supply for automation
technology.
The ten different versions for the 24V-DC power supply
all feature a solid but thin metal housing which enables
them to be installed without any side gaps. This results
in less space required on the mounting rail. Wide range
of AC/DC inputs and a wide temperature range enable
them to be used anywhere. Because of its high efficiency,
resistance to overloads and high power reserves, the PRO-
M is a trusted power supply for use in any application.
The three-phase PRO-M power supply modules continue
to function reliably when one phase fails (i.e., in two-
phase mode).
