PSM – Power System Module
Measurement bars for direct
connection without gateway to
the Rittal CMC III system. With a
PSM mounting kit, the measurement
bar may be vertically
mounted in a 2000 mm high
Rittal TS 8 or in the TS IT rack.
Display and monitoring of all
major output parameters is supported,
separated by phase and
infeed. An integral display provides
a local on-site display in
the rack.
Remote administration and network
connectivity are created via
the CMC III system.
