The shock-hazard-protected vertical supply busbar accommodates up to seven plug-in modules over its height of 2000mm and thus offers up to 42 IEC320 or earth-contact sockets in the enclosure.
Rotating the plug-in modules by 180 degrees serves to contact one or other of the two feeds.
An additional feature of the active PSM system is the informative user interface.
A current measurement and a corresponding display has been integrated into the active PSM to enable monitoring of the instantaneous current load per socket module to minimise overloading the fused power distribution.
Each active PSM can be switched on and off by pushbutton.
This function can also be used in case of a system restart.
If several active PSM units are installed in one rack, simple bus-cable connections ensure that following a supply failure they are switched back on sequentially to prevent overloading of the power supply.
Rittal has incorporated the active PSM system into its CMC-TC monitoring concept allowing all operating parameters to be configured and managed remotely from a central administrator PC via http and/or SNMP.
Alarm messages are also generated automatically when the defined current limits are reached and can then be evaluated from a central control office. Request a free brochure from Rittal ...
