Bachmann PSI135 Power Supply Module for backplane isolated

Power supply modules type PSI135 feed the backplane

and the internal supply sections of plugged modules. The

integrated galvanic isolation decouples disturbances and

separates supply groups strictly. Up to 4 PSI135 modules

can be operated simultaneously on one backplane, providing

supply redundancy in the event of a primary supply

or infrastructure failure. The remaining load is distributed

evenly on the unaffected modules. The devices measure all

relevant quantities of supply and load circuit automatically,

aggregate them to meaningful diagnostic information on

the application interface as well as visual indication.
