■ Overview SITOP modular SITOP modular SITOP modular
signalling module buffer module redundancy module
■ Application
Using the signalling module in
combination with a stabilized
SITOP modular power supply
unit, signals can be provided
on the operating status of the
power supply unit, and remote
switching ON/OFF of the unit
is possible; automatic contacting
with the power supply
unit.
With brief interruptions in the
power supply, the buffer module
in combination with a stabilized
SITOP modular power
supply unit can buffer the load
current without an interruption.
The buffer module is
wired in parallel with the output
of the power supply unit.
The redundancy module
serves to decouple two stabilized
SITOP modular power
supplies in parallel mode. If
one power supply fails, the
24 V is safely retained.
