Series connection
It is possible to connect multiple units of the same type
to a series connection if these rules are followed:
• No master-slave operation
• The grounds of the analogue interfaces MUST NOT
be connected to each other. This also applies for any
other signal on the analogue interfaces. If remote
control is required, it can be done using galvanic
isolation ampliers and by controlling all units in
parallel.
• Any load current leading conductor must be dimen
-
sioned for the maximum output current of the unit
with the highest nominal output current.
Parallel connection
Multiple units with identical output voltage and ide-
ally identical output current can be used in parallel
connection (master-slave or other) without any res-
trictions. For example, the master is equipped with a
digital interface card and the units are wired via their
analogue interfaces. Here the monitor outputs of the
master are connected to the set value inputs of the
rst slave etc.
Alternatively, all units can be equipped with a digital
interface card in order to supervise and control any
units seperately. Controlling the units with identical set
values is possible ny using broadcast messages.

and current:
