Using the power supply
Attention!
If one unit in parallel connection with Share Bus switches
the output off because of an error, the whole system will
not provide voltage. If one unit is switched off by the po-
wer switch, the whole system will be provide no voltage
for a short period of 3-10 seconds and then continue to
work.
In order to control the whole system remotely, it is sufficient to
control the master via its analog or digital interface. When rea-
ding actual values, the voltage monitor value will represent the
overall system voltage, but the current monitor only the output
current of the master.
11.1.3 Mixed connections
Mixed connections are parallel and series connections within
one system. It is possible to do so, but we advise as follows:
First do the parallel connections, for example 3 units with 65V
and 10A each. Then do the series connection (same three units
again) in order to gain, for example, a 130V and 30A system.
If running high currents, it is advised to put the load in the middle
of parallely connected units, if an odd number.
