 This procedure is continued until load current triggers current
regulating at the output with the lowest voltage setting when
the setpoint value for cumulative current is reached.
 This output maintains constant load current until the load
resistor is short-circuited.
Figure 5.9.1 b U/I Diagram for Direct Parallel Connection
Notes:
 Slightly varying voltages occur at the individual outputs as a
result of setting tolerances.
In the event of larger voltage differences, an electronic sink is
activated at the outputs with lower voltage settings.
The sink attempts – in some cases in pulse mode – to reach the
lower voltage value.
Neither the KONSTANTERs nor the power consumer are
damaged as a result.
If problems occur with measurement of load current, the
KONSTANTERs should be linked by means of master-slave
parallel connection (see also chapter 5.9.2).
 The outputs can be activated and deactivated commonly by
connecting the SIG1 outputs to the TRG inputs (see also chapter
5.9.2).
