Remote Programming
The master unit is programmed in the normal way to give remote control of the output
voltage or current of the parallel combination. See section 6.4.3. on remote programming.
N.B. The current measured by the master will be that proportion of the load current
supplied by the master. All units supply equal current and so the total current will be the
master current multiplied by the number of parallel units. Alternatively, the current
readings of the master and all the slaves can be summed (necessary if different models
are placed in parallel). This should be taken into account when programming current
limit settings or when working in constant current mode. The master output voltage will
be the voltage seen by the load.
6.4.5 Master-Slave Series Operation
WARNING - Hazardous voltages will be present when operating in this mode and the
appropriate precautions should be taken.
The power supplies can be connected in series for master-slave operation. When
connected together in this way, a higher total output is available than the maximum
output of each individual unit. In this mode the slave units follow the master, thus giving
a total output voltage equal to the output voltage of the master multiplied by the number
of units in series.
