Parallel / Series Operation
This section describes the basic operations required to operate the
power supply in series or parallel. Operating the PSW series in
parallel increases the total power output of the power supply units.
When used in series, the total output voltage of the power supplies
can be increased.
The number of the power supplies that can be connected in series
or parallel depends on the model and the mode:
 Series Mode: 2 units maximum; 30V, 80V and 160V models only.
Parallel Mode: 3 units maximum
CAUTION
250V and 800V models do not support series
operation!
To use the power supplies in series or parallel, units must be used
in a Master-Slave configuration. In the master-slave configuration a
“master” power supply controls any other connected “slave”
power supplies.
