When connecting the PSU power supplies in
parallel, up to 4 units can be used in parallel and
all units must be of the same model with similar
output settings.
To use the power supplies in 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. In order for the master unit to
control the slave units, the master unit must use
the analog control connector to control the slave
units.
When using the Analog Control Connector, the
connector must be wired correctly between the
master and each of the slave units. For the
complete connector pin assignment, see page 118,
or alternatively, the PSU-01C, PSU-02C and the
PSU-03C cables can be used to connect a master to
unit to 1, 2 or 3 slave units, respectively.
