5-2 Parallel and Series Operation PAS SERIES
5.1 Master-Slave Series Operation
• Master-slave series operation is not possible on the
320 V and 500 V models. If connected in series, the
output voltage will exceed the isolation voltage creat-
ing a dangerous condition.
5.1.1 Functions during Master-Slave Series Opera-
tion
The functions of the unit during master-slave series operation are
described below.
Voltage display and current display
As shown in Fig.5-1, the current is displayed only on the master unit,
and the voltage is displayed on each unit. For the total output voltage,
sum the voltages of the master and slave units.
Fig.5-1 Panel display during series operation
• The power display can be switched only on the master unit.
However, the power of the entire system cannot be displayed.
Remote sensing
Remote sensing function cannot be used during master-slave series
operation.
