Kikusui PWR401ML - Series operation

108 PWR-01
Series operation
Up to two PWR-01s whose output is less than 650 V can be connected in series. You cannot
perform master-slave series operation. The total of the output voltages of the two units is
applied to the load.
The voltage setting accuracy is the same as the accuracy of an individual unit.
Features
The functions of the PWR-01 during series operation are as follows:
Voltage display and current display
The voltage and current are displayed on unit 1 and unit 2. To calculate the total output volt-
age, add the voltages of unit 1 and unit 2.
You can switch the display so that it shows power. The power is displayed (p.34) on unit 1
and unit 2.
External control
This is available (p.83).
External monitoring
• External monitoring of the output voltage (VMON) (p.98)
You can monitor the output voltage of each unit.
To calculate the total output voltage, add the monitored values of unit 1 and unit 2.
• External monitoring of the output current (IMON) (p.98)
You can monitor the output current of each unit.
• Status monitors (p.99)
You can monitor the status of the following items from each unit: constant-voltage mode
(CV STATUS), constant-current mode (CC STATUS), output on, POWER switch on, and
alarms.
W ARNING
Series operation is not possible on the H type (PWR401H, PWR801H, PWR1201H). If
you do, the output will exceed the isolation voltage resulting in a dangerous condi-
tion.

During monitoring, be careful of shorts and electric shocks. When monitoring the out-
put voltage or output current during series operation, the electric potential of the
commons of unit 1’s monitor signal and unit 2’s monitor signal are different.
