7-3. Serial Master-Slave Operation
In PS-A power supply units, only the same models can be used for serial master-slave operation. Do not use models
with different rated current for serial master-slave operation, even if their output voltage is the same. Doing so may
cause the unit to malfunction.
One unit should be configured as the serial master unit, and another unit as the slave unit.
Precautions for connecting the master unit and slave units:
・
DO NOT use OP-23P3 or OP-23P6. These cables are used for parallel
master-slave operation.
If OP-23P3 or OP-23P6 is used, the positive and negative outputs of the master
slave will short-circuit. This may cause the unit to malfunction.
・
If 2 PS-A power supply units are connected as shown in illustration above, the 2
units will perform serial master-slave operation, even if the master unit is set for
stand-alone. In this situation, double the amount set voltage will be output
from the units This may cause an accident or destroy the load. Be sure to
onfigure the master unit as the serial master unit.
