PBZ

Parallel Operation

You can magnify the PBZ’s output current by connecting multiple units in parallel. In parallel
operation, one unit is the master unit, and all other units connected in parallel are slave units.
The master and slave units must all be the same model. Parallel operation of all the units is
controlled from the master unit. Just like operating a single PBZ, you can use all the features
that were explained in chapters 2 and 3. However, there are some special features and
operations that can only be used during parallel operation. These features and operations are
explained below. All features are set up from the master unit.

●

You must use the parallel operation kit (sold separately) when you perform parallel
operation with two units

By using the parallel operation kit, you can perform parallel operation with two PBZ units (the
master unit and one additional slave unit). The parallel operation kit does not support parallel
operation with three to five units (including the master unit). If you want to perform parallel
operation with more than two PBZ units total, Contact your Kikusui agent or distributor.

Voltage display and current display

The master unit’s ammeter displays the sum of the currents from all the connected PBZ units.
The voltmeter displays the voltage that you specified. Slave units display their own output
current.

Overcurrent protection

Overcurrent protection is configured from the master unit. The activation points take into
account the number of units that are connected in parallel operation.

External monitoring

•

External monitoring of the output current (I MON)

On the master unit, the output voltage is proportional to the sum of the currents produced
by all units operating in parallel. For an output current of 0 A to ±(the rated value x the
number of units in parallel operation), a voltage of 0 V to approximately ±2 V is generated.

On slave units, the output voltage is proportional to the current that the slave unit itself
generates. For an output current of 0 A to ±the rated value, a voltage of 0 V to
approximately ±2 V is generated.

•

Status monitoring (J1 connector)

From the master unit, you can monitor the status of CV mode (CV STATUS), CC mode
(CC STATUS), output-on (OUTPUT ON STATUS), and alarm generation (ALARM
STATUS).

From a slave unit, you can monitor the status of output-on (OUTPUT ON STATUS) and
alarm generation (ALARM STATUS).

Using the Parallel Operation Kit

p. 168 

The parallel operation kit PK01-PBZ, PK02-PBZ and PK03-PBZ are designed to connect two
PBZs (one master unit and one slave unit) in parallel. The PK01-PBZ is a kit designed to be
used on a bench top. With this kit, the side panels of two PBZs are connected with dedicated
brackets, and the OUTPUT terminals are connected together with dedicated connection bars.
The PK02-PBZ (for inch racks) and the PK03-PBZ (for millimeter racks) are kits designed to
be used on a rack. With this kit, two PBZs are rack mounted, and the OUTPUT terminals are
connected together with dedicated connection bars.
