2.8 MULTIPLE UNIT CONFIGURATIONS
Parallel and series configurations of identical BOP units increase the rated voltage and current
range of the power supply. Up to two units (three units for model BOP 10-100GL) can be con-
nected in parallel to increase the current: I
MAX (one unit)
x N
P
= I
MAX (parallel combination)
where N
P
= number of units in parallel. Similarly, up to two units can be connected in series to increase the
voltage: E
MAX (one unit)
x N
S
= E
MAX (parallel combination)
where N
S
= number of units in series. For
configurations requiring more than two units in series or parallel, contact Kepco. Multiple unit
configurations require the appropriate Interconnection Kit (see Table 1-5).
For all multiple unit configurations the master reports the system output parameters: voltage and
current; the slaves display and send to the master their own main channel parameter: voltage
for series configurations or current for parallel configurations.
Additional hex nuts are provided in the interconnection kit for sufficient cable separation so they
can be oriented as needed to fit onto the terminal.
NOTE: Multiple unit configurations require that all individual units be properly calibrated. (Units
shipped from Kepco have been factory-calibrated.) If not, refer to Section 4 to calibrate
the individual units prior to connecting them in parallel or series. Using calibrated units
ensures that the multiple unit configuration is calibrated; calibrating the multiple unit
configuration is neither needed nor possible.
2.8.1 MULTIPLE UNIT CONNECTIONS
Before connecting the units in parallel or in series, turn off all units and remove any previous
interconnections between units as well as connections to the load
Refer to Table 2-2 and configure the top cover power up switches S1 through S3 of each unit for
the desired configuration master/slave, series/parallel (S2), GPIB address if desired (S1), and
additional settings (S3) as needed. Then turn on each unit for approximately 10 seconds to
allow the settings of S1, S2 and S3 to be stored.
Turn off the units, then proceed with the parallel or series connection. Figures 2-7 (local sens-
ing) and 2-8 (remote sensing) show the connections for three parallel-connected units; Figures
2-9 (local sensing) and 2-10 (remote sensing) show the connections for three series-connected
units. These figures allow other configurations, e.g., two parallel- or series-connected units to be
easily deduced. Consult factory for configurations requiring more than two units in series or par-
allel (three units in parallel for BOP 10-100GL).
CAUTION: For both parallel and series configurations, remove links between (COM S)
and (COM OUT) terminals of all slaves to prevent damage to the unit and
maintain system accuracy. Make sure to accurately follow Figures 2-7
through 2-10 for proper connection of the units.
The following connections are required.
• Power cables
• Sense connections (either local or remote)
• Interconnection cables and terminations required for parallel or series configurations are
supplied in the applicable Interconnection Kit (see Table 1-5 for part number).
