7.6
Parallel Operation
It is possible to operate load modules in parallel if the power and/or current capability of a
single load module is not sufficient.
7.6.1
Parallel Mode Connection
The positive and negative outputs of the power supply must be connected individually to
each load module’s input as shown in Figure 7-7 below. The setting is made at each
individual load module. The total load current is the sum of the load currents being taken by
each module.

7.6.2
Allowable Operating Modes
It is permitted to operate 4 series load modules with different voltage, current and power
ratings to sink in parallel. For example the loads modules shown in Figure 7-7 could be a
mixture of 42L0860, 41L0630, 42L0824, and 41D1020.
While in static mode, the load modules can be set to operate in CC, CR or CP mode.
7.6.3
Exceptions
1.
Parallel operation in DYNAMIC mode is not allowed.
2.
Parallel operation in CV mode is not possible.
7.7
Series Operation
Series operation of dc load modules to achieve higher voltage ranges than supported by an
individual load module is
NOT
allowed under any circumstance.
