Group Unit Mode
Background
The Group Unit menu allows load modules of the
same type and rating to be configured as a single
unit when used in parallel. This saves the hassle of
configuring each channel individually.
Group Unit is only supported under CC and CR
mode.
Group Unit has three configuration settings: Total
Unit, Group Mode and Display Mode.
Total Unit
This configuration setting sets the number units
that are to be used in parallel and enables or
disables the Total Unit mode.
Group Mode
The Group Mode setting determines how the
Current Levels/Resistance Values are set when
used in parallel. There are two settings: Para and
Sync.
The Para setting allows the all the parallelized load
modules to be operated as a single large load
module.
Sync mode allows the settings of a single unit to be
synchronized across all the other parallelized load
modules.
CC Example
Consider 3 load modules set to CC mode in
Parallel.
In CC mode the total current for all units is the
sum of each unit.

Total
For example, to set a total load current of 90A, the
Current Level setting in Para mode would be 90A,
whilst it would be 30A in Sync mode.
