2.6.3 Parallel Connections

Figure 2-6 illustrates how modules can be paralleled to increase power dissipation. Modules
can be directly paralleled in CC, CR or CP mode. Modules cannot be paralleled in CV mode.
Each module will dissipate the power it has been programmed. For example, if two modules
are connected in parallel, one is programmed 10A, and another is 15A, the total current
drawn from the source is 25A. Restriction on number of parallel modules depends only on
total modules available in the multi-mainframe environment described in the next section.

2.6.4 Multi-Mainframe Connections

The Electronic Load system offers multi-mainframe synchronized connectivity for up to 4
mainframes. The user is allowed to connect either System Bus1 or System Bus2 port on rear
panel of a mainframe as input from previous mainframe, and use the remainder as output to
the next mainframe. For a systematic configuration, it is strongly recommended to connect 2
mainframes in the way as from System Bus1 on a mainframe to System Bus2 on the other
mainframe. Figure 2-7 indicates how to connect mainframe1 and mainframe2 along with
extend to mainframe3.
