Note
Parallel connections
Parallel connection can be applied between same model modules to increase
current and power dissipation, but it can't be applied between different modules.
Modules can be paralleled in CC/CR mode, but can't be in CV mode. Each
module will dissipate the power it has been programmed for. For example, after
being paralleled, two single channel modules (80V/40A/300W) can dissipate up
to 80V/80A/600W. The following picture 1-7 illustrates the paralleled connection
of two same models for increased power dissipation.
IT8700P+ series modules support master-slave parallel connection, see
Parallel Function
For safety requirements, load wires between the electronic load and the object to be
measured should be heavy enough not to overheat while carrying the short-circuit output
current.
To prevent shock hazard, you must install the terminal cover correctly after wiring. Each
terminal can carry up to 30A current, double-terminal connection is needed when the
input current if more than 30A. (Double-terminal connection refers to the above picture.)
