4.7 Parallel Operation
When there is insufficient power or current rating on the electronic load module, two or more
electronic load modules can be paralleled to operate as one unit. A parallel connection can
extend the electronic load module to a higher power and current rating. In such a case, the
total load current and power is equal to the sum of the two (or more) load modules.
CAUTION:
Only channels with identical voltage polarity rating should be parallel
connected.
