Parallel connections
Two or more power supplies being capable of the CV/CC
automatic crossover operation can be connected in parallel
to obtain a total output current greater than that available
from one power supply. The total output current is the sum
of the output currents of the individual power supplies. The
output of each power supply can be set separately. The
output voltage controls of one power supply should be set to
the desired output voltage; the other power supply should be
set for a slightly higher output voltage. The supply with the
higher output voltage setting will deliver its constant current
output, and drop its output voltage until it equals the output
of the other supply, and the other supply will remain in the
constant voltage operation and only deliver that fraction of
its rated output current which is necessary to fulfill the
total load demand.
