Setting Foldback Protection
Foldback protection is only available on the master units as the slaves operate in
constant current mode. They should never crossover into constant voltage mode. If
foldback is triggered on the master unit, when its output shuts down, it will program the
slave unit's output to zero volts.
CONNECTING TO THE LOAD IN LOCAL SENSING MODE
(PARALLEL CONTROL METHOD)
Connect the power supplies in parallel to obtain a single output supply with a higher
output current set point. Set all of the outputs to the same voltage before connecting the
positive (+) and negative (-) terminals in parallel. The total current available is the sum
of the maximum currents of each power supply.
