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.
