One of the units operates as a master and the remaining units are
slaves. The slave units operate as controlled current sources
following the master output current. In remote operation, only the
master unit can be programmed by the computer while the slave
units may be connected to the computer for voltage, current and
status readback only.
It is recommended that each unit supplies only up to 95% of its
current rating because of the imbalance that may be caused by
cabling and connections voltage drops.
Connect the sensing circuit for either local or remote sensing as
shown in the previous figures. Set the master unit output voltage to
the desired voltage. Program the current limit to the desired load
current limit divided by the number of parallel units. During
operation, the master unit operates in constant voltage mode,
regulating the load voltage at the programmed output voltage.
