Section 5. Current Sharing (6000 Watt only)
Overview
The current sharing function is only available for 6000 Watt units. Power supplies
can be equipped with the optional CANbus interface to allow current sharing
between units connected in parallel. Current sharing can use a maximum of 5
supplies. All power supplies must be the same model. Every unit must have a unique
address. See “Multichannel Operation (6000 Watt only)” on page 113.

Theory of
Operation
Power supplies may be connected in parallel to supply a large current to a load.
Typically, because of differences in the load connections, each power supply may
provide different amounts of current to the load.
When multiple power supplies are configured for current sharing, the master supply
will make minute changes to the slave’s voltage and current to equalize the current
draw from each.
The slaves will track the master's voltage, current, output and output on/off setting.
