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.

Figure 5.1Connections for Current Share Operation

Theory of Power supplies may be connected in parallel to supply a large current to a load. Operation 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.
