Overview

Section 3. Current Sharing

Overview

Power supplies equipped with the CANbus interface will allow current sharing between units connected in parallel. Current sharing can use a maximum of 5 supplies, including the master. All power supplies must be the same model. Every unit must have a unique address, if they do not then they will automatically readdress themselves.The slave units are shipped with the current share feature already enabled.

Figure 3.1Connections 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. The function of current sharing is to even out the current provided by each power supply.

When multiple power supplies are configured for current sharing, the master supply will make small changes to the slave’s voltage and current settings to equalize the current draw from each.

Note: Slave units will not current share with master units with firmware previous to version 5.000.
