3-1-3. Parallel operation: For constant voltage output mode when using output
current balance function
Parallel operation in constant voltage output mode is possible by using the output current balance function.
Connect between the CB terminals (pin No. 13 of CN41 or CN42) and the AG terminals (pin No. 11 or pin
No. 12 of CN41 or CN42) of all power supplies operating in parallel.
The wires between CB terminals and AG terminals should be the same length and as short as possible, and
twisted or shielded wires should be used.
Make sure that the load wires from each power supply are the same size and length.
