3-1-4. Series operation: For constant current output mode when using output voltage
balance function
Series operation in constant current output mode is possible by using the output voltage balance function.
Connect the VB terminals (pin No. 14 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 series.
The wires between the VB and AG terminals should be the same length and as short as possible, and
twisted or shielded wires should be used.
To protect when one unit stops, connect the HL terminals (CN41 or CN42 pin No. 7) and the DG
terminals (CN41 or CN42 pin No. 4 or pin No. 6) of all power supplies.
The wires between HL terminals and DG terminals should be the same length and as short as possible, and twisted or
shielded wires should be used.
