3.6 Serial
Operation
Serial connection is used to connect two or more power supplies in series to obtain a higher voltage ratings
(maximum 240V for this power supply).
Figure 7 shows the serial connection between two 6303D power supplies at series tracking. One unit is set at
60V/2A (MASTER setting is 30V/2A) while the other is at 40V/3A (MASTER setting is 20V/3A). Figure 8
shows the serial connection voltage/current output versus load changes.
