Series connection

U8030A Series User's Guide
• Never exceed the floating voltage rating of any of the supplies.
• Never subject any of the power supplies to negative voltages.
Two or more power supplies can be connected in series or
parallel to extend the range of voltage and current. This may
serve as a lower cost alternative to a power supply with
higher power rating.
Serial connection of two or more power supplies can achieve
the output isolation rating of any one supply to obtain a
higher voltage than a single power supply. Power supplies
connected in series can be operated with one load across
both power supplies or with a separate load for each power
supply. The power supply has a diode with reverse polarity
connected across the output terminals to avoid any damages
when operated in series with other power supplies. It will be
protected if the load is short- circuited, or when one of the
power supply is turned on separately in a series- connected
power supplies.
When serial connection is used, the output voltage is the
sum of output voltage across all power supplies, while the
output current is the output current from an individual
power supply. Each power supply must be adjusted to obtain
the total output voltage.
