Operation and Features

Series connection
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.
