Power Supply in Series and Parallel Connection
The DP700 series power supply supports series and parallel connections. Connecting
two or multiple power supplies in series/in parallel can provide higher
voltage/current.
In series and parallel connections, the parameter settings must comply with the
safety requirements.
Power Supply in Series Connection
The output voltage of the power supplies that are connected in series is the sum of
the output voltages of all the channels. Take the series connection of two channels as
an example. The connection method is as shown in the figure below.

Operation Procedures:
1. Connect the load and the channel output terminals as shown in the figure above.
Pay attention to the polarity when making connections (the positive and
negative polarity of each channel is connected in alternating sequence).
2. Turn on the instrument, and then refer to "Constant Voltage Output" to set
the channel output parameters that comply with the safety requirements.
(1) Set a proper output voltage for each channel.
Note: Ensure that all the channels in series connection work in the CV
mode.
(2) Set the same output current values for all the channels.
Note: The current setting values for all the channels must be the same.
(3) Set the same overcurrent protection values for all the channels and enable
the overcurrent protection function for each channel.
Note: The overcurrent protection values for all the channels must be the
same.
3. Enable the output of each channel.
