Power Supply Series and Parallel Connections
Higher voltages can be provided when two or more insulated channels (the channels
can be from a single power supply or multiple power supplies) are connected in
series. Higher currents can be provided when two or more insulated channels (the
channels can be from a single power supply or multiple power supplies) are
connected in parallel.
Note:
1. Only insulated channels can be connected in series or in parallel.
For a single power supply, CH1 and CH2/CH3 of DP832 can be connected in
series or in parallel, but CH2 and CH3 cannot be connected in series or
parallel; any two of the three channels of DP831 can be connected in series,
CH1 and CH2/CH3 can be connected in parallel, but CH2 and CH3 cannot be
connected in parallel; the two channels of DP821 can be connected in series
or in parallel.
Channels (insulated channels) of different power supplies can be connected
in series or parallel.
2. In power series and parallel connections, the settings of the corresponding
parameters must comply with the safety requirements.
Power Supply Series Connection
Higher voltages can be provided by connecting power supplies in series. In this case,
the output voltage is the sum of the output voltages of all the channels. In power
supply series connection, you need to set the same current setting value and
overcurrent protection value for all the channels. Take the series connection of two
channels as an example; the connection method is as shown in the figure below.
