Power Supply Parallel Connection - Rigol DP800A Series User Manual

Chapter 2 Front Panel Operations
2. Set proper voltage, current and overcurrent protection value for each channel
(all the channels in series connection should be working in constant voltage
mode; you should set the same current setting values and the same overcurrent
protection values for all the channels) by referring to "Constant Voltage
Output". Turn on the output of each channel.
Note: Make sure that all the channels in series connection are working in constant
voltage mode. If one of the channels is working in constant current mode, the other
channels will enter critical state in which their outputs are unpredictable.

Power Supply Parallel Connection

High currents can be provided by connecting power supplies in parallel. In this case,
the output current is the sum of the output currents of all the channels. In power
supply parallel connection, you can set the parameters of each power supply. Take
the parallel connection of two channels as an example; the connection method is as
shown in the figure below.
Operation Procedures:
1. Connect the power supply and load as shown in the figure above. Pay attention
to the polarity when making connections.
2. Set proper parameters for each channel (all the channels can work in constant
voltage or constant current mode) by referring to "Constant Voltage Output"
and "Constant Current Output". Turn on the output of each channel.
Note: All the channels can work in constant voltage or constant current mode
according to the actual need of the load.
