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.
