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 DP822/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.

Operation Procedures:

1. Connect the power supply and load as shown in the figure above. Pay attention
to the polarity when making connections.

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. Ta k e
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

Track Function

The track function is usually used to provide symmetric voltage for the operation
amplifier or other circuit. For DP800 series power supply, the specified channels of
the following models support the track function.
DP832: CH1, CH2
DP831: CH2, CH3

For channels that support the track function, you can set the tracking states of the
voltage setting value and output on/off state respectively according to your need.

To Enable the Track Function

Press Utility  System  Track Set  Track to switch between "Synchronous"
and "Independent".
 Independent: for two channels (the channels should be of the same

instrument) that support the track function, the status of the track function of
the other channel will not be affected when the track function of a channel is
enabled or disabled.

 Synchronous: for two channels (the channels should be of the same

instrument) that support the track function, the track function of the other
channel will be enabled or disabled at the same time when the track function of
a channel is enabled or disabled.

 When "Independent" is selected, users can enable or disable the track

function of a single channel freely.
When "Synchronous" is selected, users can quickly enable or disable the track



For channels (the channels should be of the same instrument) that support the track
function, the tracking status of the channel voltage setting values is related to the
number of channels of which the track functions are enabled.
 If only the track function of a single channel is enabled, the voltage setting value

of the other channel will change accordingly when the voltage setting value of
this channel is modified. At this point, the voltage setting value of the channel of
which the track function is not enabled cannot be set and can only change with
that of the channel of which the track function is enabled.

 If the track functions of the two channels are both enabled, the voltage setting

value of the other channel will change accordingly when the voltage setting
value of a channel is modified. At this point, the voltage setting values of both of
the two channels can be set.

Sense Working Mode

When the output current of the power supply is high, the voltage drop on the load
lead cannot be ignored. To ensure that the load can acquire the correct voltage drop,
CH2 of DP822/DP821 and DP813/DP811 (both provide 10A output current) provide
the Sense (remote sense) working mode. In this mode, the instrument detects the
voltage at the load terminal instead of the voltage at the output terminal of the
power supply; in this way, the instrument can automatically compensate for the
voltage drop caused by the load lead to ensure that the power supply output value
set by users is consistent with the voltage acquired by the load.
