Power Supply Series and Parallel Connections
Higher voltages can be pro vided when t wo or more i nsulated channels (the ch annels
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:
Any two channels of DP831A can be connected in se ries; CH1 and CH2/CH3
can be connected in parallel, but CH2 and CH3 cannot be connected parallel.
CH1 and CH2/CH3 of DP832A can be connected in series or in parallel, but
CH2 and CH3 cannot be connected in series or parallel. The two channels of
DP821A can be connected in series or in parallel.
Channels (insulate d channels) of different power supplies can be connecte d
in series or in 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 t he figure above. Pay attention

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 set ting v alue s and the same overcurrent
protection values for all the channels) by refe rring 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 t he c hanne ls is working in constant current mode, the othe r
channels will enter critical state in which their outputs are unpredictable.
Power Supply Parallel Connection
High currents can be provi ded by connecting p ower 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 t he 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 refe rrin g 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 DP800A series power supply, the specified channels of
the following models support the track function.
DP831A: CH2 and CH3;
DP832A: CH1 and CH2.
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 Functi on
Press Utility System Track Set Track to select “Independent” or
“Synchronous”.
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 t ime when the track f unction 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”
For channels (the channels should be of the same instrument) that support the track
function, the tracking status of the channel voltage setting value is related to the
number of channels of which the track functions are enabled.
If only the track functi on of a single channel is en abled, the voltage set ting 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 on ly c hange 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 channe l is modified. At this point, the volta ge setting v alues of both of

Sense Working Mode
When the output current of the power supply is high, the voltage drop on the load
lead cannot be ignored. To make sure that the load can acquire accurate voltage
drop, CH2 of DP821A and DP811A (which can prov id e 10 A output cur rent) provide
the Sense (remote sense) working mode. In this mode, the voltage is sensed at the
load rather than at the power supply’s output terminals. It allows the system to
automatically compensate the voltage drop in the load leads so as to ensure the
specified output value can be consistent with the voltage received by the load.
The Sense connection method at the front panel is as shown in the figure below.
Sense Leads
Sense Leads
Operation Steps:
1. Connect the channel output terminals and Sense terminals at the front panel of
the instrument to both ends of the load, as s hown in the figure above. Pay
attention to the polarity when making connections.
2. For DP821A, after selecting CH2 (8V/10A), press Sense to enable the Sense
function.
For DP811A, after selecting the desired ra nge , press Sense to ena ble the Sens e
function.
Tip
When outputting a high current, use as short as possible and twisted load
leads in order to obt a in the best output characteristics.
Please use a twisted-pair as the Sense lead as possible as you can and the
leads should not be twisted with the load leads.
