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 series; 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 sh own in the figure above. Pay attention

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 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 e nable o r disable the tr ack

functions of the two channels at the same time.

For channels (the channels should be of the same in strument) th at support th e tra ck 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, t he voltage setting val ue 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.

Equivalent Resistance

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 provide 10 A output current) 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.

 Sine

The Sine waveform is as shown in the figure below. The instrument determines the Sine amplitude according to the maximum and minimum currently set and determines the Sine pe ri od accordi ng to the total number of points (denoted by P) and the time interval currently set, thus determining the Sine w av eform. When creating par ameters, the instrument draws P values from the preset Sine waveform according to the current time interval.

 Pulse

The Pulse waveform is a s shown in the figure below. The timer parameters created from Pulse waveform only contain two gr oups of data. The f ir st group: the amplitude (voltage or current) is determined by the high level set; the time equals the pulse width (t) currently set. The second group: the amplitude (voltage or current) is deter mined by the low level set; the t ime equals the period currently set minus the pulse w idth currently set (T-t).

When Pulse is selected, if you w ant to output more than 2 groups of timer parameters, you can output the timer parameters created from the Pulse templet repeatedly by increasing the number of cycles.
