RIGOL DP800 series, Three Channel DC Power Supplies

RIGOL DP800 series, Three Channel DC Power Supplies

The Rigol DP832 and DP831A are a very high quality programmable laboratory power supply with three switchable outputs (+30 V/3 A, +30 V/3 A and +5 V/3 A) and a maximum power output of 195 W.

Like all Rigol devices, the power supply features a very well constructed and easy to use interface offering comprehensive ease-of-use functions, such as programmable voltage curves. The menu has an intuitive structure.

The Rigol DP832 features a relative large (8.9 cm / 3.5") and easy to read TFT display. In addition to the normal digital displays for voltage, current, and power, these values can also be displayed as signal curves. A timer control can be used to set the output signal to different values in up to 2048 steps.

Clearly Arranged Display

All important data such as voltage, current, power, and limit values can easily be displayed on the display with a diagonal size of 8.9 cm (3.5") and a resolution of 320x240 pixels.
 
 
 

Display Signal Curves

Changes in the measurement values and settings can be presented very well and in real time using the integrated signal curve display. This makes it possible to detect things like current draw peaks, for example when the current limit is adjusted.

Programmable Timer

The voltage and current settings can be changed automatically with a timer control. Up to 100 settings can be stored for this purpose, and then activated one after another for variable intervals (specified in seconds).

Output Monitoring (option on DP832, Standard on DP832A)

The monitor can monitor the current output state of the instrument. When the user-defined monitor condition is met, the instrument executes the corresponding operation according to the setting in "Stop Mode", like showing a warning, shut off the output or produce a beep sound.

Output Analysis (option on DP832, Standard on DP832A)

The analyzer can analyze the file recorded and provides the analysis results, including the number of groups, median, mode as well as the average, VAR, range, minimum, maximum and mean deviation of the voltage, current or power of different channel.

Trigger Output (option on DP832, Standard on DP832A)

The rear panel of DP800A provides a digital I/O interface (as shown below) which supports trigger input and trigger output. The 4 data lines are mutually independent and can be used as trigger input line or trigger output line separately.

Excellent connectivity and remote control via SCPI / LabView

The Rigol DP832 can be controlled remotely with SCPI commands through a variety of interfaces. The following interfaces are available:
  • USB (standard with DP832 and DP832A)
  • LAN (optional on DP832, standard with DP832A)
  • GPIB (optional on DP832, standard with DP832A)

Control of the device can be integrated into your own applications, or by using LabView via these interfaces.
