Product Information

The DP1308A programmable linear DC power supply is designed for performance bench and system applications. The DP 1308A provides up to 80W of total power output across three channels. It has a modern, innovative user interface simplifying front panel usability and provides all major computer I/O for system applications standard. In addition the DP 1308A has programmable output over time easily setup from the front panel and displayed on the large color screen.

It is a very high quality programmable laboratory power supply with three switchable outputs (6 V/5 A, +25 V/1 A and -25 V/1 A) and a maximum power output of 80 W. Like all Rigol devices, the laboratory power supply features a very well thought out and easy to use interface which also offers comprehensive ease-of-use functions such as programmable voltage curves. The menu follows an easy to navigate and intuitive structure.

For a laboratory power supply, the Rigol DP1308A features a particularly large (10.9 cm / 4.3") and easy to read TFT color 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 5 steps.


 Large Display
All important data such as voltage, current, power, and limit values can easily be displayed on the extra large display with a diagonal size of 10.9 cm (4.3") and a resolution of 480x272 pixels.

  Various Display Modes
The DP1308A offers a range of display modes in which the value of any output can be shown in a detail view while the two other outputs still remain visible.
  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).
  File system with USB Host
All settings can easily be stored in internal memory or on a USB stick. This allows time-consuming settings (such as timer programs) to be saved for later use.
  Integrated Online Help
As you have come to expect from Rigol, online help is also available for this laboratory power supply and provides useful information about the individual device functions.

Rigol DP1308A

I found this tri output power supply to be more useful than others i have had in the past. I like the improved user interface over other competitor's lab power supply offerings. Also, the SCPI / IVI-COM interface to PC performs as promised on NI-VISA and Keysight VISA drivers. I design/build automation test systems using this and other competitors gear and compatibility between the various OEM offerings is important. I can recommend this to any others who require programmable power supply as part of their test system.
