The Rigol DP831A is a very high quality programmable laboratory power supply with three switchable outputs (+8 V/5 A, +30 V/2 A and -30 V/2 A) and a maximum power output of 160 W.
Like all Rigol devices, the power supply features a very well constructed and easy to use interface, which also offers comprehensive ease-of-use functions, such as programmable voltage curves. The menu has an intuitive structure.
The Rigol DP831A features a relative large (8.9 cm / 3.5″) 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 2048 steps.
