The Rigol DP800 are programmable laboratory power supplies with 1 to 3 outputs and a maximum power output of 200 W.
Like all Rigol devices, the Rigol DP821A 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 DP821A features a relative large (8.9 cm / 3.5") and easy to read TFT monochrome 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.
