The Rigol DP821 is a very high quality programmable laboratory power supply with two switchable outputs (60 V\/1 A and 8 V\/10 A) and a maximum power output of 140 W.<\/p>\n

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.<\/p>\n

The Rigol DP821 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.<\/p>\n
