The Rigol DP1308A is a very high quality programmable laboratory power supply with three switchable outputs (6V/5A, +25V/1A and -25V/1A) and a maximum power output of 80W. 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 DP1308A features a particularly large (10.9cm/4.3 inch) 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. 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 10.9cm (4.3 inhc) and a resolution of 480 x 272 pixels. It 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.
