Overview

PASCO's DC Programmable Power Supply functions as a simple constant-voltage source and is able to output periodic functions and has added features with custom programs. The Programmable Power Supply works well with a variety of electronic circuits, motors, lamps, heaters, Peltier devices and with a variety of PASCO apparatus.

The Power Supply indicates its output voltage, output current, and settings on the digital display. The type of data shown on the display is indicated by the Voltage, Current, and Time LEDs. 

Functions include Rectangle Wave, Stair, Ramp and custom programmable and playable adjustments. Constant DC mode allows display between voltage and current with cycle times you can adjust and customize.
