Understanding Programmable DC Power Supplies
A Programmable DC Power Supply is an essential tool in modern electronics and engineering, providing a stable and adjustable source of direct current (DC) for testing, research, and development purposes. Unlike conventional power supplies, programmable models allow users to control voltage, current, and timing digitally, offering precision and flexibility for a wide range of applications.
How Programmable DC Power Supplies Work
Programmable DC power supplies convert alternating current (AC) from the mains into a regulated DC output. What sets them apart is their ability to be programmed via interfaces such as USB, LAN, GPIB, or software platforms, allowing precise control over output parameters. Advanced models often include features like voltage and current sweeps, sequence programming, and remote monitoring, making them ideal for automated testing setups.
