Single DC Power Supplies

Single-output DC power supplies provide one isolated, regulated output and are the standard bench instrument for powering a device under test.

Keysight, EA Elektro-Automatik, Preen and Chroma cover this range. Voltage and current ratings are the starting point, but three further specifications usually decide the choice. Programming and readback resolution separate a laboratory instrument from a general-purpose bench supply and determine whether it can be used inside an automated test sequence. Load regulation and transient response matter if your device draws current in bursts. Protection behaviour, meaning overvoltage, overcurrent and reverse-polarity handling, decides what happens to your hardware when something goes wrong. Tell us the load profile.
