Digimess PN300

The Digimess PN300 is a serviced and calibrated three-channel programmable laboratory power supply for electronics workshops, service benches and automated test setups. It provides two adjustable 30 V / 2.3 A outputs plus an always-active 5 V auxiliary output.

This is a fully linear low-noise bench supply, suitable for applications where clean output behavior matters more than compact switch-mode efficiency. Typical uses include audio circuit development, analogue electronics work, battery characterization and controlled charging setups using computer-based control and data logging.
