Description
Overview
The EA Elektro-Automatik EA-PSB 10500-30 3U is a three-phase rackmount bidirectional DC power supply delivering 500V/30A/5000W output power. Designed for high-performance laboratory environments, this unit operates as both a power source and an electronic load, with input compatibility for three-phase AC mains voltages from 208V to 480V. In load mode, the supply regenerates energy back to the mains grid at efficiencies exceeding 96%, reducing operational expenses and cooling requirements.
With advanced features including a 5-inch color touchscreen, integrated function generator, and comprehensive test simulation modes, the EA-PSB 10500-30 3U provides the flexibility and precision required for demanding power electronics testing, battery characterization, and renewable energy development applications.
