Description
Overview
The EA Elektro-Automatik EA-PSB 10750-20 is a 3U rackmount bidirectional DC power supply that functions as both power supply and electronic load. With 750V/20A output (5000W) and three-phase AC input (208-480V), it delivers efficiency up to 96%. The regenerative load mode recovers energy back to the grid, reducing operational costs and heat generation compared to traditional electronic loads.
