EA Elektro-Automatik EA-PSB 10360-40 3U Bidirectional DC Power Supply

Overview

The EA Elektro-Automatik EA-PSB 10360-40 3U is a programmable bidirectional DC power supply featuring three-phase AC input (208–480V) for industrial and laboratory applications. As both a power source and electronic load, it regenerates energy back to the AC mains with efficiency up to 96%, reducing operational costs and thermal load. The 3U rackmount design delivers up to 5000W of DC output at 360V, 40A.

This high-performance unit features a 5-inch touch-control TFT display, 16-bit digital regulation with selectable control speeds, and flexible autoranging output stages. Advanced capabilities include integrated function generation, battery and fuel cell simulation, and photovoltaic system emulation. Multiple units can be paralleled using the Master-Slave bus to build systems up to 15 kW per unit and beyond.
