EA-PSBE 10080-1000 4U 30 kW Programmable Bidirectional DC Power Supply

The EA-PSBE 10080-1000 4U is a high-performance, programmable bidirectional DC power supply and electronic load within the EA-PSBE 10000 series, delivering up to 30 kW of flexible power. It functions as a true two-quadrant device, operating as both a precise DC source and a regenerative sink, feeding recovered energy back into the grid with efficiency up to 95.5%. It features an autoranging output stage providing a wide operating range of 0-80 V and 0-1000 A. With a 3-phase AC input range of 208-480 V (±10%), active power factor correction (typical 0.99), and advanced digital regulation (CV, CC, CP, CR modes), it is engineered for demanding laboratory and industrial applications such as battery simulation, fuel cell testing, on-board charger evaluation, and battery recycling.

Key Features
