EA-PU 10920-250 6U WC Programmable DC Power Supply Unit

The EA-PU 10920-250 6U WC is a high-performance, water-cooled, programmable DC power supply unit designed for demanding industrial and laboratory applications. As part of the EA-PU 10000 6U series, this 60 kW unit delivers a wide autoranging output of 0-920V DC and 0-250A DC, enabling flexible testing and simulation across a broad power spectrum. It features advanced digital regulation with CV, CC, CP, and CR modes, ultra-high efficiency up to 96.5%, and active Power Factor Correction (typical 0.99) for reduced grid impact. Built with a 3-phase AC input (380-480V ±10%), it supports global mains voltages. The integrated Master-Slave and Share-Bus allows seamless parallel operation of up to 64 units for systems up to 3840 kW. This water-cooled (WC) version ensures optimal thermal management in high-power, continuous operation scenarios, making it an ideal, reliable power source for applications like fuel cell simulation, electrolysis for hydrogen production, solar array testing, and electric vehicle component validation.
