EA-PU 12000-80 6U WC 60kW Programmable DC Power Supply with Water Cooling

The EA-PU 12000-80 6U WC is a high-performance, water-cooled, programmable DC power supply unit from EA Elektro-Automatik, delivering a robust 60kW of constant power. Designed for demanding industrial and laboratory applications, it features an exceptionally wide output range of 0-2000V and 0-80A, providing maximum flexibility within its power envelope. The unit boasts a wide three-phase AC input range (380-480V ±10%) with active Power Factor Correction (PFC) achieving ~0.99, ensuring high efficiency up to 96.5% and minimal grid impact. With 16-bit ADC/DAC resolution, it offers precise digital control in CV, CC, CP, and CR modes with fast crossover. Built for system scalability, it includes a galvanically isolated Master-Slave Bus and Share-Bus for seamless parallel operation of up to 64 units, enabling systems up to 3840kW. Standard interfaces include USB and Ethernet for control, with options for CAN, Profinet, EtherCAT, and more. The integrated water cooling (WC) option ensures reliable thermal management in high-power, continuous operation scenarios such as electrolysis, fuel cell simulation, and testing of high-voltage components like solar inverters and electric vehicle systems.
