EA-PSI 10080-340 3U 10000W Programmable DC Power Supply

The EA-PSI 10080-340 3U is a high-performance programmable DC power supply from the EA Elektro-Automatik PSI 10000 Series, delivering up to 80V output voltage and 340A output current with a total power of 10000W in a compact 3U form factor. This versatile unit excels as a bench power supply, battery test equipment, and battery charger test solution, featuring ultra-low ripple of ≤10mV RMS and ≤100mV P-P, ensuring clean and stable power for sensitive applications. With an adjustable resistance range of 0.008Ω to 13Ω and a high output capacitance of 15980µF, it accurately simulates real-world conditions and handles dynamic loads with ease. The integrated function generator supports complex test sequences including sine, triangle, rectangle, trapezoid, DIN 40839, and arbitrary waveforms, while the extended PV function complies with EN 50530 for solar inverter testing. Remote control is versatile via built-in USB, Ethernet, and galvanically isolated analog interface, with optional modules for CAN, CANopen, RS232, Profibus, Profinet, ModBus TCP, and EtherCAT. The master-slave parallel operation allows up to 64 units for scalable power systems, and the high efficiency of up to 94.5% minimizes energy loss. Ideal for automated test systems, R&D labs, and industrial applications, the EA-PSI 10080-340 3U combines precision, flexibility, and reliability.
