EA-PS 10500-90 3U 15kW Programmable DC Power Supply – 500V / 90A

The EA-PS 10500-90 3U is a high-performance programmable DC power supply from the EA Elektro Automatik PS 10000 Series, delivering 0-500V output voltage, 0-90A output current, and up to 15000W output power in a compact 3U form factor. Featuring advanced autoranging technology, this industrial and laboratory power supply maintains full power over a wide operating range, making it ideal for battery test equipment, battery charger test, fuel cell test systems, on-board charger test, and automated test systems. With an impressive efficiency of up to 95.5%, it reduces energy costs and minimizes heat generation, ensuring reliable operation in demanding environments. The unit offers low ripple (≤70mV rms, ≤350mV pp), adjustable internal resistance (0.2-330Ω) for realistic load simulation, and comprehensive protections (OVP, OCP, OPP, OT) to protect sensitive loads from overvoltage and overcurrent damage. It supports master-slave parallel operation and share bus parallel operation for scalable power systems up to 960kW with 64 units. Built-in USB, Ethernet, and galvanically isolated analog interfaces enable seamless integration into automated test systems, while optional fieldbus modules (CANopen, Profibus, Profinet, ModBus TCP, EtherCAT) provide flexibility for industrial communication. The EA-PS 10500-90 3U is the ideal programmable DC power supply for testing power supplies, batteries, chargers, and fuel cells, ensuring precise and efficient power delivery.
