EA-PS 10750-20 3U Programmable DC Power Supply

The EA-PS 10750-20 3U is a high-performance programmable DC power supply from the EA Elektro Automatik PS 10000 Series, designed for demanding industrial and laboratory applications. This 3U form factor power supply delivers a wide output range of 0-750V and 0-20A, with a maximum power of 5000W (derated to 3000W when operating on 208V AC supply). Featuring advanced autoranging technology, it provides a wide operating range to adapt to various test scenarios. With up to 95.5% efficiency, it reduces energy costs and is ideal for battery test equipment, battery charger test, fuel cell test systems, on-board charger test, and automated test systems. The unit ensures protection of sensitive loads with adjustable overvoltage (OVP), overcurrent (OCP), and overpower (OPP) protections, preventing overvoltage damage. It includes built-in USB and Ethernet interfaces, plus a galvanically isolated analog interface for flexible remote control. For high-power applications, up to 64 units can be connected in master-slave parallel operation or share bus parallel operation, achieving total power up to 960kW. The intuitive 5" TFT touch screen with capacitive technology and two rotary knobs simplifies manual operation. Additional features include remote sensing, a front-panel USB host for data logging, and a slot for optional interface modules (CAN, CANopen, RS232, Profibus, etc.). Display accuracy of 0.05% for voltage and 0.1% for current ensures precise monitoring. This programmable DC power supply is the ideal choice for computer power supply testing, bench power supply needs, and as a top budget PSU for R&D and production environments.
