EA-PSI 11000-30 3U 10000W Programmable DC Power Supply

The EA-PSI 11000-30 3U is a high-performance programmable DC power supply from the EA Elektro Automatik PSI 10000 Series, engineered to deliver up to 1000V output voltage, 30A output current, and 10000W output power in a space-saving 3U form factor. Designed for demanding applications such as battery test equipment, battery charger test, computer power supply testing, and automated test systems, this bench power supply combines precision, versatility, and industrial-grade reliability. Featuring an integrated XY table generator and sequence programming, it can simulate real-world conditions and generate complex test sequences, eliminating additional equipment and reducing test setup time. The unit includes an advanced function generator capable of sine, triangle, rectangle, trapezoid, arbitrary waveforms, and specialized profiles like DIN 40839 for automobile engine start simulation, simple PV (photovoltaics), FC (fuel cell), and extended PV simulation per EN 50530 compliance. The built-in variable internal resistance allows accurate simulation of batteries and fuel cells, while the low ripple of ≤200 mV RMS (BW 300 kHz) and ≤1000 mV P-P (BW 20 MHz) ensures clean, stable output for sensitive loads. Efficiency reaches up to 95.5%, and the device includes comprehensive protections: OVP, OCP, OPP, overtemperature, and power fail. Remote control is supported via built-in USB, Ethernet, and a galvanically isolated analog interface, with optional modules for Profibus, Profinet, CANopen, ModBus TCP, and more. The intuitive 5" TFT touch screen and dual rotary knobs provide easy manual operation, and up to 64 units can be paralleled in master-slave mode for higher power systems with true summing of actual values, offering total system power up to 960 kW.
