EA-PS 11000-30 3U Programmable DC Power Supply

The EA-PS 11000-30 3U is a high-performance programmable DC power supply from the EA Elektro-Automatik PS 10000 series, delivering up to 1000V output voltage, 30A output current, and 10000W output power in a compact 3U form factor. Designed for demanding industrial and laboratory applications, it combines autoranging technology with a wide operating range, enabling flexible testing of batteries, chargers, fuel cells, onboard chargers, and automated test systems. With a high efficiency of up to 95.5% at full load, it minimizes energy costs and heat generation, making it ideal for continuous duty. The unit features multiple operating modes (CV, CC, CP, CR), comprehensive protection functions (OVP, OCP, OPP, OT), and built-in USB, Ethernet, and galvanically isolated analog interfaces for remote control. Advanced parallel operation via master-slave and Share bus allows up to 64 units to be combined for higher power systems, ensuring scalability. The intuitive 5" color TFT touch screen with capacitive touch provides easy manual control and real-time monitoring. Key parameters include a ripple of ≤200mV rms (300kHz BW) and ≤1000mV pp (20MHz BW), an internal resistance range of 1.2Ω to 2000Ω, and output capacitance of 90μF. The DC output is isolated with DC+ to PE rated at +2000V DC and DC- to PE at ±1500V DC, ensuring safe integration into grounded systems. Additionally, remote sensing compensates for voltage drops up to 5% of nominal voltage, and the supply supports SEMI F47 voltage sag ride-through for enhanced reliability.
