EA-PSI 10200-140 3U 10kW Programmable DC Power Supply

The EA-PSI 10200-140 3U is a high-performance programmable DC power supply from the EA-PSI 10000 3U series, delivering up to 200V output voltage, 140A output current, and 10kW output power in a compact 3U 19-inch rack-mount form factor. It features an ultra-low ripple of ≤40mV rms (BW 300kHz) and ≤300mV pp (BW 20MHz), with an efficiency of up to 94.5% at full load, ensuring reliable and clean power for demanding applications such as battery testing, battery charger testing, and industrial automation. The integrated function generator supports sine, triangle, rectangular, trapezoidal, arbitrary waveforms, and specialized profiles like DIN 40839 engine start simulation, EN 50530 PV inverter testing, and fuel cell simulation, eliminating the need for external equipment and reducing test setup time. With remote sensing to compensate for voltage drops, true master-slave parallel operation for up to 64 units (totaling 960kW), and extensive digital interfaces (USB, Ethernet, galvanically isolated analog) plus optional fieldbus modules (CAN, Profibus, EtherCAT), the EA-PSI 10200-140 3U offers unparalleled flexibility and scalability. The intuitive color TFT touchscreen, adjustable protection settings (OVP, OCP, OPP), user profiles, and adjustment limits make it easy to configure and operate, while its robust design and compliance with safety standards ensure long-term reliability in industrial environments.
