EA-PS 10500-30 3U 500V / 30A / 5000W Programmable DC Power Supply

The EA-PS 10500-30 3U is a high-performance programmable DC power supply from the EA-PS 10000 3U series, designed for demanding industrial and laboratory testing applications. This robust bench power supply delivers a variable DC output of 0-500V and 0-30A, with a maximum power of 5000W (derated to 3000W when operated on a 208V AC supply). Combining autoranging technology with a wide operating range, it automatically adjusts voltage and current limits to provide maximum flexibility for applications such as battery test equipment, battery charger test, fuel cell test systems, on-board charger test, and automated test systems. Achieving up to 95.5% efficiency, this power supply significantly reduces energy costs and minimizes heat generation in your test rack.

Featuring a 5" color TFT touchscreen with gorilla glass and two rotary knobs, the EA-PS 10500-30 3U offers intuitive manual control and clear visualization of all parameters. Built-in USB and Ethernet ports, along with a galvanically isolated analog interface, enable versatile remote control and seamless integration into complex automated test systems. Optional interface modules (CAN, CANopen, RS232, Profibus, Profinet, ModBus TCP, EtherCAT) provide additional connectivity for industrial networks. Comprehensive protective functions include adjustable overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature protection to safeguard sensitive loads from overvoltage and overcurrent damage. True master-slave parallel operation and Share Bus parallel operation allow up to 64 units to be combined for higher power requirements, with automatic current sharing for system scalability up to 960 kW.

With excellent regulation specifications (load regulation CV ≤0.05% FS, line regulation CV ≤0.01% FS) and low output ripple (≤70mV rms, ≤350mV pp), the EA-PS 10500-30 3U ensures stable and clean power delivery for sensitive electronics. Remote sensing compensates for voltage drops in load leads (up to 5% of nominal voltage). Designed for reliable operation in ambient temperatures from 0°C to 50°C, it includes a temperature-controlled fan for efficient cooling. This programmable DC power supply is ideal for use as an industrial power supply, laboratory power supply, or as a core component in automated test systems requiring precise 500V output voltage, 30A output current, and 5000W output power.
