EA-PS 12000-20 3U Programmable DC Power Supply – 2000V / 20A / 10kW

The EA-PS 12000-20 3U is a high-performance programmable DC power supply from the PS 10000 3U series, delivering an output voltage of 0‑2000V, output current of 0‑20A, and output power of 0‑10000W (derated to 9000W when operated on a 208V AC supply). Designed for demanding industrial and laboratory applications, it incorporates autoranging technology to provide full power across a wide voltage‑current range, making it ideal for battery charging tests, fuel cell development, on‑board charger testing, and automated test systems. With an efficiency of up to 95.5%, the unit minimizes energy costs and heat generation. The power supply features a 5" TFT touch screen with capacitive touch, two rotary knobs, and a front‑panel USB port for data logging and profile storage. Built‑in interfaces include galvanically isolated USB, Ethernet, and a 15‑pin analog interface; optional plug‑in modules (CAN, CANopen, RS232, Profibus, Profinet, EtherCAT, ModBus TCP) enable seamless integration into industrial networks. True master‑slave and Share bus parallel operation allow up to 64 units to be combined for a total system power of up to 960kW with automatic current sharing. Comprehensive protection features include adjustable OVP, OCP, OPP, and fixed OT and PF alarms. The device offers excellent technical specifications: load regulation CV ≤0.05% FS, load regulation CC ≤0.1% FS, ripple (rms) ≤400mV, ripple (pp) ≤2400mV, display accuracy voltage ≤0.05% FS, current ≤0.1% FS. Remote sensing compensates for voltage drops on DC cables. The 3U form factor is designed for 19" rack mounting with forced air cooling (front intake, rear exhaust) and operates in an ambient temperature range of 0‑50°C.
