EA-PS 11500-20 3U Programmable DC Power Supply – 1500V / 20A / 10000W

The EA-PS 11500-20 3U is a high-performance programmable DC power supply from the EA-PS 10000 3U series, engineered for demanding industrial, laboratory, and automated test applications. It delivers a continuously adjustable output of 0‑1500 V, 0‑20 A, and 0‑10000 W (autoranging), with efficiency up to 95.5% to minimise energy costs and heat generation. When operated on a 208 V three‑phase supply, the unit automatically derates to 6000 W, maintaining reliable performance across global grids. The power supply features a 5‑inch colour TFT touch screen with intuitive menu navigation, two rotary knobs with push‑button function, and a USB host for data logging. Built‑in galvanically isolated USB, Ethernet, and analog interfaces provide flexible remote control, while optional plug‑in modules add fieldbuses such as Profibus, Profinet, CANopen, EtherCAT, and ModBus TCP. For system expansion, master‑slave and Share‑bus parallel operation allows up to 64 units to be combined, achieving a total power of 960 kW with true summing of actual values. Regulation is precise: load regulation CV ≤0.05 % FS, CC ≤0.1 % FS, and CP ≤0.3 % FS; output ripple is ≤400 mV_rms / ≤2000 mV_pp. Comprehensive protections include adjustable OVP, OCP, OPP (0‑110 % of nominal), overtemperature, and power‑fail alarms. Remote sense compensates for voltage drops up to 5 % of U_nom, and internal resistance simulation (CR mode) extends testing capabilities. Housed in a 3U 19″ rack‑mountable chassis, this supply is ideal for battery test, fuel cell test, on‑board charger validation, industrial power systems, and laboratory research.
