EA‑PSI 10500‑20 2U | 0‑500V 0‑20A 3000W Auto‑Ranging 19" 2U Rack‑Mount Programmable DC Power Supply

The EA‑PSI 10500‑20 2U belongs to EA‑PSI 10000 2U series manufactured by German EA Elektro‑Automatik, distributed by TPS. It serves as high‑performance alternative to ametek/amtek programmable power supplies. This voltage‑current‑power auto‑ranging DC source provides nominal 3000W output power, derates to 1500W under 110‑127V AC mains. It delivers up to 95% efficiency, low‑noise output with 40 mV rms ripple and 240 μF output capacitance. Equipped with switchable 0‑5V / 0‑10V galvanically‑isolated analogue remote control. Optimized for laboratory R&D, industrial ATE test‑systems, high‑voltage high‑current battery charging, power‑semiconductor validation, fuel‑cell characterization and 24V DUT performance verification.

Core Specifications: DC output range 0‑500V, 0‑20A, rated 3000W (derates to 1500W under 110‑127V AC mains), peak efficiency up to 95%. CV ripple:40 mV rms (300 kHz BW), 500 mV pp (20 MHz BW). Regulation performance: CV load regulation ≤0.05% FS, CC load regulation ≤0.1% FS, CP load regulation ≤0.3% FS, line regulation ≤0.01% FS. Supports CV / CC / CP / CR four regulation modes, resistance adjustment range:1 Ω‑1500 Ω, output capacity 240 μF. Switchable galvanically‑isolated analog interface supporting 0‑5V or 0‑10V remote programming. Wide‑range 90‑264V single‑phase AC input with active PFC, compact 19‑inch 2U rack chassis, temperature‑controlled front‑to‑rear forced‑air cooling.
