EA‑PSB 10750‑12 2U | 750V 12A 3000W Auto‑Ranging Bidirectional Regenerative 19" 2U Rack‑Mount Programmable DC Power Supply

The EA‑PSB 10750‑12 2U belongs to EA‑PSB 10000 2U bidirectional series manufactured by German EA Elektro‑Automatik, distributed by TPS. It is high‑performance alternative to ametek/amtek programmable power supplies. This two‑quadrant auto‑ranging regenerative unit functions as both programmable DC source and electronic DC load with energy recuperating capability. Built‑in solar‑panel simulator, PV‑inverter and fuel‑cell simulation functions, with seamless source‑sink transition. Ideal for laboratory R&D, industrial ATE test‑systems, photovoltaic inverter testing, fuel‑cell characterization, high‑voltage battery cycling and 24V DUT validation.

Core Specifications: DC output range 0‑750V, 0‑12A, rated ±3000W (derates to ±1500W under 110‑127V AC mains), sink‑source recuperation efficiency up to 95%. CV ripple:50 mV rms (300 kHz BW), 500 mV pp (20 MHz BW). Measurement accuracy: voltage ≤0.05% FS, current ≤0.1% FS, power ≤0.3% FS. CC‑mode rise / fall time ≤10 ms. Supports CV / CC / CP / CR four regulation modes, resistance adjustment range:2 Ω‑3000 Ω, output capacity 80 μF. Galvanically‑isolated analog interface with selectable 0‑5V / 0‑10V remote programming. Universal 90‑264V single‑phase AC input with active PFC, compact 19‑inch 2U rack chassis, temperature‑controlled front‑to‑rear forced‑air cooling.
