EA‑PSB 10200‑50 2U | 200V 50A 3000W Auto‑Ranging Bidirectional Regenerative 19" 2U Rack‑Mount Programmable DC Power Supply

The EA‑PSB 10200‑50 2U belongs to EA‑PSB 10000 2U bidirectional series manufactured by German EA Elektro‑Automatik, distributed by TPS. It is a high‑performance alternative to ametek/amtek programmable power supplies. This two‑quadrant autoranging unit integrates precision DC source and regenerative electronic sink load with seamless automatic source‑sink transition. Ideal for laboratory R&D, industrial ATE test‑systems, high‑voltage battery charge‑discharge cycling, fuel‑cell characterization, 24V DUT validation and power‑component test applications.

Core Specifications: DC output range 0‑200V, 0‑50A, rated ±3000W (derates to ±1500W under 110‑127V AC mains), max sink/source efficiency up to 94.5%. CV ripple:30 mV rms (300 kHz BW), 300 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:0.1 Ω‑250 Ω, output capacity 1600 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.
