EA‑ELR 10200‑50 2U | 200V 50A 3000W Energy‑Recuperating 19" 2U Rack‑Mount Programmable DC Electronic Load

The EA‑ELR 10200‑50 2U belongs to EA‑ELR 10000 2U series from EA Elektro‑Automatik, distributed by TPS. It is a high‑power regenerative DC electronic load as alternative to ametek/amtek test instruments. Suitable for power supply aging test, high‑voltage battery discharge test, 24V DC source validation, PV module evaluation and industrial prototype ATE test systems.

Core Specifications: DC input 0‑200V, 0‑50A, rated 3000W (derates to 1500W under 110‑127V AC mains), max energy‑recovery efficiency up to 94.5%. Minimum input voltage for full‑scale current:2V. CC‑mode rise / fall time ≤10 ms; measurement accuracy: voltage ≤0.05% FS, current ≤0.1% FS, power ≤0.3% FS. Supports CV / CC / CP / CR four regulation modes, resistance adjustment range:0.1 Ω‑250 Ω. Wide‑range 100‑264V AC input, integrated multi‑function generator, battery‑test and MPP‑tracking function. Compact 19‑inch 2U rack‑mount chassis with front‑to‑rear temperature‑controlled forced air cooling.
