EA‑ELR 11000‑10 2U | 1000V 10A 3000W Ultra‑High‑Voltage Energy‑Recuperating 19" 2U Rack‑Mount Programmable DC Electronic Load

The EA‑ELR 11000‑10 2U is part of EA‑ELR 10000 2U series manufactured by EA Elektro‑Automatik, distributed by TPS. It is an ultra‑high‑voltage regenerative DC electronic load as alternative to ametek/amtek test instruments. Optimized for dynamic‑profile load testing, 1000V high‑voltage power‑supply validation, high‑voltage battery discharge cycling, 24V DC source verification and PV inverter / module characterization, supporting remote‑sense and master‑slave parallel‑expansion capability.

Core Specifications: DC input range 0‑1000V, 0‑10A, rated 3000W (derates to 1500W under 110‑127V AC mains), max energy‑recovery efficiency up to 95%. Minimum input voltage for full‑scale current:4V. 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:3 Ω‑6000 Ω, output capacity 60 μF. Wide‑range 100‑264V AC input, built‑in high‑voltage discharge circuit, multi‑function generator, battery‑test and MPP‑tracking function. 19‑inch 2U rack‑mount chassis with temperature‑controlled front‑to‑rear forced air cooling.
