EA‑ELR 10750‑06 2U | 750V 6A 1500W Ultra‑High‑Voltage Energy‑Recuperating 19" 2U Rack‑Mount Programmable DC Electronic Load

The EA‑ELR 10750‑06 2U belongs to 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. Suitable for dynamic load testing, high‑voltage power‑supply validation, high‑voltage battery discharge cycling, 24V DC source verification and PV module characterization, with remote‑sense and master‑slave parallel‑expansion capability.

Core Specifications: DC input range 0‑750V, 0‑6A, rated 1500W (derates to 1200W under 110‑127V AC mains), max energy‑recovery efficiency up to 95%. Minimum input voltage for full‑scale current:2.5V. 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:4 Ω‑6000 Ω. 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.
