EA‑ELR 10500‑10 2U | 500V 10A 1500W Energy‑Recuperating 19" 2U Rack‑Mount Programmable DC Electronic Load

The EA‑ELR 10500‑10 2U belongs to EA‑ELR 10000 2U series from EA Elektro‑Automatik, distributed by TPS. As high‑voltage regenerative DC electronic load alternative to ametek/amtek test instruments, it is ideal for dynamic load testing, high‑voltage power‑supply validation, battery discharge cycling, 24V DC source verification, PV module characterization and industrial ATE systems, supporting remote‑sense and master‑slave parallel expansion.

Core Specifications: DC input range 0‑500V, 0‑10A, rated 1500W (derates to 1200W under 110‑127V AC mains), maximum 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:2 Ω‑3000 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.
