EA‑ELR 10080‑120 2U | 80V 120A 3000W Energy‑Recovering 19" Rack‑Mount Programmable DC Electronic Load

The EA‑ELR 10080‑120 2U belongs to EA‑ELR 10000 2U series by EA Elektro‑Automatik, distributed by TPS. It is a regenerative DC electronic load alternative to ametek/amtek test equipment, widely deployed for battery discharge testing, power supply aging test, 24V DC source validation, fuel‑cell and PV panel characteristic evaluation in lab and industrial ATE systems.

Core Specifications: DC input 0‑80V, 0‑120A, rated 3000W (derates to 1500W under 110‑127V AC mains), max energy‑recovery efficiency up to 94%. Rise / fall time ≤10ms for CC mode; measurement accuracy: voltage ≤0.05% FS, current ≤0.1% FS, power ≤0.3% FS. Supports four regulation modes CV / CC / CP / CR, built‑in multi‑function generator, battery‑test and MPP‑tracking function. 19‑inch 2U rack design with forced front‑to‑rear air cooling.
