Overview

The EA-ELR 10200-25 2U is a programmable electronic DC load from the EA-ELR 10000 2U series designed for laboratory and industrial test applications. It offers energy-recovery capability, a compact 2U 19-inch rack form factor and a wide set of control and protection functions for precise, repeatable DC testing.

Key features

• Programmable DC electronic load with energy recovery up to 94.5%.
• Rated output up to 1500 W (derates to 1200 W at 110-127 V AC); output voltage 0-200 V; output current 0-25 A.
• Multiple operating modes: CV, CC, CP, CR and additional resistance mode and built-in function generator.
• Intuitive local interface: 5-inch color TFT touchscreen and rotary knobs with decimal switching; DC on/off control and clear status display.
• Extensive remote and analog interfaces: galvanically isolated USB, Ethernet (SCPI / ModBus RTU), 15-pin D-Sub analog I/O (0-5 V / 0-10 V); compatible with LabView VIs and EA Power Control software.
• Scalable operation: parallel operation support (up to 64 units) and remote sensing for higher power or distributed testing.
• Comprehensive protections and front-to-rear, temperature-controlled cooling for reliable operation in lab and industrial environments.
