Overview
The EA-ELR 10500-180 4U is a regenerative programmable DC electronic load designed for comprehensive testing of DC power sources in R&D, quality assurance and production. It combines high power handling, energy recovery and flexible control interfaces for laboratory and production environments.

Key Features

• High power handling: up to 30 kW, 0–500 V and 0–180 A for testing programmable power supplies, battery systems and power converters.
• Efficient energy recovery: regenerative topology with up to 96.5% feed-back efficiency to the AC grid to reduce energy consumption and cooling needs.
• Multiple operating modes: CC (constant current), CV (constant voltage), CP (constant power), CR (constant resistance) and U/I/P autoranging for versatile test scenarios.
• Integrated function generator: DIN 40839 automotive test function plus sine, triangle, square, trapezoidal and arbitrary waveforms for dynamic testing.
• User interface: 5" color TFT capacitive touchscreen for intuitive setup, control and real-time monitoring.
• Remote programmability: RS232, USB, Ethernet (LAN), analogue control and optional digital modules (CAN, Profibus, DeviceNet, Modbus).
• Scalable system design: master-slave operation supports parallel connection of multiple units to reach system power up to 1920 kW.
• Advanced test functions: dedicated battery test modes, MPP tracking for PV simulation and data logging via USB host port.
