EA Elektro-Automatik EA-ELR 10200-50 2U Regenerative DC Load

Overview

The EA Elektro-Automatik EA-ELR 10200-50 2U is a programmable regenerative electronic DC load designed for testing and simulating power sources. This 2U rackmount unit features a maximum input of 200Vdc and 50A capacity with 3kW power rating. The regenerative capability recovers energy and feeds it back to the AC grid with over 96% efficiency, reducing operational costs and heat generation.

Key Features

• Regenerative technology with energy recovery to grid at >96% efficiency
• Autoranging allows maximum power sinking across wider voltage and current ranges
• Color 5" TFT touchscreen with intuitive user interface
• Multiple regulation modes: CV (Constant Voltage), CC (Constant Current), CP (Constant Power), CR (Constant Resistance)
• Digital regulation with 16-bit ADC/DAC and selectable control speed (Normal, Fast, Slow)
• Integrated function generator with predefined waveform curves
• Battery test mode for characterizing battery performance
• Photovoltaic (MPPT) test mode for solar source simulation
• Master-Slave bus configuration supports parallel operation of up to 64 units
• SCPI and ModBus control languages with LabVIEW and IVI driver support
• Active Power-Factor-Correction (PFC) with typical 0.99 power factor

Applications

• Power supply design and testing
• Battery characterization and validation
• Renewable energy source simulation (photovoltaic, wind)
• Electric vehicle and energy storage system testing
• Dynamic load simulation for power electronics development
