EA Elektro-Automatik EA-ELR 10500-90 3U US208V Regenerative DC Load

Overview

The EA Elektro-Automatik EA-ELR 10500-90 3U is a programmable regenerative electronic DC load rated at 15kW. This 3U rackmount unit accepts 3-phase AC input (208V–480V) and can sink DC loads up to 500V at 90A. The regenerative design recovers power from the load and feeds it back into the AC supply with greater than 96% efficiency, reducing operating costs and environmental impact.

Key Features

• 15kW power rating with 500V/90A DC capacity
• Regenerative operation recovers energy to the grid with >96% efficiency
• Autoranging functionality for maximum power across varying voltage and current combinations
• 5-inch color TFT touchscreen with intuitive user interface
• Multiple regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), Constant Resistance (CR)
• Integrated arbitrary waveform function generator for dynamic testing
• Battery test and photovoltaic MPPT test modes
• Galvanically isolated Share-Bus and Master-Slave capability for parallel operation (up to 64 units)
• Command interfaces: SCPI, ModBus, LabVIEW, and IVI drivers

Applications

• Power supply and battery charger testing and validation
