EA Elektro-Automatik EA-ELR 11500-06 2U Regenerative DC Load

Overview

The EA-ELR 11500-06 2U is a programmable regenerative electronic DC load in a 2U rackmount form factor. It accepts single-phase AC input (110-240V) and handles DC loads up to 1500V and 6A with a maximum power rating of 3kW. The unit features active power-factor-correction and regenerative operation that recovers energy and returns it to the grid with greater than 95% efficiency.

Key Features

• True autoranging design allows maximum power sinking across variable voltage and current combinations
• Regenerative operation with >95% efficiency energy recovery to the grid
• Active power-factor-correction with typical 0.99 PFC
• Regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), Constant Resistance (CR) with fast crossover
• 16-bit ADCs and DACs with selectable control speed (Normal, Fast, Slow)
• Color 5" TFT touchscreen display with intuitive user interface
• Integrated function generator with predefined waveforms for dynamic testing
• Galvanically isolated Share-Bus for parallel operation with other ELR 10000 series models
• Master-Slave configuration supports up to 64 units in parallel
• Control via SCPI, ModBus, LabVIEW, and IVI drivers

Applications

• Battery and cell testing with dedicated battery test mode
• Photovoltaic system evaluation with MPPT (Maximum Power Point Tracking) functionality
• Power supply testing and verification
• Arbitrary waveform generation for dynamic source testing
• Parallel rack configurations for moderate-power system testing
