EA-PSB 10360-240 4U Programmable Bidirectional DC Power Supply & Electronic Load

The EA-PSB 10360-240 4U is a high-performance, programmable bidirectional DC power supply that also functions as a DC electronic load, seamlessly integrating the capabilities of a laboratory power source and a programmable electronic load into a single 30 kW unit. As part of the EA-PSB 10000 4U series, this 30 kW DC power supply features energy recuperating technology, feeding up to 96% of absorbed DC energy back into the AC grid with an efficiency of up to 95.8%. It offers precise voltage regulation from 0-360V and current regulation from 0-240A, making it an ideal benchtop power supply for demanding applications. Key functionalities include a built-in function generator (sine, triangle, rectangle, ramp, arbitrary), advanced operating modes (CV, CC, CP, CR), and extensive remote control via analog, USB, Ethernet, and optional digital interfaces (CAN, Profibus, etc.). Specifically designed for complex testing scenarios, it excels as a photovoltaic panel simulator (PV simulation), battery test system for charge and discharge cycles, and a versatile power source/sink in energy recuperating systems.
