EA-FCTS 20920-720 is a specialized programmable fuel cell testing system with energy recovery function. The system provides power up to 180 kW, voltage range up to 920 V and current up to 720 A. Energy recovery allows returning up to 96.5% of the consumed power back to the grid, which significantly reduces operating costs. The cabinet is made in a 42U form factor with compact dimensions and high power density. The standard configuration includes built-in contactors for each channel, active pre-charge to limit inrush currents and reverse polarity protection. Voltage, current and power stabilization modes are supported with a fast response speed of up to 1 ms. Air cooling with the possibility of water cooling option. Control is available through the front panel or via digital and analog interfaces, which allows integration into automated test complexes. The EA-FCTS 20920-720 is ideal for load testing of fuel cells, energy storage systems, batteries and industrial test benches.
