IT8300 series energy feedback DC electronic load can not only simulate various load characteristics, but also feed back electric energy to the power grid without pollution, which not only saves electricity consumption and heat dissipation costs, but also meets the needs of energy conservation and environmental protection. It can provide up to 10.5 kW power absorption in 3U volume, and can expand the power to 105kW or more through master-slave parallel connection and current sharing function. IT8300 series can automatically detect the power grid status, accumulate the power connected to the grid, and provide solitary bird protection function, battery test function, dynamic load mode and LIST function. Built-in LAN/USB/RS232/RS485/CAN communication interface, especially suitable for high-power power supply, storage battery, photovoltaic cell, electric vehicle, energy storage system and other testing fields.
