EA-EL 9750-10 DT 600W Programmable DC Electronic Load

The EA-EL 9750-10 DT is a compact, high-performance benchtop electronic DC load from the EA-EL 9000 DT series, designed for versatile testing applications in laboratories, schools, and workshops. It features a wide input range of 0-750V and 0-10A, with a maximum power handling of 600W at 25°C. This unit supports all four essential regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR). Operation is intuitive via a multilingual color TFT touch panel, complemented by two rotary knobs and a pushbutton. Its built-in true function generator can create and apply standard waveforms (sine, rectangle, triangle) or complex arbitrary sequences to the input, perfect for dynamic testing. Specialized functions include a dedicated battery test mode for measuring capacity (Ah) and energy (Wh), and an MPP (Maximum Power Point) tracking function for photovoltaic panel and inverter testing. For connectivity and automation, it comes standard with galvanically isolated USB, Ethernet, and analog interfaces, and is fully controllable via SCPI commands, ModBus RTU, or the included EA Power Control software for Windows.
