EA-EL 9750-05 DT 400W Programmable Electronic DC Load

The EA-EL 9750-05 DT is a 400W benchtop DC electronic load from the EA-EL 9000 DT series, designed for precise testing of power supplies, batteries, and solar inverters. It supports four regulation modes: constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR). With a wide input voltage range of 0–750V and a maximum current of 5A, it is ideal for high-voltage, low-current applications in labs, schools, and workshops.

Equipped with an intuitive multilingual color touch panel, a built-in true function generator, and multiple remote control interfaces, it offers both ease of use and advanced programmability. The device also features comprehensive protection functions including OVP, OCP, OPP, and thermal derating to ensure safe operation.
