The IT-M3900B Feedback Source Load System incorporates two devices in one machine, which can be used as a bi-directional power supply to provide power, or as a stand-alone feedback load. A single button allows the IT-M3900B to switch freely between the two models, making it a multi-purpose machine that not only saves the user cost, but also saves time and space. Widely used in battery, energy storage, new energy vehicles, green energy, ATE construction and other testing fields.
Bi-directional power supply and feed-back load, one machine for two purposes.
One button switching between source and load at the panel
