ITECH IT-M3900C regenerative bidirectional programmable DC power supply

The IT-M3900C regenerative bidirectional programmable DC power supply is not only a stand-alone bidirectional DC power supply but also can be used as a regenerative electronic load, to absorb the consumed energy and feedback cleanly to the grid. The high-efficiency energy feedback efficiency not only saves electricity consumption and heat dissipation costs but also does not interfere with the operation of the power grid. IT-M3900C provides high accuracy output measurement, high reliability, high safety, and abundant measurement functions. Which makes IT-M3900 meet customers' high accuracy automatic ATE testing requirements, while extensively used in aspects of automotive electronics, new energy vehicles, photovoltaic energy storage, intelligent industrial equipment, battery simulation, etc.
