IT-M3900B-series

Regenerative Power System

IT-M3900B regenerative power system feature two-in-one, which could use as a bidirectional DC power supply, also act as an independent regenerative load. One-button-switch between source and load mode, a unique and decisive feature for the user groups that works in different applications such as battery, PV energy storage, electric vehicle, Green energy and some ATE fields.
