DVB01 module is a multi-function voltage monitoring controller, using industrial-grade micro-controller as the main control unit, measuring a wide range of high precision. The controller prefers 5 different functions, and can customize and add other specific functions according to user's requirements. The module is made of genuine high-quality components carefully processed, stable performance, can be widely used in a variety of voltage measurement and control applications.
