Introduction
The ATL900 control unit implements state-of-the-art functions required for automatic transfer applications.
The system incorporates a unique series of hardware and software features which guarantee high flexibility, e.g. management of three supply source lines and two tie breakers,
graphic display, double power supply, expansion modules, programmable system layout, integrated PLC etc., for use in a wide variety of possible conditions of application, all of
which can be programmed by the user. The graphic display shows and allows to control the system situation effectively. The expansion slots allows to increase the hardware
resources also allowing adaptability to future needs.
