The MX350 controller is specifically designed for low voltage Automatic Transfer Switch (ATS) applications. The flexible control and communications options are ideal for any application. Integrated push buttons, graphical controls and LED indicators reduce external components and wiring in addition to providing local control and access to system information. Multiple communication protocols allow simple integration into monitoring and control systems.
