The controller is a mains/gens ATS controller, which can automatically or manually control the ATS dual power switch, suitable for the application of one mains and one power generation. The LCD screen can display various faults at the same time. Once the generator does not run normally, it can effectively achieve protection. It can display single-phase power generation voltage, power generation frequency, mains voltage, and mains frequency; the working mode (manual, automatic, test, shutdown) indicates the working status of the ATS switch through the LED indicator; There are Chinese/English interface options, more language can be set according to user's request. All the parameters can be configured through the front face buttons or use programmable interface by USB to adjust via PC. It has compact structure, advanced circuits, simple wiring and high reliability, It can be widely used in various types of . Main Features: Dual core 32bit high performance single chip microcomputer. LCD screen, Available in Chinese/English languages, user's language set if necessary. Collection and display, gen, mains, phase and other parameters. Automatic/Manual mode. In manual mode, can force the switch to close or open. Suitable for various AC systems (3 phase 4-wires,, single-phase 2-wire, and 2-phase 3-wire). Input/output function, status can be shown directly. Totally 3 relays output. Totally 3 configurable switch input. USB Port: parameters can be set even without power through USD port to monitor in real time. Control Protection: Realize automatic ATS switching of generator sets, perfect fault display and protection functions. Standard water-proof rubber gasket. The waterproof can reach IP65. Module design: All the connections are adapted with European connectors so that install, connection, repair and replacement can be more easily.
