Ycq9ms Model 230/400V 125A 250A 400A 630A 800A 3p Automatic Transfer Switch ATS

  Product Catalog  Product DescriptionGeneral     YCQ9Ms series dual power automatic transfer switch is suitable for power supply system with AC 50/60Hz, rated working voltage AC400V, rated working current 800A and below. It is possible to select and switch between two power sources according to requirements, ensuring uninterrupted operation of key power sources. When one power supply has overvoltage, undervoltage or phase loss, it will automatically switch to another power supply or start the generator. Built-in RS485 communication interface, communication protocol MODBUS-RTU, realize real-time data upload, remote data configuration and status monitoring, as well as remote control, telemetry, remote control and remote adjustment functions. Mainly used in hospitals, shopping malls, banks, hotels, high-rise buildings, fire protection and other places that do not allow long-term power outages with uninterrupted power supply required.
