Suitable for AC 400V and below, rated frequency 50Hz. In case of power supply failures such as phase loss, overvoltage, or undervoltage, the transfer switch under the control of the controller can quickly switch the load from the main power supply to the backup power supply (the backup power supply must be normal at this time). Users can also place the load in an intermediate position when needed, so that the load is neither connected to the main power supply nor the backup power supply.

Normal close: When the normal power of ATS is in closing state closing signal without power is output from this port.
Standby close: When the standby power of ATS is in closing state,closing signal without power is output from this port.
Normal earth wire: When ATS are 3 phases, the normal earth wire is connected into this port.
Standby earth wire: When ATS are 3 phases, the standby earth wire is connected into this port.
Remark: The normal earth wire and standby earth wire is just suitable for ATS of 3 phases.
