Product Description
The YCQ1F series automatic transfer switch consists of a load isolation switch (without overload and short-circuit protection mechanism) and an intelligent controller. The switch adopts an excitation type transfer mechanism, which provides faster switching speed. It also employs a new microcomputer control system for intelligent monitoring and control, strong electromagnetic compatibility, long-term continuous operation, and stability and reliability. The split-type product can be equipped with an LCD display controller, which is easy to operate, has clear indications, and provides a user-friendly human-machine interface.
The YCQ1F series automatic transfer switch is suitable for single-phase twowire/three-phase four-wire dual power supply networks with AC 230V/AC 400V rated operating voltage and rated current up to 630A. It is used to disconnect the load circuit from one power source and connect it to another power source. The transfer switch has self-action and optional manual operation features.
Standards: IEC 60947-6-1
Start generator: when fault occurs in the normal power, this port will connect after delaying some time.
Fire-fighting: Connect the fire-fighting port, doubledisconnecting light is on, the ATS double disconnect. Remove the
connection, push the automatic/manual pushbutton to reset.
Fire-fighting feedback: When ATS is in double-disconnecting state, the fire-fighting port connects.
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.
