This series of Automatic transfer switch is suitable for AC 50Hz/60Hz, rated working voltage 230V/400V and below power distribution and control circuit.The current up to 63A. It is mainly used as the main switch of terminal electrical appliances, and can also be used to control various types of motors, low-power electrical appliances,lighting and other places.

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.

1. Can work in the environment of -5°C~40°C

2. The altitude of the installation site does not exceed 2000m

3. When the highest temperature is +40°C, the relative humidity of the air should not

exceed 50%

4. Higher humidity is allowed at lower temperature, 20°C~90%

Standard: IEC 60947-6-1

YCQ9HB ATS appliances are suitable for AC 50Hz, rated working voltage 400V and below,rated current 10A to 63A dual power supply system, the power supply system of the two power sources: common power supply (N) and standby power supply (R) at the same time detection, when the power supply occurs undervoltage, phase failure power supply failure that is, automatic switching from the abnormal power supply to the normal power supply (can also be manually switched), to enhance the continuity and reliability of the power supply system in the use of the premises. This improves the continuity, safety and reliability of the power supply system at the place of use. 

Switching appliances are widely used in power systems, hospitals, postal and telecommuni cation, fire fighting, hotels, banks, airports, wharves, residential neighborhoods, TV stations, military facilities, shopping malls and other important places where the continuity of power supply is required.
