YCQ9Ms Automatic transfer switch
General
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 automaticallyswitch 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°C2. The altitude of the installation site does not exceed 2000m3. When the highest temperature is +40°C, the relative humidity of the air should notexceed 50%4. Higher humidity is allowed at lower temperature, 20°C~90%Standard: IEC 60947-6-1 -
YCQD7 Series integrated star delta starter
The YCQD7 series intelligent integrated star-delta starter (hereinafter referred to as the starter) is suitable for three-phase squirrel-cage asynchronous motors with an AC frequency of 50Hz, a rated voltage of 380V/400V, a rated operating current of up to 110A (phase current when the starter is in delta connection), and a control power of up to 90kW. It is used to control the starting, running, and stopping of three-phase squirrel-cage asynchronous motors with a stator winding connection changed from star to delta, thereby reducing the starting current and the impact of motor starting on the transmission network.
The starter adopts modular design and integrated structure, integrating contactor, intelligent controller and auxiliary contactor. The intelligent controller can automatically control the starter operation according to the predetermined program to complete the star-delta starting of the motor.
