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 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
YCQ1F series excitation type Automatic Transfer Switch (ATS)

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.
YCQR-63 Mini automatic transfer switch（PC class)

YCQR-63 automatic transfer switch is a PC class infrequent change-over switch, with two-station design (commonly used for A and standby for B), suitable for AC systems with AC 50-60hz and rated current 6A-63A.

The main function of the automatic transfer switch is when the main power (common power supply A) fails, the ATS will automatically switch to the backup power (Backup power supply B) to continue working (switching speed <50 milliseconds), which can effectively solve the troubles caused by power outages.
YCQ4E/YCQ4R PC type Automatic Transfer Switch

The dual power automatic switch is a newly developed miniature household power switch,which is mainly used to test whether the main power supply or

standby power supply is normal.When the normal power supply is abnormal, the standby power supply starts to work immediately,which ensures the

continuity,rel iabi l ity and safety of power supply,This product is special ly designed for household rail installation and is specially used for Pz30 distribution box.
YCQ9E Automatic transfer switch

General
YCQ9E series automatic transfer switch, rated working curent 16A to 630A,to be used in pow- er systems for ensuring the continuity of the supply, by transfering a load between two power supply sources. The switch has three working posions of “Main ( I ) cosing”, “Standby ( II )
closing” and “Double-of (0)”, which can be used for fire-fighting linkage and infrequent con-
necion and disconnecion of power supply systems. Mainly used in hospitals, shopping malls, banks, chemical industy, metalurgy, high-rise buildings, military facilities and fire-fighting occa- sions where power failure is not allowed.
