YEQ3 Automatic Transfer Switch

Place of Origin: Zhejiang China
Model number: YEQ3-125/YEQ3-250
rated voltage : 400V
Certificate: IEC60947-6-1, GB/T14048.11, IEC60947-6-1.

The ambient temperature should be higher than -5℃ and lower than 40℃,and the The daily average temperature should be not exceed 35℃.
The ambient altitude should not be higher than 2000m.

With the development of society, science and technology,people require the power supply quality and reliability higher and higher,In many circumstances,people need two independent power supplies to ensure the stability;Therefore,our company developed a new series of automatic transfer switch--YEQ3 series with a high degree of automation.Its integrated design guarantees an accurate&reliable switching process,a better electromagnetic compatibility and anti-interference ability.YEQ3 series can not merely switch between two powers but can detect two lines three phase and four wire system,while any abnormal voltage was detected, the ATS will switch to the available power(Manual and Auto are both available).
YEQ3 series ATS is suitable for elevator, fire protection,subway,hospital,post station,communication station,television station,production line,shipping and any other power systems which have a high request for stability.And this automatic transfer system apply to the operating environment with AC 50/60HZ,rated voltage 400V and rated current 400A.
YEQ3 series ATS is designed according to the standard GB14048.1 IEC60947-1;GB/T 14048.11 IEC60947-6-1
Operational environment
□ The ambient temperature should be higher than -5℃ and lower than 40℃,and the The daily average temperature should be not exceed 35℃.
□ The ambient altitude should not be higher than 2000m.
□ The ambient electrical pollution class should not be higher than level 3.
□ The ambient relative air humidity should not be higher than 50%,40℃,with the decrease of temperature,the available air humidity can be properly increased,such as 20℃,90%.
□ If the environment is not up to the standard,the demand-side should notice the supply-side in advance.
