This product is PC-class automatic transfer switch/It is mainly used for AC 50/60HZ,rated voltage of 400V and below,and rated working current of 1250A in a two-neutral grounded power supply system.Switch between them to ensure the reliablity and safety of power supply.
The ATS has 'normally closed','backup closed'and 'two-way open' positions.It is widely used in automatic conversion of common power supply and backup power supply of power supply system or automatic conversion and safety isolation of two load devices.
The product is compliant with the standard of GB/T14048.11 'low voltage switchgear and control equipment-part 6-1:Multifunctional electrical transfer switch electrical appliances'.
Working conditions:
1.Ambient temperature:The ambient temperature is -5ºC-+40ºC,and the average temperature should not exceed +35ºC within 24 hours.
2.Atmospheric humidity:When the maxium temperature is +40ºC,the relative humidity should not exceed 50%,and the monthly maxium relative humidity is 90%.Higher relative humidity can be allowed at lower temperature.Spercial measures should be taken for the occasional condensation caused by temperature changes.
3.Installation height:The altitude of the installation site should not exceed 2000 meters.
4.Pollution level:The environmental pollution level of the installation site is level 3
5.Usage category:The use category is :AC-33B
6.Electromagnetic environment:Acclicable to environment A.The use of this product in environment B will cause harmful electromagnetic interference,in which cause the user needs to take appropriate protective measures.
