Automatic transfer switch electrical appliances comply with GB/T14048.11 standard,as well as the "Fire Protection Code for High rise Civil Buildings","Guidelines for Emergency Lighting Design",etc.The components and parts of the product undergo strict aging screening, and the finished product can only be shipped after passing the confirmation inspection.This ensures the reliability and safety of the product.

Suitable for distribution systems with a rated operating voltage of AC400v. When there are faults such as phase loss,overvoltage,undervoltage,etc.in the power supply,the transfer switch under the control of the controller can quickly switch the load from the common power supply to the backup power supply (at this time,the backup power supply must be normal).Users can also place the load in an intermediate position when needed,so that the load is neither connected to the regular power supply nor to the backup power supply. This product is mainly used for the first and second level loads specified by the state,and is widely applicable to places that require continuous power supply,such as fire protection postal and telecommunications,hospitals,hotels,urban rail transit,high-rise buildings,industrial assembly lines,television stations,etc.The backup power source can be the power grid,self starting generator sets,battery packs,etc.
