1. Applicable scope and purpose<\/p>\n\n\n\n

The NDQ3H PC-grade automatic transfer switching equipment (ATSE) are applicable for sites<\/p>\n\n\n\n

with the AC voltage below 400V and the rated frequency of 50\/60Hz. This product complies with the GB14048.1-2012 and GB\/T14048.11-2016 standards in accordance with Code for Fire Protection of High-rise Civil Buildings, Code of Design on Building, Design Guidelines on<\/p>\n\n\n\n

Emergency Lighting and Code for Electrical Design of Civil Buildings, etc.<\/p>\n\n\n\n

This product mainly applies to the compulsory level I load which is widely used in important<\/p>\n\n\n\n

places that require the continuous power supply, such as fire protection, telecommunications,<\/p>\n\n\n\n

hospitals, hotels, urban rail transits, high-rise buildings, industrial assembly lines and TV stations. It adopts the network source, self-starting generator set and battery set as the main and Alternative power supplies.<\/p>\n\n\n\n
