1.Applicable Scope and Purpose<\/p>\n\n\n\n

The NDQ3-250 P-grade ATSE are applicable for sites with the AC voltage below AC380V.AC400V.AC415V and the rated frequency of 50Hz. 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 Emergency Lighting, 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 places that require the continuous power supply, such as fire protection, telecommunications, 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 standby power supplies.<\/p>\n\n\n\n

Note 1: blank type means the integral or split type (only two segments).<\/p>\n\n\n\n

Note 2: N-type represents three-segment type (for both integral and split types), and communication type needs the special contract review (only the integral type)<\/p>\n\n\n\n

Note 3: D-type is limited to the split type (for both two segments and three segments), it is default with automatic change and automatic recovery in the factory setting, and the customer may set the control mode<\/p>\n\n\n\n
