Product Description
DN2R series dual power automatic transfer switches are newly developed miniature
household power transfer switches . This switch is mainly used to test whether the normal or standby power supply is normal .
When the normal power supply is abnormal , the backup power supply will work immediately to ensure the continuity , reliability and safety of the power supply . This product is specially designed for home track TV installation and is specially used for Pz30 distribution box.
Series of automatic transfer switches are suitable for emergency power system 400v , 60A with AC rated current of 50v or 60Hz , compact structure , reliable conversion , easy installation and maintenance . long life . It is widely used in various occasions where continuous power failure is not allowed . It can be operated electrically or manually by ATS, and the controller.
Complies with requirements of Low-voltage Switch Gear and Control Gearspecified by IEC 60947-6-1 and IEC60947-3 : functional equipment andtransfer switch equipment
