Description

Description: With the development of society, people have more and more strict requirements on the reliability of the power ***** power sources have been used in many conditions to ensure the reliability of power supply.SAQ3 series intelligent type automatic transfer switch is such a new product designed according to this requirement. Since the products have self-input and self-recover, self-input without self-recover, utility- generator, three types of applications.Detecting the three-phase four wires of utility and the three-phase voltage of two sources at the same ***** the primary power fails, such as over voltage, under voltage or loss phase, it changes over from the abnormal power to the normal power automatically. The products system in utility-generator could send out a signal, It&#**9;s perfect capability, reliability, flexibility, easy usage, wide range of dual-power products, up to the domestic level.
