Is ATS directly proportional to switching time?
The common user should stress “Total reacting time” or “Switching time” to meet demands of different electricity distribution system. ATS is not directly proportional to switching time. To the inductive load, when ATS switch to the backup from common power supply, the load produces counter potential, which may produce large impact current together with potential of backup power supply. And the load equipment will get great mechanical stress and it will cause fuse burnt out or breaker tripping. Therefore the civil rules regulates “when the electrical load permits intermit time within 1.5s, UPS should be set”. So ATSE is not UPS and can not replace UPS, therefore, the switching time is not more shorter more better. Which fire fighting signals does function accept? In order to meet demands of different fire fighting centers and practical spot design, the integrated fire function of our product accepts DC24V or AC220V constant voltage type or pulse mode fire alarm signals. Constant-voltage
