自动转换开关主要用来检测被监测电源（两路）工作状况，当被监测的电源发生故障（如任意一相断相、欠压、失压或频率出现偏差）时，控制器发出动作指令，开关本体则带着负载从一个电源自动转换至另一个电源。当故障电源恢复正常时根据不同的工作方式（根据不同的工作需要提前设置），决定是否由现工作电原返回到原供电电源。
Automatic transfer switch is mainly used to detect by monitoring power supply (two) working condition, when the monitored power failure occurs (such as an arbitrary phase interruption, undervoltage, loss of voltage or frequency deviation), the controller sends out the action command, the switch body with loads from a power supply automatic switching to another power. When the fault of power supply returned to normal when the different work mode according to the (set in advance according to the different needs of the work), decide whether or not by the work power returns to the original power supply.
Automatic function conversion switch has to depend on the selection of the controller, the controller provides the basic functions listed below and additional function, optional features, different controller contains some or all of the following functions, the user can according to the different series of samples of products introduced selection controller satisfying products the most economical function demand of you.
1, the normal power supply voltage loss, three-phase fault phase, under voltage, over pressure automatic monitoring
2, the standby power loss of voltage, three-phase fault phase, under voltage, over pressure automatic monitoring
3, the power state, ATS working position of LED display
4, the normal power supply, standby power supply voltage of digital tube real-time indication
5, under way of working pressure range, super pressure range transfer delay, the return delay parameters, adjustable
6, automatic recovery, standby for each other, cast from the not self complex three optional operation modes
The optional 7, automatic switch, manual forced switching operation mode
8, fire linkage function can accept external passive or DC24V, AC220V fire alarm signals, to drive the ATS to make it work in double state
9, start backup generators switch, load unload
10, the mandatory equipment, the automatic conversion switch to the standby power supply position during peak demand or other design situations
11, communication, effective transmission of information and data between the computer monitoring system. The realization of the automatic transfer switch "four remote monitoring system by
In 12, operation, namely, teleindication, telemetering, remote control and remote adjustment.
Explain the dual power supply automatic switching switch mode
Automatic recovery
The normal power supply to work two power supply under normal circumstances, if the standby power supply automatic conversion to normal power supply fault (conversion delay adjustable) when the automatic return of normal power supply power returns to normal (return delay adjustable).
Mutual standby
Dual power supply for peer-to-peer priority, mutual standby power supply side, first as a working power supply, a working power supply operation process failure, automatically switch to another power supply.
Since the vote of no self complex
The normal power supply to work two power supply under normal circumstances, if the standby power supply automatic conversion to normal power supply failure, the controller stops conversion, even if the normal power supply returned to normal, the switch does not return. Press the reset key, the controller back to normal.
