Switch Cabinet,Automatic transfer switch panel, and free from outside influence and power grids have misoperation
2, the DC coil excitation pulse, the energy savings, lower noise and reduce coil aging guarantee
3, switching and fast (less than 80ms), a specific time delay settings (0-30S)
4, achievable manual / automatic conversion
5, YEQ2 type automatic switch as the electrical switches at the core, can be widely applied and the power, telecommunications, oil, coal, municipal, fire protection, railways, intelligent buildings and television stations require continuous supply of important sites
6, dual automatic switching power supply intelligent controller for the microprocessor core to be accurate way to accurately detect two three-phase voltage, the voltage anomalies (lost electricity, overvoltage, undervoltage, lack of) make accurate judgment, the delay can be controlled switching ATS
7, controllers delay a way power issued after launching function signal generator group

 

 

Transfer switches are used to protect critical electrical loads against loss of power. The loads normal power source is backed up by a secondary (emergency) power source. A transfer switch is connected to both the normal and emergency power sources and supplies the load with power from one of these two sources. In the event that power is lost from the normal power source, the transfer switch transfers the load to the secondary (emergency) power source. Transfer can be automatic or manual, depending upon the type of transfer switch equipment being used. Once normal power is restored, the load is automatically or manually transferred back to the normal power source, again depending upon the type of transfer equipment being used.

In automatic transfer switch equipment, the switchs intelligence system initiates the transfer .when normal power fails below a preset voltage. If the emergency power source is a standby generator, the transfer switch initiates generator starting and transfers to the emergency power source when sufficient generator voltage is available. When normal power is restored, the transfer switch automatically transfers back and initiates engine shutdown. In the event the normal power source fails and the emergency power source does not appear, the automatic transfer switch remains connected to the normal power source until the emergency power source does appear. Conversely, if connected to the emergency power source and the emergency power source fails while the normal power source is still unavailable, the automatic transfer switch remains connected to the emergency power source.
