Double - Source Change - Over Switch

Another aspect of dual - power switches is their categorization. There are two principal types: static transfer switches and automatic transfer switches.

Static transfer switches employ semiconductor elements to transfer power. They can attain extremely rapid transfer durations, typically on the scale of milliseconds. This is vital for certain sensitive electronic apparatuses that cannot endure even a brief power outage.

Automatic transfer switches, in contrast, are more prevalently utilized. They utilize mechanical contactors to alternate between power sources. They are relatively more economical and can manage higher power magnitudes.

Regarding installation and maintenance, when installing a dual - power switch, it is essential to guarantee accurate wiring and connection to both power sources. Routine maintenance inspections should be conducted to ensure the proper functioning of the automatic controller and the mechanical parts. For instance, examining the contact resistance of the contactors and the performance of the single - chip microcomputer within the automatic controller.
