The Advantages of Installing an Automatic Changeover Switch
Reliability of Power
A power outage means that all ongoing work is halted. Consider the task of database maintenance for an airline; if the power goes out unexpectedly, the entire administration fails to coordinate worldwide balance. In such cases, a generator is employed as a backup, but without an automatic Changeover switch, the advantage becomes a human liability as well as a waste of crucial time. With these controls, you can limit the function of your generator and use uninterrupted electricity.
Simple Operations
Following the installation of a changeover switch, particular procedures are established to automatically power various equipment, machines, and gadgets. Connect your lights, freezers, industrial equipment, and other devices to provide an uninterrupted power supply. This technique not only restores power after a power outage or blackout, but it also improves the mechanical functionality of the generator, increasing its durability.
Protecting Sensitive Equipment
For companies that rely on sensitive electronic equipment, power outages can cause irrevocable harm. An Automatic Changeover Switch protects your precious equipment from potential injury and extends its longevity by preventing sudden power surges or drops.
Power Availability
Power outages can happen anytime and have serious effects, especially for important activities. You can ensure continuous power availability using an Automatic Changeover Switch. Your switch will respond promptly, day or night, to provide a continuous power supply, keeping your activities running smoothly.
Safety
Power is indeed related to bodily danger. People in this line of work are at risk of bodily damage during an outage or blackout, especially if it is handled manually. Handling a generator that requires manual hook-ups can be hazardous. Automatic changeover switch, on the other hand, eliminates such risks. They not only make every changeover automatic, but they also eliminate any risks involved with dealing with generators in the dark.
Automatic Transfer Switch Vs Static Transfer Switch
|
Automatic Transfer Switch |
Static Transfer Switch |
|
An automatic transfer switch is an intelligent & self-acting power switching device. |
A static transfer switch is intelligent and automatic and fixed switching equipment. |
|
The main function of an ATS is to transfer the power supply automatically from its main power source to a backup power source once it detects a power outage within the primary source. |
The main function of STS is to transmit critical loads in between two separate AC power sources without any interruption. |
|
ATS switches are available in two types circuit breaker & contactor. |
STS switches are available in two types single phase & three-phase. |
|
STS has no break within supply throughout the transfer. |
ATS has a short ms break within supply throughout the transfer. |
Types of Automatic Changeover Switches

-
Open Transition ATS
The Open Transition ATS disconnects the load from the primary source before connecting it to the backup source.
-
Closed Transition ATS
A Closed Transition ATS eliminates power interruptions by momentarily overlapping the two power sources during the transfer. This makes it ideal for critical systems, such as medical facilities, data centers, and industrial processes where even a fraction of a second of power loss can have significant consequences.
-
Static Transfer Switches (STS)
Static Transfer Switches use advanced solid-state components to perform ultra-fast transfers, often within milliseconds.
-
Modular ATS
The Modular ATS provides flexibility and scalability, thus being an ideal solution for large or complex facilities.
