Automatic Transfer Switches (ATS) for Reliable Power Backup
An Automatic Transfer Switch (ATS) is used to automatically switch power supply between a primary source and a backup source, ensuring continuous power without manual intervention. It is widely used in power distribution systems, generators, and renewable energy setups.

How to Select the Right ATS for Your Application
When the main power supply fails, the ATS automatically detects the interruption and switches to the backup source (such as a generator). Once the main power is restored, it switches back automatically.

Knowledge About MCB
- What is an ATS?
An automatic transfer switch (ATS) is a device that automatically transfers a power supply from its primary source to a backup source when it senses a failure or outage in the primary source.
- How does an automatic transfer switch work?
When it detects an interruption or anomaly (such as undervoltage, overvoltage, or phase loss), it sends a signal to the backup generator to start. Once the generator reaches optimal operating conditions, the switch automatically transfers the load to the secondary power source.
- What is the difference between ATS and manual transfer switch?
An automatic transfer switch operates without human intervention, while a manual transfer switch requires an operator to initiate the transfer.
- Where is ATS used?
Applicant tracking systems are used by a wide range of people involved in the hiring process.
- How to choose ATS current rating?
ATS Rated Current = Maximum Load Current × Safety Factor (1.25–1.5); this value should then be adjusted upward as appropriate, taking into account the specific load characteristics.
If you can provide specific power ratings or application scenarios (such as EV charging stations or energy storage systems), I can help you directly determine a suitable model.
