In power management systems, an ats switch is often considered an essential component. In the event that there is a disruption in the primary source of power, such as a utility grid, it is designed to automatically transfer electrical load to a backup power source, such as a generator, in the event that there is a disruption in the primary source of power. This ensures that critical systems and equipment continue to operate without interruption, hence reducing the amount of time spent in downtime and reducing the possibility of financial losses.

Moreday is an industry leader in dual mains switching equipment (atse), in the design of solutions, and has more than 15 years of experience in manufacturing and distribution. The company was established in 2009.

A standard warranty of two years is included with each and every ats. When there is a problem with our product, our team will provide feedback on the solution within twelve hours, and the engineer will be able to solve the problem within the time frame that was previously agreed upon.

Types Of Ats Switch

Open transition ats switches and closed transition ats switches are the two primary types of ats switches. In the course of the transfer, open transition switches will momentarily disconnect the load from both power sources; on the other hand, closed transition switches will provide a smooth transition in which the load will experience no interruptions whatsoever. The selection of one of these kinds over another is determined by the precise necessities and prerequisites of the application.

The mysterious pc-level automatic transfer switch domain is home to the mysterious pc-grade auto-switching mechanism, which consists of a dual power supply that chooses a load switch that does not contain an over current release as the motivating force. This system does not have any protective characteristics, but it has a large tolerance and excellent connecting capabilities, which ensures the switch’s safety and resistance to malfunctions such as overloads and short circuits. As a direct consequence of this, a reliable connection circuit has been established.

Confusion surrounding the class cb bifurcated energy origin: A dual power supply that is outfitted with over current release, which allows its primary contact to connect and disrupt any currents that are being delivered through a short circuit.

Within the domain of the class cb automatic transfer switch, the dual power supply ought to opt for a circuit breaker that is exclusively equipped with a short-circuit current release as the actuator. This system has a selective protective function, which protects against short circuits for lower loads and cables. This protection is provided by the system. Its ability to form and sever connections is significantly superior to those of alternative components such as contactors and relays in almost every respect.



Choose a model that has both a temperature and dual power switch if you want to maximize your level of protection.


Ensure that the voltage remains within the safe range at all times while the operation is in progress.

ATS Switch transfers electrical loads between primary and backup power sources, ensuring continued operation of critical systems during power outages.
There are two main types of automatic transfer switches: open-circuit switching and closed-circuit switching. An open transfer switch temporarily disconnects the load during the transfer process, while a closed transfer switch provides seamless transfer without any interruption.
The lifespan of a generator automatic transfer switch may vary depending on the frequency of use and quality of maintenance. Typically, well-maintained automatic transfer switches will last 15 to 20 years or more.
MOREDAY’s ATS switches have passed CE,IEC, IEEE, ROHS and other certification standards, which can ensure the reliability and performance of ATS switches. You can rest assured to purchase it for your enterprise or application.
Yes, MOREDAY can provide you with customizable ATS switches based on your specific requirements, with various rated voltages and frequencies, as well as other features to meet your specific needs.
Automatic Transfer Switches (ATS) detect main faults primarily by continuously monitoring supply voltage and frequency. This is how it usually works:
Voltage Sensing: ATS devices continuously measure the input voltage from the main supply. If the voltage falls below a preset threshold, ATS interprets this as a power failure.
Frequency Sensing: In addition to the voltage, the frequency of the power supply is also monitored. A significant drop or increase in frequency may indicate power instability, prompting the ATS to initiate a switch to backup power.
Delay: To avoid unnecessary switching due to brief power fluctuations, ATS units often have a delay feature. This ensures that switching only occurs when voltage or frequency anomalies persist for longer than a certain time, confirming a true power failure.
Control logic: ATS includes control logic for analyzing sensed data and making decisions. If a fault is detected, control logic activates a switching mechanism to switch power from the mains to a backup generator, ensuring power continuity.
To properly maintain your automatic transfer switch (ATS) and ensure its reliability and longevity, you can follow these recommended practices:
Regular Inspections and Tests: Schedule regular inspections and functional tests of the ATS to ensure it is functioning properly when required. Testing typically involves simulating a power outage to verify that the ATS activates correctly and transfers load without issue.
Mechanical Inspection: Inspect all mechanical parts of the ATS for signs of wear or damage. This includes checking for loose connections, making sure all moving parts are lubricated, and replacing any worn or defective parts.
Electrical connections: Regularly check and tighten electrical connections. Loose connections can lead to poor performance and even safety risks.
Cleanliness: Keep the ATS and its environment clean and free of dust and debris that could interfere with proper mechanical and electrical functionality.
Regular maintenance not only ensures the ATS operates effectively during outages but also extends its lifespan, protecting your investment in critical power infrastructure.
Installation requirements for automatic transfer switch for generators generally involve several key considerations to ensure proper functionality and safety:
Electrical Compatibility: The ATS must be compatible with the voltage and current specifications of the generator. It is important to match ATS capacity to generator output to handle the load efficiently.
Physical Space: Sufficient space must be allocated to the ATS to ensure adequate space for installation and future maintenance activities. The space should be accessible and safe.
Environmental Conditions: The installation area should be clean, dry, and well-ventilated to prevent the ATS from being exposed to dust, moisture, and extreme temperatures that could affect its performance.
Wiring and Connections: Proper wiring and safe connections are critical. This includes ensuring that all wiring meets electrical codes and standards and has correct phase orientation and grounding.
Professional Installation: Installation by a qualified electrician or professional installer is highly recommended to ensure safety and compliance with local electrical codes and standards.
Testing and Commissioning: After installation, the ATS should be thoroughly tested to confirm that it operates properly on both mains and generator power. This testing should include manual and automated transmission testing.
Local Codes: Local building and electrical codes must be followed, and in some cases, a permit may be required before installation of the automatic transfer switch for generator can begin.
