Suyang Automatic Transfer System

Suyang Automatic Transfer System, Yangzhou Suyang Electric Co., LTD has proudly stood the test of time since its establishment in 2006. The mission of Suyang is become a leading company in providing outstanding ATS (the automatic transfer switching equipment) at a fair price. Its integrity is never compromised and it makes a positive contribution to society. Suyang creates partnerships to better connect with their customers. Therefore Suyang will support their dealers at national and regional trade show events to promote awareness of their products in the market place. It place a strong emphasis of its products on quality. All equipment will be inspected and tested, which should be conformed to its own quality standards, like "CCC", "CE", "ROHS" and so on.

What's more?

Low-voltage automatic transfer switch assemblies provide a reliable means of transferring essential load connections. Moreover It is between primary and alternate sources of electrical power. Data centers, hospitals, factories and a wide range of other facility types that require continuous or near-continuous uptime. Typically utilize an emergency (alternate) power source such as a generator or a backup utility feed. But when their normal (primary) power source becomes unavailable.

An automatic transfer switch (ATS) is a self-acting, intelligent power switching device governed by dedicated control logic. The principal purpose of an ATS is to ensure the continuous delivery of electrical power from one of two power sources. But to a connected load circuit (electrical equipment – lights, motors, computers, etc.).

Automatic Transfer Switches (ATS) connect facilities to backup power without human intervention. ASCO Power Technologies offers a range of ATS to improve power availability. With products that easily transfer loads between utility and backup power sources. ASCO ATS are listed to UL 1008 and designed to work with virtually any generator. Browse our ATS products to find a unit to support applications from commercial businesses to mission-critical facilities.

Advantages of a automatic transfer panel

  • You need to switch it every time the mains fails and you want to run the generator.
  • You need to start the generator manually each time.
  • If you aren't nearby, you cannot start the backup power.
  • It takes longer - the automatic panel can react as soon as the mains fails.

Automatic Transfer Switch (ATS) is used which operation voltage is no more than 660VAC, and may transfer with load. The ATS rated current series is 40A, 63A, 80A,125A, 160A, 250A, 400A, 630A, 800A, 1000A, 1250A, 1600A, 2000A to 4000A, be divided up two types with 3 poles and 4 poles. The ATS of 40~125A is defined with ‘N’; 160~400 is defined with ‘T’; 630A~2000A is defined with “M”. Above 2000A is also available.


Automatic Transfer Switch can automatically transfer load from mains power to emergency power without operator intervention. When mains power fails or voltage drop below 80% of normal voltage, the ATS will start emergency generator, after a preset time of 0 to 10 seconds(adjustable). At rated speed, the ATS will transfer load to emergency power with available size ranging from 40A to 4000A. There is a switch suitable for every project’s need.


ATS is an integral part of the power generation process, allowing smooth and immediate transfer of electrical current between multiple sources and the load. When the generator is operating, the transfer switch prevents dangerous feedback of current to the utility’s system. It also ensures that different power sources are fully synchronized before their power is combined or loads are transferred, which is imperative for safe operation.


The transfer switch senses when utility power is interrupted, and starts up the generator if the utility power remains absent. In about five to ten seconds, when the generator is producing full power, the transfer switch disconnects the load from the utility and connects it to the generator, restoring electricity to the load. The transfer switch continues to monitor utility power, and when it is restored, switches the load from the generator back to the utility. Once the generator is disconnected, it goes through a cool-down routine and is automatically shut down.


Choosing the right ATS for the generator set:


1. Generator Set Current: =Genset KVA*1000/Voltage/1.732

2. ATS Size should be 120% of the generator set current.




1. For emergency power usage in building, auto transfer switch(ATS) is essential. ATS can auto transfer load from mains power supplying to emergency power.

2. When the main power supplying failure or voltage drop below 80% of normal voltage, ATS will auto start emergency generator set after a preset.

3. Time of 0 – 10 sec (adjustable according to the users). Once generator reach at rated speed, the ATS will transfer the load to emergency generator sets automatically.

4. The ATS has large variety current.
