Types of ATS panels 

The ATS panel (Automatic Standby Switching) is an electrical device designed to provide uninterrupted power supply by automatically switching between the main and backup power sources. It is most often used in systems with diesel or gasoline generators.

ATS panels can be classified according to several criteria:

By capacity

•Small panels – up to 16-63A, suitable for home and office applications.

•Medium panels – 63-250A, used in commercial facilities and small industries.

•Large panels – over 250A, for industrial facilities, hospitals, hotel complexes, etc.

By type of control

•Mechanical/elementary ATS – with relays and contactors without an intelligent controller.

•Microprocessor ATS – with programmable controllers and displays.

•Smart ATS – with remote control capabilities (GSM, Ethernet, Wi-Fi), event and parameter recording, alarm notifications.

By installation method

•Standalone panel – separate from the generator.

•Integrated panel – built into the generator housing.

Advantages of using an ATS panel

Using an ATS panel provides a number of important advantages:

Automaticity

No human intervention is required in the event of a network outage – the system reacts instantly and turns on the generator.

Seamless and safe switching

Switching between the network and the generator is safe, without the risk of short circuits or reverse current.

Reliability

In critical environments (hospitals, data centers, telecommunications), ATS is essential to guarantee uninterrupted power supply.

Equipment protection

The controller monitors the parameters and prevents the generator from starting under dangerous conditions (e.g. low oil, overheating, etc.).

Energy efficiency

Allows precise control over the generator’s operating time and prevents unnecessary engine wear.

ATS panel applications

ATS panels are used in all areas where reliability of power supply is required:

•Homes and villas – to protect appliances, heating, cameras and other important consumers.

•Offices and business buildings – to ensure uninterrupted operation of IT systems, communications and security.

•Hospitals and healthcare facilities – where any interruption can endanger human lives.

•Industry and manufacturing – to prevent production losses.

•Hotels, shopping centers – for uninterrupted service to customers and systems.

Installation and maintenance

Installation requirements

The installation of the ATS panel must be carried out by qualified electricians. Basic requirements:

•Correct sizing according to the load;

•Safe grounding;

•Distances from moisture and dust;

• Availability of short-circuit and overload protection.

Maintenance and testing

To function reliably, the system must be tested periodically:

• Functionality check (simulation of network failure);

• Checking the controller batteries (if any);

• Assessment of the condition of the contactors and connections;

• Reviewing logs and alarm messages.

The selection, installation and maintenance of ATS must be done with professionalism, because the stability of the entire power supply process depends on them. With the advent of new technologies, these panels are becoming intelligent systems that not only perform functions, but also analyze, predict and manage the energy flow with unprecedented accuracy and security.
