Types of ATS panels 

The ATS (Automatic Start and Stop) panel is a key component in backup power systems, especially when it comes to diesel generators. They can be classified according to various criteria, including their functions, size, type of application and level of complexity.

Single-phase and three-phase

Depending on whether the generator and consumers are single-phase (230V) or three-phase (400V), the panel is designed accordingly.

Mechanical or electronic

Mechanical ones use relays and contactors, while modern electronic ATS panels rely on microprocessor controllers with a display and finer settings.

With built-in or external control

Some ATS panels are built into the generator housings, while others are installed separately in the building’s electrical panel.

Advantages of using an ATS panel

Automation and convenience

The user does not have to take any action – the system reacts on its own in the event of a power failure.

Protection of sensitive equipment

In the presence of electronic devices, servers, security systems, etc., even short interruptions can lead to damage or loss of data. The ATS panel prevents this.

Increased safety

Switching between the grid and the generator occurs without the risk of backflow or short circuit.

Time savings

Especially important for industrial sites, where the response time to an interruption can lead to production losses.

Reduction of human error

Automation eliminates the need for manual start/stop, which can lead to delays or incorrect actions.

How to choose a suitable ATS panel?

When choosing an ATS panel for a diesel generator, several main factors must be taken into account:

Generator and load power

The panel must be consistent with the nominal power of the generator, as well as with the consumers it will power.

Number of phases

It is important to know whether the system is single-phase or three-phase.

Generator type

Some modern generators have their own control module, which may require a special type of communication with the ATS panel.

Additional features

– LCD display

– Remote control

– GSM notification capability

– Ethernet connectivity for monitoring

Brand and quality

Choosing an established manufacturer guarantees better performance, reliability and maintenance.

Installation and maintenance

Installation of an ATS panel should only be performed by qualified electricians. This includes:

•Connection to the mains and generator power

•Controller configuration

•Setting timers and thresholds

•Automatic transfer tests

Maintenance

•Periodic tests – network failure simulation

•Checking contacts and cable condition

•Functional testing of relays and protections

•Viewing logs (for electronic models)

Proper selection, quality installation and regular maintenance of the ATS panel guarantee long-term and trouble-free operation of the entire system.
