ATS Panels

What are ATS Panels, and what role do they play in a standby power system?

Automatic mains failure (AMF) panels – now referred to as automatic transfer switch (ATS) panels – make the power switch to emergency standby generators in the event of a significant loss of mains power or total blackout. Without AMF panels / ATS panels, generators need to be operated manually, which could result in loss of data, damage to electrical equipment, and huge disruptions. An uninterruptible power supply (UPS) system bridges the changeover switching gap between mains power and your backup generators and back again and is usually installed downstream of the ATS panel.

What is an ATS Switch?

A low voltage automatic transfer switch provides a reliable means of transferring load connections between primary and alternative sources of electrical power, such as transferring from mains power to a generator. Locations that cannot afford any loss of power such as hospitals and data centres are able to utilise an ATS to automatically switch to an alternative electricity source in an emergency.

How does an Automatic Transfer Switch (ATS panel) work?

ATS panel will monitor the incoming AC mains supply, activate the standby generator when mains power fails, and make an automatic electrical transfer of the building’s load from the mains to the generating set. When the mains supply returns, the ATS panel controls a return to the mains supply and shuts down the generator after a suitable cooling run.

ATS Panel Design and Manufacture

We design and manufacture our own ATS panels, often as part of a turnkey standby power solution that links an automatic transfer switch, UPS and standby generators with remote monitoring and associated security and safety features.

With many years’ experience providing AMF panel solutions, our latest ATS offering, Phoenix2 is a fully automatic transfer panel that can be used for either mains to generator or mains to mains applications.

It includes all mains and generator power monitoring and protection systems with a Motorised four pole changeover switch conforming to BS EN 60947-6-1, operated by a digital programable ATS controller, which can be programmed for either dual mains or mains to generator applications. This purpose-built ATS panel is a single unit that does not contain contactors and circuit breakers, reducing the likelihood of component malfunction and allowing flexibility if the power or control design changes.

ATS Panel Phoenix2 Meets BS8519 Standards

Our Standard Phoenix2 ATS panels have an AC-33B rating. This stringent requirement is part of the British standard BS8519 for fire-resistant power and control cable systems. BS8519 ensures that life safety equipment such as firefighter lifts, emergency lights, smoke extraction fans and other critical applications are supported to a national standard. All Shenton Group Phoenix2 ATS panels meet these requirements.

Shenton Group ATS Panel Range

Our Phoenix2 ATS panels are available as single-phase and three-phase. Single-phase is typically used in residential property and can support 40 Amp- 125 Amps of power, and three-phase ATS panel support 40 Amp – 3200 Amp and are typically used in commercial property. Other sizes are available on request.

As standard, our ATS panels come with volt free contacts and indicators for remote monitoring or BMS system connections. This will enable you to see which power supply is available and which supply is online.

Bespoke ATS Panel Solutions

Every building is different, and the life safety equipment requirement varies. Shenton Group will work with you to establish your requirements and design a solution fit for your unique needs.
