UK Manufactured UPS Bypass Switches

A UPS is a critical asset, but it should not become a single point of failure.

Whether you need routine battery replacement, a firmware update or an emergency repair, being able to isolate your UPS without dropping the load is vital.

While many suppliers offer generic imported bypass switches, Adept Power Solutions takes a different approach by designing and building them in-house.

Choosing a UK-manufactured APS bypass switch provides a level of engineering control and operational security that off-the-shelf alternatives cannot match.

Finding the right distributor

Most UK providers act as middlemen.

When you choose APS, you are working directly with the original equipment manufacturer.

This direct relationship removes the knowledge gap and provides three clear operational advantages.

Bespoke engineering for complex sites

Standard switches can struggle with non-standard environments.

Because APS owns the manufacturing process, the team can customise the build to meet exact requirements.

Whether you need an integrated Castell interlock or a completely bespoke panel, APS can build it to specification at its Andover facility.

UK supply chain agility

In an era of unpredictable global logistics, waiting 12 weeks for a switch from overseas is rarely an option for a critical project.

By manufacturing in the UK, APS controls its own production schedules and maintains high stock levels of core components.

This allows the team to meet tight project deadlines that others cannot.

Direct technical ownership

APS support comes from the same team that designed the schematics.

You are not calling a general helpdesk. You are speaking to experts who understand the internal circuitry of the UPS bypass switches they install every day.

Failsafe engineering

In high-stakes environments such as hospitals, data centres and continuous manufacturing plants, human error is one of the greatest threats to uptime.

APS switches are engineered with failsafes that go beyond the industry minimum.

Make-before-break technology

The transition between UPS inverter power and raw mains must be seamless.

APS make-before-break technology ensures that the contactors overlap during transfer.

This means there is no break in the circuit, helping prevent the momentary power dip that can crash sensitive servers or medical equipment.

Castell key interlocking

APS often advocates the use of physical safety systems.

Castell key interlocking ensures that an engineer physically cannot turn the switch in the wrong sequence.

By requiring a key to be released from one state before it can be used in the next, the system removes the risk of dropping the load due to a moment of distraction.

Five-year warranty

APS offers a five-year warranty on its entire bypass range.

This reflects the high-grade components and rigorous UK-based testing that every unit undergoes before it leaves the facility.

The APS range at a glance

Typical imported switches are usually overseas-built and mass-produced.

They tend to offer limited customisation, lead times that depend on global freight, standard 12 to 24-month warranties and compatibility that may be limited to specific brands.

APS-manufactured switches are UK-designed and assembled, with bespoke enclosures and sockets, rapid UK-wide delivery, a five-year warranty and brand-agnostic compatibility across all UPS systems.

Solving the space problem

Plant rooms and server racks are becoming more crowded.

APS has designed its range to solve the question of where the bypass switch will fit.

Rack-mounted units

Compact 19-inch units are designed for easy integration into standard IT racks.

Wall-mounted units

Space-saving, rugged wall-mounted solutions are available for plant rooms where floor space is at a premium.

3/1 phase specialist units

APS specialises in 3-phase input to single-phase output configurations.

This is a niche but vital requirement for many UK facilities.

Mounting types and applications

Rack-mounted 1/1 phase units, available as IEC or hardwired options, cover 10A to 80A and are ideal for data centres and IT racks.

Wall-mounted 1/1 phase units cover 16A to 160A and are suited to comms rooms and small offices.

Wall-mounted 3/1 phase units cover 32A to 160A and are designed for sites with a 3-phase supply running 1-phase loads.

Wall-mounted 3/3 phase units cover 32A to 630A and are suitable for industrial and large-scale infrastructure.

Quality you can trust

APS does not simply claim quality. It proves it through a rigorous framework of industry-leading accreditations.

As an ISO 9001 and ISO 14001-certified manufacturer, the Andover facility operates under strict quality and environmental management systems.

This helps ensure every switch is built to a repeatable, world-class standard.

APS is also an ECA Registered member and a SafeContractor accredited partner, meaning its engineering teams follow high technical and professional safety benchmarks in the UK.

This level of oversight is why APS can confidently offer a five-year warranty across the entire bypass range, backed by high-grade components and detailed UK-based testing.

Sustainability and social value

Partnering with a UK-based manufacturer such as Adept Power brings environmental and social benefits.

Choosing an APS bypass switch helps reduce the carbon miles associated with infrastructure and avoids the environmental cost of international shipping.

The company’s ISO 14001 certification confirms that equipment is produced under a strict environmental management system focused on waste reduction and resource efficiency.

Choosing a UK OEM also supports the local economy and helps bridge the engineering skills gap through apprenticeships and local employment.

As a business focused on environmental, social and governance principles, APS ensures its bypass switches form part of a more sustainable and socially responsible supply chain.

Eliminate your single point of failure

A bypass switch is the safety net for your safety net.

Investing in a UK-built APS unit helps ensure that when your UPS needs attention, your business stays live.

As explained in Adept Power’s guide to understanding UPS bypass switches, quality at the installation stage helps prevent serious issues at the maintenance stage.

Frequently asked questions

Do APS switches work with other UPS brands?

Yes. APS switches are brand-agnostic.

Whether you use Riello, Eaton, APC or Vertiv, APS hardware integrates seamlessly.

This means that if you upgrade your UPS in the future, you do not have to replace your bypass infrastructure.

What is the difference between a manual and an automatic bypass?

A manual bypass is used for planned maintenance, allowing an engineer to work safely on the UPS.

An automatic bypass, often found in an ATS, enables an instant, hands-free transfer if the UPS develops an internal fault.

Can APS provide on-site commissioning?

Yes.

Beyond manufacturing, APS has a nationwide team of engineers who can provide site surveys and installation to ensure the bypass system is properly synchronised with the UPS.
