UK Manufactured UPS Bypass Switches

Finding the Right Distributor

Most UK providers act as middlemen. When you choose APS, you are partnering directly with the original equipment manufacturer (OEM). This direct relationship eliminates the knowledge gap and provides three distinct operational advantages:

•  Bespoke Engineering for Complex Sites: Standard switches often struggle with non-standard environments. Because we own the manufacturing process, we can customise the build to your exact requirements. Whether you need an integrated Castell Interlock or a completely bespoke panel, we can build it to your specification in our 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, we control our own production schedules and maintain high stock levels of core components, allowing us to meet tight project deadlines that others can't.
• Direct Technical Ownership: Our support comes from the same team that designed the schematics. You aren't calling a general helpdesk; you are speaking to experts who understand the internal circuitry of the UPS bypass switches they install on a daily basis.

Failsafe Engineering

In a high-stakes environment, such as a hospital, data centre, or continuous manufacturing plant, human error is the greatest threat to uptime. Our switches are engineered with fail-safes that go beyond the industry minimum:

1. Make-Before-Break (MBB) Technology

The transition between UPS inverter power and raw mains must be seamless. Our MBB technology ensures that the contactors overlap during the transfer. This ensures there is never a break in the circuit, preventing the momentary power dip that can crash sensitive servers or medical equipment.

2. Castle Key Interlocking

We often advocate for the use of physical safety systems. Castle 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, we remove the risk of dropping the load due to a moment of distraction.

3. Industry-Leading 5-Year Warranty

We offer a 5-year warranty on our entire bypass range, a testament to the high-grade components and rigorous UK-based testing every unit undergoes before it leaves our floor.

Quality You Can Trust

We don’t just claim quality; we prove it through a rigorous framework of industry-leading accreditations. As an ISO 9001 and 14001-certified manufacturer, our Andover facility operates under strict quality and environmental management systems, ensuring that every switch is built to a repeatable, world-class standard. 

Whilst our status as an ECA Registered member and a SafeContractor accredited partner means our engineering teams adhere to the highest technical and professional safety benchmarks in the UK. 

This level of oversight is why we can confidently offer a 5-year warranty on our entire bypass range - a guarantee backed by high-grade components and meticulous UK-based testing. 

Sustainability & Social Value

Partnering with a UK-based manufacturer like Adept Power brings significant environmental and social benefits. By choosing an APS bypass switch, you are actively reducing the carbon miles associated with your infrastructure and eliminating the high environmental cost of international shipping. 

Our ISO 14001 certification guarantees that your equipment is produced under a strict environmental management system dedicated to waste reduction and resource efficiency. Choosing a UK OEM supports the local economy and helps bridge the engineering skills gap through our commitment to apprenticeships and local employment. 

As a business focused on environmental, social and governance, we ensure our bypass switches are part of a commitment to 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 ensures that when your UPS needs attention, your business stays live. As we've detailed in our guide on understanding UPS bypass switches, quality at the installation stage prevents catastrophe at the maintenance stage.

Frequently Asked Questions

Do APS switches work with other UPS brands?

Yes. Our switches are brand-agnostic. Whether you use Riello, Eaton, APC, or Vertiv, our hardware integrates seamlessly. This means if you upgrade your UPS in the future, you don’t 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 safely work on the UPS. An automatic bypass (often found in an ATS) facilitates an instant, hands-free transfer if the UPS itself develops an internal fault. Learn more about the importance of these switches here.

Can you provide on-site commissioning?

Absolutely. Beyond manufacturing, our nationwide team of engineers can provide site surveys and installation to ensure your bypass system is perfectly synchronised with your UPS.
