British Born and Bred 🇬🇧

Founded in a small town against the backdrop of industrial, post-war Britain, Ashley Edison Global began life as a supplier of basic electrical components such as circuit breakers and cables.



Currents of Change

Fully cognisant of the erstwhile lack of power quality in the U.K., Ashley Edison Global made the strategic call to pivot into voltage control solutions. By outfitting manual variable transformers with servo motors, we found an ideal solution to the power challenges faced by both industrial and residential sectors.



Rising Demand and Rapid Innovation

Ashley Edison Global experienced soaring demand from both businesses and government in the UK and EU. Driven by our core vision to create tomorrow’s electrical products, today, we constantly improve on our product design with the addition of more protection features. Furthermore, by harnessing the power of servos—considered to be cutting-edge technology at the time—we rose to become a market leader in automated power protection, establishing ourselves as the default go-to solution for voltage protection.



🇹🇼 Pivot to East Asia

To meet skyrocketing demands for our products overseas, especially in the East Asian market, we swiftly expanded eastwards, establishing our machinery manufacturing hub in Taiwan—famed since the mid-20th century as one of the Four Asian Tigers for its economic success, spirit of innovation, and manufacturing expertise.



Birth of a New Chapter 🇸🇬

Having secured a strong presence in Greater China, we turned our attention southwards. Drawn to Singapore for its world-renowned efficiency, reliability, and impeccable reputation as an international financial center, we established our Asia-Pacific headquarters in the Southeast Asian city-state—the first outside of the UK—to better serve our numerous clients in this rapidly flourishing region.



🌎 Engineering a Global Reputation

From the United Nations and U.S. military, to global tech and oil giants—the scale and diversity of our clientele speaks volumes to the stability, reliability, and versatility of our customised product offerings. While we’ve always operated on a lean marketing budget, our stellar global reputation is testament to the fact that our reputation precedes us.



A Vision for the New Decade

Out of a generation of uncertainty, comes a new era of voltage stability. Amid the myriad challenges collectively faced by humanity in this new decade, our time-tested resilience as an organisation shines through. Presently dual-headquartered in the U.K. and Singapore, Ashley Edison Global endures as a symbol of power protection and stands ready to safeguard your operations well into the 21st century and beyond.



Engineered to Endure

At Ashley Edison Global, we believe things should be built to last.


This is especially true with high-value equipment and mission critical assets. By championing the need to optimise rather than replace, we safeguard the maintenance budgets of our clients by preventing unnecessary expenditure on replacements or repairs.


No detail is too small where product design quality is concerned. Every product is closely inspected as they pass through the assembly line with an intense focus on functionality—paying close attention to our customers’ needs of smaller footprint designs in space-limited environments while maintaining safety and convenience as a top priority with sufficient room for any future maintenance work. 

Optimising the Present, Empowering Tomorrow

We’re committed to creating effective plug-and-forget power solutions that stand the test of time.


At Ashley Edison Global, our vision to bring our power quality and voltage optimisation solutions to every organization is backed by an unwavering dedication to well designed, industry-certified solutions that deliver voltage stability, with certainty.


In an industry where technology trumps tradition, we strive to truly understand and meet our clients’ every need through the manufacturing of small quantities of highly customized products. Refined to perfection, our spirit of customer-centric innovation has only grown with the company over the last 40 years.

Simple is Clever

Everything connects back to one of our core principles—simplicity in design.


Believing that less is indeed more, we eliminate all superfluities in the design of our products, allowing only what’s absolutely necessary to shine brilliantly. Simple engineering designs are more likely to be understood, less likely to fail during prototyping, easier to perfect during the product testing phases, and more successful at helping our customers optimise their operations.

Intuitive Form and Function

We believe that good engineering design speaks for itself.


By creating intuitive products that are easy to grasp and use, our clients can easily gain a thorough understanding of our solutions with little effort.


Our product usability translates into our client’s all-around success for power optimisation, through features that are intelligently paired with solid engineering design and functionality.

Tested For Reliability

From the scorching heat of the Arabian Desert to the sub-zero temperatures of the Caucasus Mountains, our products have been put to the test in the harshest environments—and through rigorous factory testing processes, we anticipate and eliminate every possible source of imperfection.


In our constant pursuit of perfection, we perform detailed risk analyses to examine the benefits and drawbacks of different designs, before implementing customised solutions to reinforce the robustness of our Automatic Voltage Stabilisers. This greatly increases the lifespan of our products, making them the perfect choice for those seeking absolute reliability in their power protection solutions.

Ease of Maintenance

We design intuitive products with simplicity and ease-of-use in mind, eliminating the chore of complex disassembly and reassembly—especially in circumstances that merely require the replacing of minor components. By making regular inspections a straightforward process, we ensure that our products run smoothly throughout their expected lifespan, with absolute certainty.

Built to Last

Our Test Engineers conduct frequent quality assurance inspections, ensuring detailed testing at every stage of development and manufacturing. Over the decades, we’ve reviewed and revised our manufacturing process thoroughly and consistently, taking into account past diagnostics data to improve our next-generation AVR models. This results in the perfect marriage of performance and reliability.



Plugging into the
Power of Green

At Ashley Edison Global, we believe in helping to engineer a more sustainable tomorrow for our clients, partners, and ultimately the planet.


In pursuit of this vision, we ensure that each part of our manufacturing process and infrastructure complies with green energy goals—empowering organisations worldwide with optimised energy efficiency and a reduced carbon footprint.


From brownouts to severe voltage fluctuations, Ashley Edison takes care of all your power needs by delivering optimised, stable voltage supply to your electrical system.
