FAQ
If you’re wondering how simple voltage regulation can overcome huge voltage anomalies, you’re not alone. There is a sea of information online explaining how voltage stabilisers work. However, not many are comprehensive enough to explain the in’s and out’s of what exactly goes on within these innovative works of wonders.
For servo electronic design voltage stabilisers:
- Any form of erratic or unstable input voltage is immediately detected by microprocessors in the voltage stabiliser.
- This triggers the servo motor driver to instantly activate and move the servo motor’s shaft across the windings of a variable transformer – AUTOMATICALLY adjusting the output voltage value to your desired prescribed limit.
- The regulated voltage is then supplied through the secondary of the Buck-Boost Transformer, and then fed to your load equipment or appliances in use.
For the full in-depth literature with quantitative and qualitative research explaining all the how’s and why’s, download our complimentary 22-page PDF white paper to learn more.
For Servo Electronic Voltage Stabilisers, maintenance is absolutely minimal. Quarterly checks on metering displays and yearly ocular (visual) inspections are strongly encouraged. Any electrically trained technician is more than capable of carrying out these simple maintenance tasks – with ease.
For a virtually maintenance-free solution, explore our Extra Robust Magnetic Induction design that’s engineered for maximum uptime protection.
Yes. Ashley Edison is an ISO 9001:2015 Certified organisation.
With a wealth of manufacturing experience acquired over 40 years, Ashley Edison powers on, and harnesses its industry-certified expertise to craft world-class products to perfection.
Spread across three offices worldwide, we operate as a single integrated powerhouse—fully outfitted with full-stack in-house product design, prototyping, and manufacturing teams to meet your unique needs.
Equipment failures can be frustratingly painful to deal with. Severe voltage drops and heavy voltage fluctuations from the mains – are some of the culprits crippling your uptime.
The fastest and most cost-efficient method (also adopted by Grid Operators and MNCs) is to incorporate a dependable voltage regulating solution into your electrical system.
This facility-saving quick fix eliminates all forms of harmful voltage irregularities, drops and fluctuations – regardless of load change in your electrical system.
An optimally stabilised output voltage supply provides robust protection for your high value equipment.
What you’re looking for is an answer that guarantees improved operational efficiency, reliability, prolonged healthy lifespan and ultimately, a solution that safeguards your precious uptime – permanently.
Need help picking the perfect voltage regulating solution? Speak to us today! Our consultants are happy to assist you with your challenges – every step of the way.
When it comes to mission-critical applications and high value equipment, an uninterruptible power supply (UPS) is used for backup power when your regular power source fails.
If you’re anything like us, you’d believe that leaving things to chance is not practised in the electrical engineering community.
Which is why we too, believe in redundancy systems.
Supplying voltage stabilisers to mission-critical applications like datacenter and IT system infrastructures has become a crucial part of uptime protection in the industry.
Should the UPS require any form of shut down or scheduled maintenance, you can be assured that your voltage stabiliser continues to deliver clean, stable voltage supplies to your load, all day, everyday.
There are 4 different types of voltage stabiliser designed for commercial and industrial applications: Servo Electronic, Magnetic Induction, Static Tap Switching, Solid State (Ferroresonant).
Each design has its pro’s and con’s. While Servo Electronic based Voltage Stabilisers have mainly dominated the market, the ever growing demand for uncompromising reliability and maximum durability in voltage protection has caused an unsurprising shift towards the Magnetic Induction design.
Static tap switching design (thyristor based) is favoured by non critical projects that are desperately constrained by budgets. When technical specifications are written under non stringent requirements (e.g. voltage output of ±10%), cheaper prices may be preferred over quality.
Solid State Design (ferroresonant) is highly dependable. With no moving parts, the ferroresonant voltage stabiliser is not subject to mechanical wear and tear. Due to its nature, it is typically suitable for single phase applications.
To learn more on which design is ideal for your application, read our comprehensive blog article (11min read) to find out more.

Ashley Edison Automatic Voltage Stabilisers are designed as “Plug-And-Forget” voltage protection solutions.
Once commissioned, the incoming voltage is INSTANTLY regulated to your desired set output voltage values within 1.5ms.
Voltage levels are automatically and constantly maintained during the day when loading is high, and throughout the night when loading is low – giving you a peace of mind and unstoppable confidence that your equipment are well taken care of, with no guesswork needed.
At Ashley Edison Global, we believe in engineering solutions that are built to last. 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 when product design quality is concerned.
In our manufacturing process, every product is closely inspected as they pass through assembly lines with an intense focus on durability and maintainability—while paying close attention to safety as a top priority.
With over 40 years of research and development, Ashley Edison products have been put through the test of time, enabling us to break boundaries by greatly improving MTBF and total dependability. This results in the perfect marriage of performance and reliability.
Our industrial and commercial clients from over 104 countries around the world have achieved a constant stable and clean power supply after successful installation of our products, and there are no reported operational issues to date since 2012.
Despite unfavourable weather conditions, your AVR should last you a lifetime – if you take good care of it.
Being said, our philosophy of building lasting voltage solutions is proven to stand the test of time, through this proven case study below:
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 and simple process, we ensure that our products run smoothly throughout their expected healthy lifespan, with absolute certainty and maintainability.
Every Ashley Edison Automatic Voltage Stabiliser comes inclusive of 3-Year full warranty on all parts.
