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 the machinery or appliances in use.

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, every day.

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.

Stay Safe With Greater Protection

As safety is our utmost priority, Ashley Edison prepares for every scenario possible
—taking the puzzle out of your protection.

Designed And Engineered With Safety In Mind

We leave nothing to chance when it comes to larger capacity units (≥400KVA). By installing high-quality protective acrylic shields in front of live parts, we ensure the safety of your personnel at all times. For enhanced protection during installation, all distances between uninsulated metal parts, busbars, and cable sizes are compliant with IEC61439-1 and IEC 61439-2 guidelines.

Outfitted with fireproof cable trunking, this protective solution safeguards against long fire exposure even in hazardous areas and explosive atmospheres—providing maximum safety for mission critical applications.

Fuss-Free Installation. Seamless Operations.

To ensure ease of installation, Ashley Edison addresses the concerns of contractors and installers by keeping it simple.

Internal-AVR

ALL TERMINATION POINTS ARE MANUFACTURED FOR EASY ACCESS

We keep the installation process simple and streamlined by allowing sufficient working space for installers. Taking the nut and bolt intrusions into consideration, we ensure that the distance between the uninsulated metal parts, the busbars, and cable sizes are compliant with IEC61439-1 and IEC 61439-2 guidelines.

 

Even in units with larger capacities, all busbar terminals are clearly marked out, and well positioned in line for easy identification of individual input and output terminations. Installation of these terminations are similar to those practised in high voltage transformers.
