VOLTAGE REGULATOR AND STABILIZERS

Servo Voltage Regulator is a servo motor controlled stabilization system that performs optimum voltage supply using a BuckBoost transformer booster that captures voltage fluctuations from input and regulates current to the correct output. An AC synchronous motor adjusts voltage in clockwise or anticlockwise direction and manages the output voltage with components like control card, dimmer, comparator, transistors, mocs, etc.

VOLTAGE REGULATOR AND STABILIZERS FAQ’s

Here you’ll find answers to some of the more frequently asked questions when looking for a Voltage Stabilizer.

If you have a question that you can’t find the answer to, please let us know by using the Contact Us page.

How much do Voltage Stabilisers Cost?

The cost of a Voltage Stabiliser can vary depending on a variety of factors, of which the two prime ones are – the power rating of the load you wish to protect and the required permissible input voltage window the Stabilizer is expected to operate in whilst still delivering the required output voltage. As a general rule of thumb, on smaller rated applications, Servo Electronic solutions are the most cost-efficient. However, above 80 kVA Static Electronic Stabilizers tend to be more cost advantageous and offer enhanced power protection features with a smaller footprint. To get pricing, please contact us.

What is the difference between a Voltage Stabilizer and Power Conditioner?

In essence both protect against voltage transients, spikes, sags and brownouts, but a Power Conditioner also offers additional protection against Electrical Noise and higher-level defence against transients and spikes. In most cases, a Power Line Conditioner is simply a Voltage Stabiliser with the inclusion of an isolation transformer. When a good earth cannot be provided Common Mode Noise (E to L and E to N) can be a problem. With the inclusion of a shielded isolating transformer in a Power Conditioner, this interference will be suppressed to harmless levels. The output of an AC Power Conditioner is commonly referred to as a Clean supply. As you would expect, a Power Line Conditioner usually is more expensive than a Voltage Stabilizer / Regulator. So, if electrical noise is not an issue on your site, the most cost-efficient solution is typically a Voltage Stabiliser.

What is the best type of Voltage Stabiliser?

Historically, for general commercial and industrial applications, Servo Electronic based Voltage Stabilisers have dominated the market. However, in recent times with advances in microprocessor control, the Static Electronic Stabiliser has really come into its own. Today, as static solutions with no moving parts other than fans for cooling, these types of Stabilizer are leading their field, especially for power applications above 80 kVA. Where the application is genuinely industrial in nature, and the stabilizer is expected to operate in a far more demanding power environment, Magnetic Induction based industrial stabilizers are the most appropriate. However, they come with a heftier price tag!

What Input Voltage Window do I require for a Stabilizer?

In situations where there is a reasonably good mains supply, a Stabiliser offering an input variation swing of ±15% (Our S15 Models) will usually be more than acceptable, but in more remote locations, or countries where the national supply infrastructure is less developed, variations of ±20% or greater may be needed to be accommodated by the Stabiliser. Given that the wider the permissible input voltage window option you select will probably mean the more expensive the stabiliser will be, it is vital to determine before ordering a stabiliser how low, or high, the utility mains supply voltage goes on your site.
