V is for Voltage Regulator

Welcome to a regular feature on the Powertecnique blog. Every Monday we talk you through an A-Z of the terms you hear associated with critical power supplies. In this latest post we’ve reached the letter V. V is for Voltage Regulator.

In the United Kingdom, most electrical equipment is designed to work from a power source operating at 230 volts. This is the standard electrical output you can expect from the national grid, but this is subject to some fluctuation. As a result, many products require protection from this over-voltage or under-voltage and that’s where a Voltage Regulator steps in.

A voltage regulator is a piece of equipment which maintains a steady output voltage and cleans up the power supply to your electrical equipment. They tend to have a range in which they can operate, so very large spikes or sags may not be completely wiped out, but regulators do take care of the day to day changes which occur in your electricity supply.

So why would you want one? Primarily because whether you realise it or not, voltage fluctuations can damage your equipment permanently. Often this damage may not be discovered until it’s too late and prevention is ALWAYS easier than a cure!

The good news is that if you have an online UPS then this regulates the output voltage automatically. One more reason to get a UPS!

Hopefully this has given you a bit more of an idea as to what a voltage regulator is and why you need one (or a UPS!). If there’s a topic you’d like covered in our A-Z why not get in touch via twitter. Our handle is @powertecnique.
