What To Know

  • Electronic devices may appear durable, but their internal components can be damaged by minor power fluctuations; voltage stabilizers prevent this by ensuring a constant voltage supply.
  • Modern flat-screen smart TVs, including LED, OLED, and QLED models, generally do not require a voltage stabilizer due to their wide operating voltage range and built-in SMPS (Switched Mode Power Supply).
  • While not typically necessary in urban areas with stable power, a voltage stabilizer could be beneficial in places with unreliable electricity to safeguard against potential damage to sensitive electronic appliances.

In this article, you’ll find out quickly if your TV requires a voltage stabilizer to guard against power surges and learn how today’s smart TVs handle voltage fluctuations.

Understand the Voltage Stabilizer

Before we shed light on whether your LED TV requires a voltage stabilizer, let’s get to know the current stabilizing device a bit more, for some context.

The electricity supply is not constant. Even though the fluctuations are not as drastic as they used to be earlier, there continue to be variances in their readings.

The oscillations are acceptable within a vacuum. But when they continue at the point of contact with electronic appliances, problems begin.

Luckily, a voltage stabilizer comes in with the rescue.

It lends stability to the power flow and ensures a constant supply of current to appliances so that the low or high-voltage currents don’t damage a voltage variation-sensitive appliance.

Also known as an “automatic voltage regulator,” voltage stabilizers are usually hooked up to air conditioners, television sets, lab machines, medical apparatus, etc.

There are different voltage regulators based on the application type, the load required, the stabilizing function, the feature set, etc. Some are dedicated regulators, and others can be used on any appliance found in a house or facility.

The General Need for Voltage Stabilizers

Most electrical devices are designed to handle a specific input voltage range. They don’t require a constant voltage. Some are, in fact, more tolerant to fluctuating electrical currents than others.

For instance, some equipment could handle voltage fluctuations up to 10 percent more or less than their rated voltage. Others could have a limited tolerance of only up to 5 percent or even less.

Automatic Voltage Stabilizer

Voltage fluctuations happen due to lightning, faulty wiring, electrical faults, etc. And depending on the cause, the voltage dip or surge could be more significant than a device’s voltage tolerance capabilities.

When the voltage numbers are lower than the bare minimum a device needs, the appliance could malfunction, lose efficiency, overheat in the effort to draw more current, etc.

During a high voltage scenario, the device could get permanently damaged, its cables could get fried, etc.

Since there’s no way to guarantee that the voltage changes will remain within an electrical appliance’s particular range, devices are connected to a voltage regulator as a safety measure.

Do You Need a Voltage Stabilizer for TVs?

No, you don’t need a voltage stabilizer for your flat-screen smart TV as they incorporate SMPS (switched mode power supply) and have an operating voltage range wide enough to accommodate almost all types of voltage fluctuations.

But can you have one, just in case? Yes, you can. Even if it’s unnecessary, it will not harm your TV.

The modern-day TV is more intelligent than the CRT TVs of the past, both in general functionality and how it manages its internal components.

Even the CRT TVs didn’t need a voltage regulator, but people hooked them to one anyway because their voltage range wasn’t extensive.

What is SMPS?

Modern LED-LCD and OLED TVs come with SMPS. The electronic power supply comes with native voltage regulation and current-limiting capabilities.

Besides televisions, SMPS are found in DC motor drives, power amplifiers, PCs, and every other electrical device that needs a highly efficient power supply.

SMPS is a vast topic. To learn more about SMPS, watch this video:

Also, as mentioned above, TVs have a broad operating voltage range (110V to 290V). Based on the TV brand and model, the range could vary, but it usually is quite encompassing, like with this Sony TV that has a 110V to 240V range.

The voltage supply seldom falls outside that range. So, your TV is protected that way too.

If you live in a city, a voltage stabilizer for your TV would be a waste of space and money. But if you live in the countryside, a voltage regulator would come in handy, provided your region is notorious for frequent power fluctuations.

But some folks want a regulator device regardless of their home’s power situation.

If you are one of those individuals who would like to have no regrets whatsoever with their TV, or if a stabilizer affords you mental peace when using the TV, go ahead and hook one up to your TV set.

FAQs

Can You Use a UPS Instead of a Voltage Regulator?

No, because a UPS is an entirely different concept. As the full version of its name suggests, a UPS ensures an “uninterrupted power supply.” It doesn’t regulate voltage per se.

If your area is prone to power outages, a UPS will help. But if your region experiences frequent voltage fluctuations, you’ll need an AVR.

With that said, some UPS are hybrids or could serve as voltage stabilizer duties, such as the one below.

Conclusion

To conclude, your smart LED, OLED, or QLED TV doesn’t require a voltage stabilizer. This includes 4K and 8K televisions too.

As stated earlier, TVs have gotten more brilliant both from the outside and inside, and they know how to manage voltage variations better than the TVs released before.

Even the TVs people used back in the day were designed not to be used with a stabilizer. TVs’ power management capabilities have only gotten better since.

With that said, investing in a voltage regulator makes sense if you live in a place with an unreliable, unsteady electricity supply.

The last thing you want is to lose money to a fried TV circuit board just because you didn’t want to spend a little extra on a voltage regulator.

Needless to say, the TV repair cost would be significantly higher than an AVR’s price.
