If you are looking for the best power conditioner in the market, you will find these items from several brands. As there are so many options, you may face difficulties in choosing the suitable one for your purpose. All power conditioners are not of the same quality, due to which you should always do proper research before buying one.

What is a Power Conditioner?

A power conditioner is a machine that can offer protection to your sensitive electrical components against fluctuating voltage. It works as a buffer between your gadgets and the power outlet. It is designed to improve the quality of power provided to a PC component. This device is related to a voltage regulator that helps to improve the power quality through transient impulse protection, power factor correction, or noise suppression. It not only regulates voltage fluctuations but also electromagnetic and radio frequency interference.

It helps to offer dynamic power adjustments and remove spikes, surges, noise, sags & frequency irregularities. Thus, it helps to regulate and clean AC power. Spikes, noise, etc., can damage your system or affect the performance of your components. Both users and big corporations use these. IEEE, NEMA, and other standards recognize power conditioning.

These may be electronic or transformer-based. Also, we know it as a line conditioner. It enables you to correct voltage and waveform distortions. Besides, it helps to remove external electrical noise caused by motors, radios, etc. Frequency and electromagnetic interference are some examples of external electrical noises.

What is Power Conditioning? How does Power Conditioner work? 

It works as a buffer between the Power Outlet and the Gadgets connected to it. Previously‌, people used to do power conditioning in industrial, research, and laboratory applications.

Benefits of Power Line Conditioner:

Power line conditioners intakes the power and then modify it based on the requirements of the connected machinery and devices.

 Equipment Protection:

It protects your system against voltage surges via phone lines, electrical lines, Coaxes TV inputs, and LAN connections. Otherwise, your system may fail, or you can face degradation in system performance.

Noise Removal:

It helps to remove noise that comes from radio and TV stations, mobile devices, motors, etc.

Fluctuation Correction:

The machine helps to correct fluctuating voltage and waveform distortions.

Types of Power Conditioners:

Passive-Type Filters:

These are the least expensive type of Conditioner. This Passive-type filter helps to keep high-frequency noise components away with the help of a capacitor. They come with basic noise-reduction capabilities.

Balanced Transformer:

It helps to reduce noise superior to passive inductor-capacitor models. Besides, this tool comes with a balanced isolation transformer that helps balance the AC power feed. It generates less noise and is ideal for audio and video components. Compared to passive-type filters, these cost higher. Besides, these are heavier and bigger also. It provides a limited offer for the damping effect of the balancing transformer.

AC Regenerative Types:

These are bigger and costlier than others. It generates plenty of heat during operation. However, it helps to address the issues that are related to noise in the audio and video spectrum. This type of machine helps to correct waveform distortion, regulate AC voltage, and reduce lower order harmonic noise. The working function of an AC regenerative power conditioner is the same as a power generator. These top-class items use automatic voltage stabilization circuitry along with a microprocessor-controlled variable transformer. Thus, it helps to provide new AC voltage to your entertainment system.

Best Features of Power Conditioner:

The features are as follows:-

Wall Wart Spacing Indicator:

It is one of the significant features you must consider before picking the right one to protect home theaters and other AV equipment. There are a few old AV equipments that are equipped with a big-sized plug. These consume space two times of a single outlet.

Master On/Off Switch:

Ensure that the product you have chosen comes with a master switch. It helps to trim down the electric bill every month. You can power off the components when you don’t need them. Thus, you can save your money and bill.

RFI/EMI Noise Filtration:

It is a bare minimum feature that a conditioner should come with. After filtering away electrical interference, you must get improved sound and visual quality of the home theater system.


All line conditioners must have a warranty and insurance policy. Ensure that you have gone through the warranty terms and conditions before buying the right one.

How much do power conditioning devices cost?

These cost from $80 to up to $3,000. The price of these machines depends on the type, options, and quality. A few of these are available as solo, whereas others are available with point-of-use surge protection devices.

Why do you need to purchase a Power Conditioner for your Home Studio?

If you want to protect the gear in the home recording studio, you just need a surge protector. This machine doesn’t allow electrical surges to fry your component. There are a lot of power strip models available in the market. But you should know why you will need it.

Benefits of Power Conditioner:

We have given here the benefits that you will get from it are not from a traditional power strip.

  1. Electrical Noise Reduction:

Multiple devices are designed especially for recording studios. You can identify this while you find them available as rackmount units. These also feature a cancel-out noise that is made by all equipment.

Every piece of equipment creates noise, and these filters are used to reduce those noises. Besides, these help eliminate noise interference caused by many different gears of various types. Whether you have plugged multiple gear pieces into the same electrical circuit except using any power strip, then you can hear the interference in your recordings. You can reduce noise using a power conditioner when you cannot eliminate it.

  1. More Effective Surge Protection:

The devices provide much better surge protection compared to intensive power strips. It is another benefit that you can get from a power conditioner. Usually, a strip is designed to prevent surges. However, the less expensive models can only stop smaller surges, whereas big surges can pass through to the equipment.

We already discuss that they vary in size and functions according to their individual use. Some conditioners focus on voltage regulation whereas others protect against the power quality problems. They are rated from V-A (Voltage Amperes) to kV-A (kilovolt Amperes). The impedance will be Zero at all frequencies. The power output will follow sine wave with the amplitude and frequency according system standard specification and the respective national standards.


  • It regulates the variation in the Peak and RMS voltage. It regulates RMS in both Swell and Dip.
  • The Repetitive variation in RMS voltage between 91 to 110% can produce flicker in the lighting equipments that can be rectified.
  • It can regulate the spikes, impulses or surges caused by inductive loads or lightening.
  • It can modify and regulate Under-voltage or Brownout.
  • Regulates Overvoltage caused due to voltage raise.
  • Controls Frequency variations
  • Maintain the harmonics and
  •  Maintain non-zero low frequency impedance when load draws more power or in the voltage drops.
  • And maintain non-zero high frequency impedance when load demands more amount of current, dips and spikes.

The cost of such devices determines how adequate the surge protection will be. It is because less expensive models don’t allow any surges to pass through to your equipment. However, a few conditioners are there that can get damaged in operation. In this case, you should replace the device or repair it. Don’t worry, as equipment will remain safe hence. More expensive models are capable of handling any type of surge. These help to offer protection to your equipment.
