Stellar PowerPlant 3

<strong>Our most affordable AC regenerator, the P3 protects, purifies, and powers sources, as well as small to medium sized systems.</strong>

The Stellar Power Plant 3 stands on the shoulders of giants.

Built as an evolution from our renowned P12, P15, and P20 the P3 is our most affordable regenerator – perfect for powering sources and small to medium systems.

Power Plants generate sine-wave-perfect, regulated, high current AC power from your home’s AC. Problems on your power line such as low voltage, distorted waveforms, sagging power, and noise are eliminated and the power quality enhanced.

The Stellar P3 PowerPlant provides greatly improved performance and safety from just plugging into the wall socket, along with far better dynamics, more authoritative bass, and a much bigger, more open soundstage than any passive power conditioner on the market.
$2,999.00

Design

The Stellar P3 PowerPlant features an ultra-low impedance analog AC power amplifier, pure DSD FPGA based analog sine wave regenerator, and low distortion high-dynamic-peak-capable outputs found only in PS Audio PowerPlants. Designed with elegant simplicity in mind, the P3 is a plug and play device that will provide you with perfect power and worry free protection from surges, spikes, and ugly power without any fuss. Regulate, remove distortion, and get better performance.

Application

The P3 is the perfect companion for improving system performance and ensuring a safe environment for you Hi-Fi system. Providing 300 watts of continuous power output and peaks of 1000 watts, the P3 is just right for source gear or an entire systems running small to medium class AB amps or larger high-efficiency Class D amps like the Stellar M700 monoblocks. The P3 will bring forth all that's possible from your HiFi system, ensuring you get the same great performance every time you listen.

Overview

The Stellar P3 PowerPlant takes your incoming AC power and converts it to DC, similar to what comes out of a battery, and then, with patented PS Audio technology, regenerates and produces new sine-wave-perfect, regulated, high-current AC power. In the process of regeneration, any problems commonly found on your power line, such as low voltage, distorted waveforms, sagging power, flat-topping, and noise are eliminated. The input voltage to the PowerPlant is fully protected by state-of-the-art clamping devices and the output is fully regulated so even large voltage swings that would normally damage connected equipment are made safe by either clamping or regulating. With your system powered directly from the ouput of the Stellar P3, dynamics and openness are breathtaking. New voices, new harmonics, and a renewed sense of musicality are yours the moment the P3 starts up.This is one of the most important pieces of audio equipment you can own, building a firm and reliable foundation for your system that will serve you for years to come. Not suited for class A or A/B amplification in 220V models.

Output

The P3 takes in your home's noisy, distorted, and unregulated AC and outputs pure and perfect power that dramatically enhances sound quality. It does this by rebuilding the AC, lowering output impedance, and regulating the voltage. Low output impedance is critical to maintaining a dynamic presentation. Powering equipment through a passive power conditioner only worsens the problem and should be avoided. The Power Plant, on the other hand, has such low output impedance (0.008Ω vs. typical 0.4Ω) that even the hungriest of amplifiers won’t be starved for clean AC power. When your amp is asked to produce loud orchestral levels, you want to make sure it has all the power it needs and only a Power Plant provides a constant output regardless of the dynamic demands of equipment or your neighbors. Power Plants also generate new waveforms that enhance the capabilities of your equipment. MultiWave extends the peak charging time of the sine wave so connected equipment has more energy storage and less power supply ripple. The results are dramatic: a bigger more musically accurate soundstage than with a simple sine wave.

Protection

An electrical surge, or spiked transient, is an intense, short-duration voltage increase that travels through electrical wiring in our homes. It can severely damage connected equipment. Shielding devices from these potential electrical problems is mandatory if we're to protect our investment and ensure the safety of our homes. These electrical transients are not the only potentially damaging problems faced by our sensitive audio systems. There are also sustained over-voltage conditions that many surge suppression devices will not be able to protect equipment from. Owners who have invested in a Power Plant can rest assured their connected equipment will be safe from any power line event such as over voltage, under voltage, surges, spikes and potentially threatening problems. The input voltage to the Power Plant is fully protected by state-of-the-art clamping devices and the output of the Power Plant is fully regulated so even large voltage swings that would normally damage connected equipment are made safe by either clamping or regulating. In most cases, connected equipment enjoys the protection and performance benefits of fully regulated power, even under extreme circumstances.
