Does Your Electrical Power Meet Spec?
Probably not. Audiophiles and videophiles alike know a lot about sound and video but not much about the role their own electricity plays in the performance of these systems. After all, most of us just assume the electricity coming into our homes and offices is clean, stable, and free of noise and distortion. As long as it works, we don’t actually spend much time thinking about it. However, the Power Grid is 100 years old now and the system is showing signs of its age now.
Here’s the problem: The electricity coming into our homes and businesses is noisy, distorted, and unstable. Non-linear loads from switching power supplies (computers, portables) generate high levels of distortion in our homes. The video clip below demonstrates just how bad the mains power really is in London and is symbolic of what most people experience worldwide everyday.
The specifications for the electricity we use in our homes and businesses are meant to serve the greatest number of consumers, or as the Public Utility Commission calls it, “the greater good.” It might be fine for running our refrigerators, toasters, air conditioning, lighting, and computers, however, recent tests prove without a doubt that the utility-supplied electricity is not close to being good enough to operate today’s high performance audio video systems.
The waveform above shows a flat-topped, ragged sine wave that causes high-end electronics problems. This waveform requires a double-conversion on-site AC regenerator to rebuild a new sine wave. It’s caused by the Utility turning on Power Factor Correction (PFC) capacitors at a sub-station that are a required part of the electrical distribution system. The waveform that it causes is allowed by the Public Utility Commission (PUC) as the “greater good” for the most people and in their opinion any device that is vulnerable to it would require a customer provided solution. The capacitors are causing the transients at times of peak demand.
The effectiveness of using the right power conditioner in correcting the power quality problems associated with Utility delivered electricity can be easily demonstrated. When electricity with distortion, noise, voltage instabilities, sags, power outages and even unstable frequency is used as the source for a PurePower Off-Grid Power Supply, the result is dramatic. The output of the regenerator is pure power with a new, clean, stable voltage sine wave.
The Solution: PurePower converts the inbound AC from the local electricity provider to DC, removing all the noise and distortion in the process, before creating a brand new AC voltage sine wave, augmented by its own internal battery system. The battery system provides total isolation from the local power grid, so that the very common voltage sags, surges, and transients can’t affect the AVsystem, even in a blackout. It even removes that nasty hum in your amps transformer.
It doesn’t matter how distorted the input – the output is always the same. It is a complete solution.
If you own a high performance system, and suspect your electricity is degraded, PurePower has the solution you have been searching for.
