Power conditioner types


Do any power conditioners actually store the energy from the outlet/power company and then generate it on demand or do they all filter the current as it is coming through?

Or is it more complicated than that?

If any do store it, are they a different class?

@erik_squires - sounds like you are a fan of my Furman.....good to know. Now if I can only get a silver face plate for it......any ideas?

Capacitors have values, the unit of capacitance being the Henry. Most of our caps are measured in mH, milli-Henry’s, because it is a hard way to store energy. 

Uh....No. The unit of capacitance is the farad. The unit of inductance is the Henry.

What you are referring to is called a "power supply smoothing capacitor" and every amplifier already has one (or more) in it :-)  You do not need a power conditioner for that function :-)

Good correction:
Farads, millifarads, microfarads. 
A Farad is quite a large amount of energy storage capacity. For example, my current power amp has 108,000 uF, or 108 Farads. A lot of storage and smoothing for a D.C. power supply.

I think this is called a battery. but then you would also need an inverter to transform the DC current back into AC if you want to plug-in big stuff like amplifiers. better yet, you can run some components like dacs directly from the DC current and completely isolate them from the grid without too much battery power. Anything that runs off a wall wart take power supply is a candidate for a DC power from the battery.

A can of silver spray paint should do the job. :-)
