Speaking of voltage regulation, any difference between this and this, other than $1,400? It seems 15A should mostly be enough for digital front end, if not all front end components.
Probably fine. Loads are constant therein not fluctuating like with a power amp playing high dynamic music.
Worth noting. When dealing with the available power from a wall outlet the amount of power available is not necessarily limited to the handle rating of the branch circuit breaker.
Using a 15A circuit, #14 gauge wire, for example... Most people seem to think the breaker will trip when it senses 15 amps of current passing through it. That is a false assumption. UL / NEMA states the breaker must trip at a sustained current of 20.25A, (135% at less than one hour). (15A x 135% = 20.25 amps.) At 30 amperes (200 percent of wire rating) in less than 120 seconds. (15A x 200% = 30 amps).
With quick fluctuating loads, at say 40 amps, the breaker may never trip at all if the load is only for a few hours or so.
So the branch circuit breaker will continue to pass the connected load current well above 15 amps, 1800W for a short sustained duration or quick short fluctuations of current draw. Does VD, Voltage Drop, increase if the branch circuit wiring is #14 gauge and the connected load is over 15 amp? Yes, but how much VD depends on the length of the #14 gauge wire X 2. If the branch circuit wire is #12 gauge the VD is less. #10 gauge even less.
I guess the point I am trying to make is, how well will a 15 amp, 1800W, rated power conditioner available power hold up to the availability power at the wall outlet branch circuit wiring fed from the electrical panel. (Electrical panel... A whole lot of available power.) The wall outlet will delivery well beyond 1800 watts for short intervals of current draw in time. What is the power head room, Service Factor, for short durations of overloading the power conditioner? Maybe 10%? 20%? Maybe 30%? I doubt it.
