Default OT - Magical HF inverter

HF has a "700w" inverter that runs from a car battery. It is "700 watts
continuous for up to 30 minutes" and has "Auto battery cables and 30 amp
fuse". Is this new physics? Old physics held that 12v at 30a was 360w
and you couldn't have more watts out than watts in. This is even worse
than "Sears horsepower".

I've seen inverters that are supplied with cables that cannot handle the
load, so are fused appropriately.
Maybe the leads are replacable with 100A capable ones, and that's how
it does 700W.

My guess is that the 700W continuous is inflated. Perhaps you should
play it safe and get this model

Your average store-bought UPS has the same deal. In the outside of the box
they are always rated in "VA" rather than in watts. If you bother to read the
fine print, you will find that they assume a ridiculous power factor and your
500 VA UPS is actually a 250 Watt UPS.

^^^^^^^^^^^^^
Vaughn, lets look at this one step at a time. RMS stands for "root mean
square." If you look at the equation for power, it is I^2 R, or E^2/R. For
DC that is very simple, but for AC, it is necessary to use an average figure
for E or I that gives the correct power. The way to get that average is to
square the instantaneous voltage or current at every instant, take an
average of the squared values, and take the square root of the
average--hence: root (meaning square root) mean (same as average) square.

The wattage rating or operating point of an amplifier is already in power
units. It is perfectly OK to talk about "average power," or "peak power,"
but RMS power suggests doing something to the numbers that has already been
done. To square, average, and take the square root again would produce a
figure that has no meaning. That's my gripe.

Agreed that average power is more useful and descriptive than RMS
power. For unvarying power output they're the same. Peak output
is also a useful measure, though. Two amps with identical average
power ratings may differ in the peak power they can deliver without
clipping on transients like rim shots on a snare drum. Average
power rating is determined by the amp's efficiency and ability to
dissipate heat. Peak power would be governed by available supply
voltage and the output devices used. The length of time that it can
deliver peak power without overheating is determined by the thermal
mass of the heatsink.

But if you use a standardised method of measurement (sine wave) the
RMS is the same power dissipation as DC, isn't it? So you are
measuring the ability of the amp to continuously dissipate heat,
basically.

Taking the square of a number that has _as part of its makeup_ a
squaring process of only one constituent of that number is not "doing
something that has already been done" at all.

To be meaningful Watts RMS in audio also need a distortion, bandwith and a
load specification such as:

2500 Watts RMS at 4 Ohms with a THD (total harmonic distortion) of .001%
from 20Hz to 20KHz.

I think this is really a case of technical illiteracy on the part of the
people who market power amplifiers.

What gets called "watts RMS" is actually average (mean) power. To
*calculate* this, they measure RMS voltage and then feed it into the
standard V^2/R power formula. The whole point of using RMS voltage,
instead of average voltage or peak voltage or any other measure is that
it allows you to calculate mean power.

But the actual number quoted is watts, not volts, and it is *mean*
watts, not RMS watts. The name "watts RMS" is simply wrong, even when
the number is right.

RMS watts is well-defined mathematically, but it doesn't have any useful
meaning for measuring an amplifier output.

On the contrary actually, I consider RMS to be the most meaningful

in.

As far audio goes I'd be more interested in THD, peak power/dymanic

I can see your point however once you're away from DC or working
outside narrow specialty fields where it's assumed everybody knows
"Whats Watt" the term "watts" by itself can be mis-leading. If you
say watts RMS everybody (at least in my experience) knows what you're
talking about. For commercial power situations where you can run into
power factor issues "VA" is a better concept. For audio I just buy
the biggest amp I can afford & say the heck with the rest.

So, anytime I set the power output on an AM or FM transmitter the ol'
Bird 43 sez "Watt RMS". Same thing on the HP power meter when I'm
doing micro wave links, except that when measuring at the directional
coupler it generally comes out in "milli-watts RMS". And thats not
even using the BIG Bucks "True RMS" meters they sell. SSB is, of
course, Not to be Talked About Here .

Anytime I set or measure a level on an analog audio line using a test
tone I'm usually looking for a given level of dBM, where 0 dBM is, by
definition, equal to 1 mW, RMS .

I recently designed an oil heater with a non-inductive load (duh). I
calculated, using the resistance of the element and the 115 V RMS
line level, the RMS power disapation in watts which I then cleverly
converted (Convert.EXE- Gotta Luv It!) into calories to figure out how
long it would take to heat up the oil under given conditions. When I
actually tried the thing out I was pretty damn close :0.

In point of fact, I find RMS usefull every day of the week, &
sometimes twice on Sundays .

range & whether or not the dual isolated power supplies were built

Remember - Power = I^2 * X where X is the reactive value of the system
at a specific frequency, not all frequencies.
So really one has to do a sum of I(@20hz)^2 * by Hz
So in this case, the root of the mean square comes closer and closer.

"RMS watts", although mathematically possible to compute, would have
no useful *physical* meaning that I can think of. Usually they are a
misnomer for "true power".


RMS Watts gives the actual power to do work. Assuming the
signal is a sine wave, and assuming (for convenience) the load is a pure
resistor acting as a heater to avoid needing to deal with imaginary
current):

1) If the input power is 120 VAC (that voltage is *also* RMS, BTW.
for 120 VRMS, the peak voltage is 1.414 (sqrt(2)) times the RMS
voltage. So -- with that 120 VAC RMS, you get a peak voltage of
169.68 V

2) Now -- let's assume that the resistor is 100 Ohms, so at that
peak voltage, it would be dissipating 287.91 Watts.

3) However, it is doing so only for a tiny part of the whole
cycle. At other points, it has voltages much less than that
peak, and even less than the 120 V which the RMS value has.

4) So -- if you actually measure the heat output, and do the
necessary math, you will find that the actual average heat out
of it is the same as though it had 120 VDC applied.

5) So -- RMS is a measurement of how much work you can get out of
the signal, whatever it is doing. (In an audio system, that
task happens to be moving air in specific patterns.) How much
you can actually get out is also a function of the efficiency of
the speakers, usually with the higher quality speakers being
less efficient -- more of the power is going to controlling
cone overshoot and other forms of mechanical distortion.

As far audio goes I'd be more interested in THD, peak power/dymanic
range & whether or not the dual isolated power supplies were built
using oxygen free silver buss bars .


The "peak" power used in audio rating is not even that used in
my explanation above, which at least has a basis in physics. Instead,
it is what power you can get out of the amplifier for an instant before
the power supply capacitors discharge to a lower voltage. So -- your
peak power gives you an idea what a single castanet clack can produce
(hopefully without distortion) -- but no promise that a rapid series of
them will produce the same sound.

The RMS power, instead, gives you a *real* measurement of how much
power it can produce for a long sustained note. It is *defined* for a
steady-state output. It can even give you an idea whether you can run a
machine tool motor from the output.

Any attempt to run a 100 W light bulb from an amplifier rated at
100W Peak will burn out the amplifier in fairly short order. An
amplifier rated in RMS Watts will do the job -- assuming that it can
produce enough output voltage (not a guarantee even with your preferred
peak Watts).

Guess you don't remember the amplifiers that said 100 watts!
100/2 - 50/channel then that is peak to peak value - /2 (again) multiply by 0.7
and you find out the speakers you are using consume 10 watts before
sound is heard from the big cones - take it back doesn't work!

Peak to peak numbers and peak values were rampant. Finally standards were done.
Had to be RMS voltage * RMS current. E*I.

Liken it to the Horse power of power tools - one horse is a pony another
is a Morgan.

RMS is the effective heating power into a pure resistance = EMF voltage for same heating power.

Right. And assuming that the load is resistive (it is when testing
amplifiers, but not when driving speakers), then RMS voltage * RMS
current gives you *mean* power, not RMS power.

RMS is the effective heating power into a pure resistance = EMF voltage
for same heating power.


Mean power is heating power. If you have a meter that reads power,
you just average the output. It's only when you're calculating power
from voltage and/or current that you need to use RMS measurements.

Now I have to tell you how I know about the three fuses. Bought the unit at a swap meet for $5. Being dead, I opened it
up to find the three fuses blown. Someone had wired it up backwards. Turns out there are three separate inverter
circuits. Wired in parallel on the output side. The inputs also have protection diodes, all three of which were cracked
in half. Replaced fuses, diodes and repaired a burnt trace. I now have 700 mobile watts available....Paul

Yes I did. Uncharacteristicly I find myself commentless, that is to
say unable to come up with any statement that would even come close to
expressing 1% of what should be said about the subject.

Too bad, I'm sure that if I could it'uld be a real Zinger .

I loved the magazine reviews. My subscription to those magazines, if
they exist, would require a lot of thought.

Makes Monster Cable look like god's truth personified.

Personaly, I'm a firm believer in the superior acoustic properties of
Zip Cord .

As for the other sentiment, I really don't believe the concept of
"thought" in any way belongs in a sentence discussing a subscription
to any of those rags .
