Re: [WISPA] OT amps and volts

2006-02-04 Thread John Scrivner
Time for some ohm law here guys. The radio you are powering is a load in 
series with a transmission line that has resistance. The ohms of the 
line and the ohms of the load add together to determine the effective 
load for determining the amount of current flow that will be drawn. If 
you already know the number of amps that the radio draws then this gets 
easier to calculate. 24 AWG wire has a resistance of roughly .0302 ohms 
per foot. If you are going 300 foot to the load then you actually have 
300 foot on the positive side and 300 foot on the negative side of the 
load. This yields 600 X .0302 = 18.12 ohms. Now here is where those with 
no electronics background may start to glaze over a bit. We actually 
have two lines for positive and two lines for negative when using two 
pairs of a 24 AWG cat 5 cable. When you have two identical loads in 
parallel the resistance gets cut in half. So the effective resistance of 
the transmission line for 300 feet of Cat 5 24 AWG cable is 9.06 ohms. 
Let's assume the radio being powered has a current draw of 1.2 amps. The 
current flow in a series circuit is the same throughout the circuit so 
the voltage drop across the transmission line would be determined by 
multiplying the amps of current times the ohms of resistance which means 
1.2  amps X 9.06 ohms = 10.872 volts. This means that if a radio needs 
12 volts with 1.2 amps current flow then you would need to supply a 
minimum of about 24 volts at the POE injector. This is because if we 
start with 24 volts and lose 10.872 across the transmission line this 
leaves about 13.128 volts to the radio. If you do not know ohms law then 
you need to do some reading on it. It is easier than I have described 
here once you play with it a bit and you really do use it in your life 
if you do anything at all with electricity. Here is a page I just 
Googled and seems to cover most of the basics:

Re: [WISPA] OT amps and volts

2006-02-04 Thread rcomroe
huh?  I appologize if this was in-jest and I didn't recognize it.

You apply a potential when you connect something (a voltage).  You don't 
apply a current.

Neither voltage nor current kill most things.  There are a few kinds of 
things that are voltage sensitive but not typically found on the input of a 
commercial device.  Power kills most things through direct conversion to 
heat.

There's so many different powering circuits that's is just not possible to 
draw any across the board generalities.  Some things have AC supplies and 
generate DC, some take DC and run through a regulator, some take DC and run 
it into an inverter and then generate their own DC.

Depends on the radio and the powering circuitry.  I know what's in the 
Motorola, and they have an inverter and regenerate their own DC.   If you 
check the specs for some brand radio, if you see a voltage spec with a 
"range" of voltage (say 12v to 24v) its probably running an onboard 
inverter.  These are pretty hardy (they naturally support a wide range of 
applied voltage).

On the other hand, a radio with a voltage spec without a range may only have 
an onboard regulator, and these may be popped by overvoltage.  Simple 
onboard regulators drop the input voltage down to whatever the board wants, 
and the dropped voltage x the radio current is power that is dissipated to 
heat in the regulator.

That is correct. Now if you use a 10 amp supply and only need 2 amps and 
there is a short up top there is a good chance you will burn your cat 5

Re: [WISPA] OT amps and volts

2006-02-04 Thread Haudy Kazemi
A caveat with higher current capacity power supplies (esp. replacing one
kind of battery chemistry with another) is their internal impedence
characteristics may vary, and if the electronics being run assume a certain
impendence, things may go awry.  A specific case is replacing alkaline
batteries in some electronics that depend upon the internal
current-limiting impedence characteristics of alkaline batteries.  In those
electronics, if you try to use NiCads or NiMH batteries, the device
sometimes misfunctions.  (Alkaline batteries have a (much) higher impedence
than NiCads or NiMH batteries, as a result alkalines don't like
high-current loads like digital cameras.  I think certain older film-camera
flashes were among devices that don't repond well to NiCad/NiMH batteries).

As far as using a higher current power supply on an AP, I don't think this
will be a problem.  For long runs it may be necessary to use a higher
voltage (but same or slightly higher current) power supply than the
original in order to overcome the voltage drop over the CAT5 run.  If you
use a power supply that puts out enough voltage but not enough current, the
voltage will drop (to some degree) in order to make up for the current
shortfall (basically you have a brownout).

You can find voltage drop calculators using Google.  Most CAT5 is 24 gauge
wire.  The AP should have an on board voltage regulator to bring the
incoming voltage down to whatever the chipset needs, so being a few volts
(say < 3) above the specified voltage at the end of the 300 foot run likely
is good enough.  If you open the AP and identify the regulator IC (possibly
a three-legged 7805 or 7812), you can then look up its spec sheets for its
acceptable input voltage range.  That said, the closer your input voltage
is to the regulator's output voltage, the cooler the regulator will run and
the happier it will be.

Brian,

  I'm normally a lurker, but maybe your problem is in the 300' run of CAT5.
What kind is it?  You may be getting signal degradation which is causing the
sporadic radio behavior.

Subject: [WISPA] OT amps and volts

I'm a little confused here.  I'm working on a 300 ft run of cat5 and 
have a question.  The radio is acting sparatic.  The power supply has 
already been upped from a 18v to a 24v.  Both 1 amp.  Will it hurt to 
put a 24v 2 amp power supply in?  If I "over do" on amps or volts, what 
blows a radio.  One or both?  I seem to remember being told that a radio 
only takes what amps it needs, so putting a higher amp power supply in 
won't hurt, but if you put too many volts in, that will fry them.  
Please clarify me on this.
