Re: [WISPA] OT amps and volts
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.

Re: [WISPA] OT amps and volts
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 cable up.

Re: [WISPA] OT amps and volts
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. -hk At 09:43 PM 2/4/2006 +0100, you wrote: >Increasing the Voltage beyond the specifications will kill the radio. >Putting a higher power - (current) PSU shouldn't hurt the radio.
