Re: [WISPA] Another Ubiquity question
Now in the 7th day of testing on the LM317 DC voltage regulator for the NSM5 and it's all good news. I regulated the voltage up to about 20v average and the LM317 doesn't even get warm. With so little heat dissipation there is likely to be very little loss also. This looks like a solution - - - *Olufemi Adalemo* M: +234-803-5610040 M: +234-809-8610040 f...@adalemo.com On Mon, Oct 22, 2012 at 11:58 AM, Olufemi Adalemo adal...@gmail.com wrote: Yes I was warned about the head dissipation.

Re: [WISPA] Another Ubiquity question
That depends on wire size. That distance is not going to be ethernet so I will assume #12 AWG, 400ft, copper wire, etc. You should be seeing a 5.6% drop under a 1amp load or about 25v under load.

Will they fail ? maybe If you burn them up. you are on your own.. ? or at least at UBNT's discretion, since you are voiding the warranty, by operating our of Specs. Will it shorten the life of the Radio ? maybe... Will is just work fine ? maybe. This reminds me of the discussions on the CPU Over-Clockers Forum..

Re: [WISPA] Another Ubiquity question
I just put up 2 new solar panels yesterday to replace 2 that were now to small of wattage to cover the expanded load at the tower. Panels with no load were putting out 35 vdc, at the batteries with load I was seeing 28 vdc. I use the tycon voltage regulator to maintain 24 vdc to the radios. Added cost, yes, but this is a remote site with important backhaul and I don’t need to burn a radio out. I was also taking 12 vdc from one of the batteries, but found it would drain it in about 2 weeks... the batteries do not charge evenly, maybe one of our EE members can explain this. 4 12 vdc batteries, 2 in series, then the 2 sets in parallel., most equipment is taken from the 24 vdc, one switch takes power from the 12 vdc.

Re: [WISPA] Another Ubiquity question
Because you are pulling more energy from a given cell. Current typically flows in one direction at a time. If you are pulling current off of the whole system all the time, AND pulling more from part of the system, then there is never a chance for the system to come back to equilibrium. Think of it like having four tanks of water each connected with siphon hoses. If you have two hoses pulling water from one of the tanks, it will drain faster than the other three tanks with only one hose. Your charger doesn't realize that one cell is being drained faster as it is only looking at total voltage across the system.

Re: [WISPA] Another Ubiquity question
The diode thing works fine IF you use the right diodes. For running a UBNT 24V device off a 24V battery floating on a charger, try 4x 1n4001 dioeds in series. will drop about 3V and carry 1A Works fine for me. That set of diodes will only carry one UBNT radio. Need a separate set for each radio. On 10/15/2012 4:38 PM, Josh Luthman wrote: I tried that method. Diode got hotter than hell.

Re: [WISPA] Another Ubiquity question
The problem isn't that you'll completely discharge the part of the bank you're pulling 12v off of, but rather if you discharge the bank unevenly and charge the entire bank in series then you're either overcharging the part you're not pulling 12v off of in order to properly charge the part you are pulling 12v off of -or- you're going to undercharge the part where you are pulling off 12v if you properly charge the part of the bank where you are aren't pulling 12v off. There's just no way around that. Swapping which part of the bank you're using to pull off the 12v will help but you'll want to swap much more frequently thank bi-anullay. You'll want to swap at least once a month. If you only need 8W of power, then if you use a 24v to 12v regulator that's 90% efficient or better the losses will be negligible.

My two cents: If you discharge part of your battery bank unevenly (pull off just half of your 24v bank to get 12v for some loads) you will have trouble with part of the bank getting over charged and part of the bank not getting charged enough. If you were charging the bank with an AC charger that charges each battery individually according to it's needs that wouldn't be a problem. But if you're charging the entire bank with a single device that charges the entire string in series like a 24v solar charger that is not a good way to go. You'd be better off with a 24v to 12v regulator.

Re: [WISPA] Another Ubiquity question
I have a PS2 wired to the 12 starting battery of a generator which starts and stops a few times a day with no issues. The PS2 doesn't even reset when the gen starts and the battery pulls down to around 8~9 volts while the starter is cranking. When the gen runs the batt voltage goes to ~14.6.

Re: [WISPA] Another Ubiquity question
Thanks Greg, I can see how putting load on just one part of the battery bank could cause issues but this load is quite small compared to the total battery capacity. I will be putting only 8w on two 150Ah 12v batteries (3600Wh total capacity). It would take 400 hours to deplete the battery bank with this load only, do you still think this will be a problem? If this will be a problem I could have the load moved from one bank to the other at a scheduled maintenance visit say twice a year. I really appreciate the advice.

If you were charging the bank with an AC charger that charges each battery individually according to it's needs that wouldn't be a problem. But if you're charging the entire bank with a single device that charges the entire string in series like a 24v solar charger that is not a good way to go.

Re: [WISPA] Another Ubiquity question
What voltage were the batteries spitting out? They charge at 27v but without a charger put out much closer to 24v until they begin discharging. If it fried the radio I would first think that it was connected wrong, not that the voltage was too high.
