Re: [WISPA] Proper 24V battery float voltage

2011-05-27 Thread Scott Parsons

Basically 27.2V to 27.6V at 25C
-30mV/degree C temperature factor
Colder temperature require higher float voltage and higher temps require
lower float voltages.

AGM and GEL would be the same. Wet Lead Acid batteries are different
charging specs.

Hope this helps,
Regards,

It depends on the temperature, it's been a while since I researched it, but
if I remember correctly I decided the best compromise around here would be
~27.5v. you may want it a little higher or lower depending on your climate.

I would check the battery manufacturer's website, at least one that I
checked had a chart that showed the proper float voltage at various
temperatures.

Subject: [WISPA] Proper 24V battery float voltage

Hi,

Would someone mind sharing their experience/suggestion on the proper float
voltage for a 24V battery bank (2x 12V 44Ah AGM batteries)?

I'm using the MeanWell DRP-240-24 along with a DR-UPS40.  It's not a three
phase charger, but just limits the charging current to 2A.  The voltage is
adjustable at the source, and will ultimately determine my charge/float
voltage.  Based on my research, the highest voltage I should use is 13.8x2 =
27.6 to avoid boiling the batteries but still achieving a maximum charge.  I
was about to move on until I found another source suggesting that the ideal
float voltage for telecom UPS batteries was 13.2x2 = 26.4.

Thoughts?

Thanks,

Re: [WISPA] Solar

2011-03-01 Thread Scott Parsons

http://www.streakwave.com/Itemdesc.asp?ic=RPST1224-100-60&eq=&Tp=

This might work perfect for you. Has dual power. Power from POE or solar.
Will give a couple days backup or run from solar independently.

http://www.streakwave.com/Itemdesc.asp?ic=RPPL2424-18-30&eq=&Tp=

This one will only do 8W continuous so it won't be able to power your
equipment continuously by solar but it takes POE power and the solar panel
will extend the battery backup.

POE Injectors

I'm looking for some poe injectors, 2.1mm power feed, a power light would be
preferred but not absolutely necessary, surge protection a bonus

I do require shielded ethernet ports that are both connected (the shields)
to each other or to power ground as well.

I have used the little white triangle looking ones with the green lights but
everybody shows them out of stock.

Anyone have any idea who has them or a product you recommend. They are going
into a box I am making to feed a bunch or radios 24v

Re: [WISPA] POE Switch

2010-08-12 Thread Scott Parsons

Hello Paolo,

The 8 port non compliant switch should be available in September.
It has 7 POE ports and 1 uplink port.

It comes with DIN rail adapters for DIN rail mounting. The switches come
with the green DIN rail adapters.


It won't have an way to manage the switch remotely. We are working to add
that functionality to our switches but it is a long project.

also the temperature range is not good for industrial environment.

The switch range is -10C,70C while the midspan is 0,40C

Yes double input would be appreciated

Also a web/terminal (and SMNP?) to see what is happening would be maybe
more interesting than the led on the device itself.

About 1U, I would prefer to have the possibility to have half size (1/2
19") in a frame in order to have multiple things in the 1U slice.

If somebody is in touch with them... ;)

Re: [WISPA] Pole-mounted base stations

2010-07-28 Thread Scott Parsons

The small wind turbines perform best if you can get them to the top.

Air turbulence near the ground causes the turbine output to drop but get up
40-60 feet and the wind stream is steadier and the turbine more consistent.

Yes, that's exactly the kind of thing I had in mind.  Especially since the
non-metallic blades only have a 3' diameter.  Stick a good deep discharge
battery in a box with the charge controller and it should be able to power a
nice Routerboard arrangement, maybe with some Ethernet radios on the side.
The fun will be mounting everything on the pole.  Questions like who gets
the top, the antenna or the windmill?  (Probably the turbine, so it can move
with the wind.)

There is an TP-SW5-NC 5 Port switch with POE voltage from 12V to 48V. You
can't have different voltages on different ports and it isn't a managed
switch.


There is a POE crossover cable to power non standard (moto) with standard

I'm thinking of something that would let a person run a single Ethernet up

Has anyone seen or heard of something like this?  It seems to me to be an
obvious add-on to the radios and a much better way to get more gain than
using the external antenna port on the NS2.  I expect it would be less
expensive than grid and pigtail as well.

Subject: [WISPA] Side Mount to Wooden Utility Pole?

Anyone have any detailed photos or ideas for side mounting to a wooden
utility pole?

We have a site that will only allow side mounting at about 35' AGL on a
wooden utility pole.

I considered building a stand off bracket out of Unistrut and mounting it
directly through the hole with galvanized hardware but it seems a bit
overkill for a single omni.

Thanks!

Re: [WISPA] wind turbine

2010-01-18 Thread Scott Parsons

Those turbine can operate open loop so the controller just disconnects the 
battery from the turbine when the battery is fully charged.
It doesn't hurt the turbine to operate with no load.

Scott

Re: [WISPA] Solar suggestion for ultra low use site?

2010-01-15 Thread Scott Parsons

You have plenty of battery capacity to handle your intermittent load so you
just really have to deal with the standby load. A 10W solar panel would
handle your standby load.
There's a handy calculator at tyconpower.com/learning_center
I would recommend a small 30W solar panel to take care of standby load and
give enough extra capacity to keep the battery bank fully charged.
A 12V 5A controller would handle the charging of the batteries and your
load.
Some prices from beezwaxproducts.com
30W 12V panel $179
12V 5A controller $24.95

Randy,

You don't need a dump load with the Tycon Power Systems turbines. It's just
an option. Some folks like to dump any extra power (after the batteries are
fully charged) off to a heater or other load.

Looking for recommendations on an Outdoor UPS, not concerned about a

Will be fed by AC power, but it can distribute as a single AC or DC

Subject: [WISPA] Need Lightning Arrestor Advice

Hello all,

I am part of a group installing a wireless network in rural Honduras  
for a growing educational system with a chapter of Engineers Without  
Borders (http://ewb-usa.org). We are creating a 7 node wireless  
network spanning a 3 mile radius. Since Honduras is very prone to  
rain storms and lightning strikes, we need to protect our equipment  
from the lightning. We plan on doing the following:

1) Place an arrestor between the radio and the antenna
2) Place an arrestor in the POE injector

Some of the following criteria we are thinking:

Amount of lightning strikes: One or Many
Insertion Loss: Small as possbile
Frequency : 2.4-5.8 GHZ

When searching the internet, I see many many types of lightning  
arrestors given my criteria. Does anyone have any recommendations  
through their experience with lightning arrestors? What do you use?

Thanks!
James

Re: [WISPA] 2.4 ghz 24db grids.

2009-09-17 Thread Scott Parsons

It sounds like your problem might be one of wrong focal length. As I recall
the focal length of the 2.4GHz 24dBi grid was around 16 inches.
If your focal length is off, then any twisting or movement of the wire grid
will have a big effect on the dipole output.

Well this is strange, we've seen it on different model Grids. We saw the

The signal just keeps bouncing 20db from -74 to -94 for example, with an

Re: [WISPA] solar site

2009-08-28 Thread Scott Parsons

IF you need to power 48V equipment from a 12 or 24V battery system take a
look at these 9-36V input 48V output DCDC converters/POE inserters.
It is much more efficient than going the inverter to 120VAC and back to
48VDC route. They supply 30W so should power most 48V equipment.

48VDC equipment is almost always carrier-class and that is where
the expense is.  That isn't quite the same as having a 48VDC power
plant with non carrier-class equipment running on it.

What is really absurd is converting a 12/24/48VDC battery plant to
120VAC to feed a piece of equipment that is going to convert it
back down to 5VDC and 12VDC using a reasonably reliable but highly
inefficient computer type switching power supply.

Cisco and Motorola make some of the most power-inefficient networking
and radio equipment on the market.

No big deal when you are on the grid.  But a real big deal when you
are not.  I guess off-grid sites are just too tiny a portion of their
market to worry about.

2009-08-25 Thread Scott Parsons

Yeah, We don't have the higher capacity yet. For instance our largest panel
is 30W right now and our largest controller is 5A. You could use 3 30W
panels and 2 5A controllers but I wouldn't suggest that because it's too
costly.
Next year will be a different story :-)

Re: [WISPA] TP--UPS-DC-12-9

2009-08-02 Thread Scott Parsons

The power from the controller to the radio board is essentially the battery
power. So with full battery it's about 13.4V and it takes about 26 hours at
3.5W to reach 11.1V. This is a gradual voltage slope so you could set a
warning at 11.5V and you'd have some time to take some action. At 11.1V the
controller turns off the power to the radio in order to keep the battery
from over discharging. If discharge batteries too much it reduces the life
of batteries.

If you want to run at lower battery voltages, you can add one of our
TP-DCDC-1218 or TP-DCDC-1224 DCDC or TP-DCDC-1248 DC to DC Converters
between the battery and the radio board. These units will give regulated 18V
or 24V or 48V DC voltage from inputs as low as 9V. They have a built in POE
inserter and 2 isolated power inputs.

I do not believe the new boards does this do they? The RB230's and I think
as well the RB532 could/would over SNMP report power levels and temps maybe
the newer boards can't report temp but can report power over SNMP. 

If I didn't understand Scott incorrectly the power supplied out from the
controller is stabilized so you will either work or your dead. So to use DC
voltage report you would need a separate board feeding directly of the
battery and as power on the battery start to drain your NMS would have to
trigger on a low voltage problem. 

There is another issue here.. That is that the UPS battery is 12V and most
RB dies or fail when the power goes under 11V. So the window of opportunity
would be very small. Or am I missing something here?

Just bumped into this LPS1000 unit, could replace my Tripplite PDU's 

with it, but it cost 2x+$100 as much as the tripplite PDU's.

Anything else out there like it, 5 POE ports is perfect, but $699 is too 

much.

Need Advise Where to find:

Anyone make such a beast.  I hate the idea of having to use a AC UPS to
convert its battery back to AC just to switch it back to DC at the POE. What
a waste of electricity and it lowers Tower uptime in a power outage.  I know
you could just use a charging unit connected to deep cycle batteries but
what happens when the power goes out and you had no idea and the battery get
down to 8v.  

Surly there is someone out there with one that's <$1k.  Shouldn't be more
than a couple hundred bucks.

Subject: [WISPA] solar planning -- battery and sun calc suggestions?

I have a quad radio node that is 110V AC only, and I'm getting together 
what's needed in order to power it on a solar panel.

Obviously, I'll need an inverter to take from 110V to 48V DC.

Does anyone have any suggestions for batteries?  Someone suggested some 
high capacity 6V ones (like they use on golf carts) and possibly putting 
them in series or parallel (depending on the draw I need).

Also, I hear that there is some sort of sunlight calculator that I'll 
need to use to calculate the battery capacity I'll need to plan for. 
Any suggestions there? (I don't see anything googling)

Any advice here would be greatly appreciated.  (I'm new to planning out 
power requirements.)

Here is a fixed graphic of the National WISP map showing the lower 48
states. I have been getting updates via email on top of what Matt sends from
the directory.  The footprint now covers 567,315 square miles! I'm still
working out the bug that makes the circle radius on the Google Maps smaller
than the 10 mile radius. The land area calculations are done based on the 10
miles.

Help spread the word about this effort to collect data. For those who have
drawn their coverage area in Google Earth, send me that file and I can add
it directly to the map.

Re: [WISPA] Remote Powered Access Pont

2008-11-20 Thread Scott Parsons

Thanks so much for the insight and great information. You just saved me
having to make all those mistakes all over again. I was definitely
undersizing the system and I'd bet most folks would tend to do that, trying
to save costs.

One more question: I read that solar panels will still output on cloudy
days, maybe 75% of sunny day capacity. Have you any experience with this?

Scott

[WISPA] Remote Powered Access Pont

2008-11-19 Thread Scott Parsons

I'm looking into setting up a remote access point/repeater.
Power requirements are 5W. No access to grid power.

I was curious what you guys use for this type of thing?
I figure I need a 30W solar panel, controller, battery and enclosure.
How much should I expect to pay for a setup? 
Is there anything available off the shelf?

Thanks for your help.
