A couple of ideas for in-expensive AC power monitoring 

1. The Canary Method. 
Take a busted radio, any device that can hold an ip address,. respond to pings, 
power it using AC, and use ping monitoring to determine loss of AC Power. 

2 The Mikrotik Method (if your Model of MT has Voltage Monitor). 
If you are using a Mikrotik Router @ Site. Mikrotik Routers can be powered 
using two sources of Power. One on the DC Jack and other on POE (port1). 
By default it will use the power sources with the higher voltage as primary. 
Use this method to power the MT from AC power, as well as DC Power... 
There is a nice script ( 
http://wiki.mikrotik.com/wiki/Monitor_input_voltage_on_RB333/433AH ), that 
allows you to monitor the Voltage, and send email of a change in voltage is 
detected. 

3. The GregSowell Method. 
Create an ethernet loopback plug using a small relay.. 
http://gregsowell.com/?p=2093 

There are other more fancy devices that will give you alters too.. the above 
are the inexpensive versions...

Subject: Re: [WISPA] Portable Alternators? 

Alternatively, run your equipment on DC from an Iota DLS charger, which is 
constantly trickle charging some batteries. When the power goes out, it will 
run a lot longer because you're not converting (like a UPS) from DC coming out 
of your batteries to AC and then converting from AC back to DC again in a POE 
to power the radio. 

Just use DC to DC converters to get the different DC voltages you need to run 
your various equipment. 

Plug your generator into the Iota charger to power it. I bet you'll get clean 
DC out of it. Especially if a battery is plugged in, which I think will help 
smooth out the DC current. I haven't tested it, but we're using DC everywhere. 
Just don't have to use a generator since the battery backup lasts so long. 

I recently had a tower with 6 radios on it, which had two deep cycle marine 
batteries from walmart. Someone somehow left the breaker off after working on 
the site. It ran for 3 days directly off the batteries before going down. We 
now have to monitor each the site is being fed by AC or not. Haven't got around 
to that yet. Maybe some mFi will help with this. Except the single port mFi 
doesn't have ethernet.

2013-05-08 Thread Chris Fabien
I am not sure exactly what you are getting at by using the term alternator.
But a good option is any of the honda or yamaha inverter generators. These
have a DC generator system running a power inverter so the power output is
much more constant. They are also quieter and more fuel efficient because
the engine RPM can slow down to match the load where a normal generator
must run at 3600rpm to get your 60hz power.

I'm looking at inverters as a solution.

We have several generators (they increase throttle based on load and 
generally have very unclean power).

We also have one Sear Alternator that runs at a constant RPM and 
provides some of the cleanest power I've ever seen.  60Hz on the nose @ 
120volts.  As you load it, the voltage slowly goes down, but the Hz 
remains constant.

Now that is a creative solution!

That's exactly the problem -- I believe.  The generators don't have 
enough load with the small pull the WISP equipment has.

 in and the voltage stabilizes, which allows the UPS to kick back on to the 
 line power. It also provides some nice lighting if it's at night.

 I've seen the generators go everywhere from 40Hz to 90Hz.

 Has anyone come across a nice portable alternator (as opposed to a
 generator) that can be taken to tower sites as supplementary power?

You probably want something like this:

Go straight to the battery. Monitor closely. The honda and other model 
inverter generators usually only put out a small amount of amperage via 
DC only.

Especially with those small, cheap 2-cycle, 800-1000W generators, a
200-400W light stabilizes it well.

The other option I've used is to use one of the tripplite online UPS'es
which have a *Very wide* input frequency range.   Because it's online, it
will take the power from the gen, and then clean it up to the right
frequency for the load.

Could you use a cheap 400w power inverter running off of the 12v plug that
most generators have?

Re: [WISPA] Portable Alternators?

2013-05-08 Thread Roger Howard
Alternatively, run your equipment on DC from an Iota DLS charger, which is
constantly trickle charging some batteries. When the power goes out, it
will run a lot longer because you're not converting (like a UPS) from DC
coming out of your batteries to AC  and then converting from AC back to DC
again in a POE to power the radio.

Just use DC to DC converters to get the different DC voltages you need to
run your various equipment.

Plug your generator into the Iota charger to power it. I bet you'll get
clean DC out of it. Especially if a battery is plugged in, which I think
will help smooth out the DC current. I haven't tested it, but we're using
DC everywhere. Just don't have to use a generator since the battery backup
lasts so long.

I recently had a tower with 6 radios on it, which had two deep cycle marine
batteries from walmart. Someone somehow left the breaker off after working
on the site. It ran for 3 days directly off the batteries before going
down. We now have to monitor each the site is being fed by AC or not.
Haven't got around to that yet. Maybe some mFi will help with this. Except
the single port mFi doesn't have ethernet.

Cheers!
