13.8VDC input run it through an inverter

Any UPS that is big enough to handle the load of a
repeater is usually powered by 24 volts or more 
(many 12 volt batteries in series).

The one I just listed uses an internal DC voltage 
of 48 volts, with all 4 33AH batteries in series.

I agree with you though, the more times you convert
voltage from one level to another decreases efficiency.
At one of our club sites, we have a bank of 6 2 volt
500AH cells in series, being charged by a commercial
Staticon unit. The batteries only have to last about
2 minutes, as there is a HUGE generator that powers
everything at the site. Lucky I guess :)

My machines all run 12 volts  when I loose 120Vac  the only thing I 
loose is the  power amp so the machine goes from 180 watts down to 30 
watts the UPS backup is for the Computer in the shack. when that dies   
Ohh well  no big loss the backup Generator should be running
 before that happens... back up to full power...

RE: [Repeater-Builder] Powering the Repeater With Marine Batteries

2005-01-23 Thread Shanon KA8SPW

Hello all,

  I know Matthew has met his needs but I thought I would share the following
with the group.

  Just last year there was a series of articles in QST on running an
Advanced Glass Mat (AGM) battery as a station backup.  Another ham and I
researched the project for some time and decided to use the IOTA DLS
charger/power supply for our RACES/ARES stations.  It is a switch mode and
we added the optional computer module to provide triple mode.  You can pick
a supply that meets your current requirement, he used 45 amp and I used the
55.  These units charge the battery and supply current to the load at the
same time, when power fails the battery is by itself.  The supply does not
be run through a relay.

  We were concerned that there would be RF noise coming out of the supply as
the last article in QST found in some of the units they tested.  We found a
dealer, Mastertech, who sent us a unit with a offer of a full refund if it
produced any noise on our HF rigs.  The unit was perfect.  I could only pick
up noise is I put the pickup loop into the opening on the side of the supply
where the terminals came out while watching the spectrum analyzer.  Turns
out Mastertech has been to many ham swaps selling their supplies.

  We use the IOTA and a Optima yellow top AGM battery as a station supply.
DO NOT USE THE RED TOP!!  We use a MAXI fuse between the supply and the
battery and a MAXI fuse between the load and the buss.  We also added shunts
and LCD digital meters (that run off a 9 volt battery on a momentary switch)
to monitor both current from the supply and in/out of the buss.  Plus a LCD
digital volt meter to monitor system voltage.

  We learned of a supplier for the MAXI fuse holders, Waytek, that also has
tons of other 12 volt relays and fuse blocks.  Check them out on the web.
Very fast service and the best prices by far.  I used some of their relays
and connectors for my alarm system in my van.  You will want their catalog
if you do any kind of electrical work, car or home.

  DO NOT USE A CHEEP BATTERY CHARGER TO CHARGE A AGM BATTERY!!!  It will
kill the battery.  Charging an AGM over 15.? volts will destroy it.  By the
way, FUSE EVERYTHING!!

Power Supply/Charger = http://www.iotaengineering.com/  Iota Engineering

Batteries = http://www.optimabatteries.com  Optima Batteries - use yellow or
blue top

IOTA supplier = http://www.mastertech-inc.com  Mastertech Inc. - Westly
Miller 1-800-848-0558

Fuse and relay supplier = http://waytekwire.com  Waytek Inc.

Shunts and digital meters =  https://www.allelectronics.com/  All
Electronics

  The AGM batteries can be bought at any chain auto parts store or even from
Cabala's.  Our systems work great.  No relays or switches to change over the
12v, works fine all by itself.  Has taken us through several power outages
already.

The below sites mentioned earlier on this list should also be FULLY read by
anyone wanting to use batteries.

this batt is a AGM .. type

and yes every one should read this

   The method I have prefered over the years is the Motorola Micor

  battery.
 
   The radio site near here uses that power supply to run both
  repeaters and charge the battery as well.
 
   Just my opinion.  I have the one power supply that is in service
  and three more for spare parts.
 
   A number of years ago, had one site with three 100 watt Micor
  repeaters ... each repeater had one of the power supplies.  The
  output of the three power supplies were paralleled and charged two
  Size 8D 'cat batteries.'
 
   One day I went to the site on a maintenance schedule and found one
  side of the radio systems primary power circuit breaker had failed.
  That caused one of the above power supplies to power all three 100
  watt repeaters - for how long?  I didn't know.  Seems two of the
  repeaters were plugged into the failed side of the power line / the
  remaining repeater was on the other side of the power line.
 
   BTW, two of the repeaters were public safety / the power supply
  that was supplying all the power was on the amateur radio repeater.

Well call this luck of the draw.  I just had donated three 86 amp hour
batteries and the charger that came out of a telephone communications tower.
Probably will go pick them up next week.  So till then, guess I don't get to

Thanks for the input from everyone who replied.

I agree!  One only know how much damage could have been created once the
power supply died.  I don't even know if it sent any power backwards, but no
damage to the equipment.  The donator of the batteries is a commercial
broadcast technician as is his father, and has offered his knowledge in
helping with the repeater.  So this is all a good thing.

2005-01-22 Thread Ronny Julian


I think you are talking about Optima batteries.  Yea I've got one in my
Minivan :)  It's the main battery and has been working great for quite
awile.  3 year free replacement.  I have the Red top battery but all the
young bucks say the yellow lasts longer.  I didn't see much difference.
http://www.optimabatteries.com/publish/optima/americas0/en/config/home.html

I'm adding a second one thats going to live in the rear part of the van.
You can mount these upside down in the passenger seat if you so desire.  No
venting issues (they say)  Real nice thing if you have a GM (side post)
battery,  It gives you that extra set of top posts to wire radios to in a
separate set of circuits.  I'm running a 4 guage to the rear of the van and
using a expansion block to split it off to several fused circuits for other
radios.  Also fused at the battery.

and the price is not bad ..  we paid $100 each for them  and verry

and we also have them on the outside of the UPS .. thay wont fint

You should at least check the option BB on the Astron. The backup
option gives 13.8V current limited at about 3A. We just replaced
four deep cycle batteries in parallel after about seven years of service

Well the battery and power supply problem
was rectified by a ham that lives about 30 miles from the repeater. He
recently began using the repeater. He over heard me talking to another
ham telling him what happened to the power supply, and jumped in and donated
three large capacity lead-acid batteries that came out of a telephone tower
with the power supply to charge them. He is going to and set them up here
in a few days. Luck would have it, that his dad and him are both
commercial broadcast technicians and is offering his services on the repeater
technical end. I do appreciate all the support regarding this.

  The method I have prefered over the years is the Motorola Micor 
 repeater TPN1105A/TPN1106A Power Supples that also charge the 
 battery. 

  The radio site near here uses that power supply to run both 
 repeaters and charge the battery as well.  

  Just my opinion.  I have the one power supply that is in service 
 and three more for spare parts.  


  A number of years ago, had one site with three 100 watt Micor 
 repeaters ... each repeater had one of the power supplies.  The 
 output of the three power supplies were paralleled and charged two 
 Size 8D 'cat batteries.' 

  One day I went to the site on a maintenance schedule and found one 
 side of the radio systems primary power circuit breaker had failed.  
 That caused one of the above power supplies to power all three 100 
 watt repeaters - for how long?  I didn't know.  Seems two of the 
 repeaters were plugged into the failed side of the power line / the 
 remaining repeater was on the other side of the power line. 

  BTW, two of the repeaters were public safety / the power supply 
 that was supplying all the power was on the amateur radio repeater.

Got one to spare...Hi HiI don't have a problem running the batteries,
it's keeping them charged at a rate that they can handle.  We don't often
loose power here, but there are those times.  I plan to buy a generator, but
still like the idea of the batteries.  I've had other's say they have just
used a regular car battery charger with no problems.  I'm just thinking
there is no regulation or isolation at all on them.  What is the thought on
just using a battery charger.

Re: [Repeater-Builder] Powering the Repeater With Marine Batteries

2005-01-21 Thread russ

Hey every one,
Here is something neat. One of the repeater groups around here took a
computer type UPS and took out the lead acid battery and installed two deep
cycle marine batteries in parallel and it seems to work fine for them. The
repeater has no hum or buzz. Mite be some thing to look into. It sure would
be down and dirty cheap.
Very best of 73,
Russ, W3CH

Subject: [Repeater-Builder] Powering the Repeater With Marine Batteries




 Last night my power supply took a dump!  Good thing for backups.
 Anyways, what I am wanting to do is put 3 marine batteries together
 to run the power for the repeater with a charger to charge the
 batteries.  If I use a 12 Volt Car charger, do I risk the chance of
 noise, or would the batteries filter that.  What would be a good
 source to charge these batteries?  The power supply that will be
 taking the place of the worthless Pyramid supply will be an Astron
 52 Amp Rack Mount Supply.  I have heard in the past that batteries
 have been charged with these power supplies, but not sure if this if
 true or not.  Any ideas?  Thanks.

 Mathew
