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

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. http://www.powerfactorinc.com/Batteries/dg12-32jh.htm this batt is a AGM .. type and yes every one should read this http://www.batterystuff.com/tutorial_battery.html 73 and good luck, Shanon KA8SPW, Garden City, Michigan *** -Original Message- From: w9mwq [mailto: Sent: Friday, January 21, 2005 12:12 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Powering the Repeater With Marine Batteries Last night my power supply took a dump!

RE: [Repeater-Builder] Powering the Repeater With Marine Batteries
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 use my amateur station as I robbed the power supply. Thanks for the input from everyone who replied.

Re: [Repeater-Builder] Powering the Repeater With Marine Batteries
And also note that marine grade batteries wont last very long in standby duty,a little better than a car battery but not much. Its worth the extra money to buy gel cell type batteries designed for that type of duty.They are also totally sealed which may be required if used in your home or at a big tower site.

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

Just to add to Russ, W3CH. The local club in NJ that did this did NOT install the battery's in the UPS. That was not made real clear. They sit next to the APC brand UPS in two Sears battery boxes. This has been working on there repeater for well over a year. Russ is correct it is very cost effective back up power. 73, Dean Westbrook, EE,PE. Cook Towers, INC. Yahoo!

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

Its worth the extra money to buy gel cell type batteries designed for that type of duty.They are also totally sealed which may be required if used in your home or at a big tower site. Ever see a hydrogen explosion rip apart a battery? Also,pay attention to the recommended float voltages of the manufacturer,also a good idea to give them an equalizing charge monthly.

Re: [Repeater-Builder] Powering the Repeater With Marine Batteries
We also use the same idea here ... we use 2 batts from the scotters .. thay are sealed lead acids . work great !! and thay can really be drawn down if needed ( that's what thay where made to do) and the price is not bad .. we paid $100 each for them and verry will worth it and we also have them on the outside of the UPS .. thay wont fint inside :) if any one wants a model # I can provide or just go down to your local batt store .. NO not sears or the same .. but a true batt store and look around Rick On 21 Jan 2005 at 19:16, [EMAIL PROTECTED] wrote: Just to add to Russ, W3CH.

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

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

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