Re: [WISPA] powering finicky mikrotiks on 24v solar - $2.75 solution
I came up with a solution for this problem for now. I use West Mountain Radio Rigrunners ( http://www.powerwerx.com/west-mountain-radio/rigrunner-4005.html ) to distribute my voltage and protect my devices on solar installs. Makes for a nice clean, easy-to maintain and troubleshoot install. They go up to 38 volt, even though they don't say that in the descriptions. I bought some radio shack 276-1143 diodes - 200V 3 amp ( http://www.radioshack.com/product/index.jsp?productId=2062578 ). I crimped a red Anderson powerpole connector ( http://www.powerwerx.com/anderson-powerpoles/powerpole-sets/15-amp-red-black-anderson-powerpole-sets.html ) on each end of the diode after shortening the leads a little bit. Then I put that inline between my Rigrunner positive terminal and the cable that feeds my Mikrotik device. I label the end that goes to the Rigrunner - the side of the diode without the white stripe - with yellow tape so I don't end up putting it in backwards later. I use one for each device. Drops the voltage around .6 - .8 volts, enough to give me the margin I need on my radios. On routerboards that are very close by (no voltage drop due to ethernet cable length) I put two of these devices in line to drop it 1.2v. I'm cleaning out the local radioshacks and building a bunch of these for future use. Randy -- Randy Cosby Vice President InfoWest, Inc 435-674-0165 x 2010 http://www.infowest.com/ WISPA Wants You!

Re: [WISPA] powering finicky mikrotiks on 24v solar - $2.75 solution
Fine business using the diodes to drop the voltage. Many silicon diodes will show a higher voltage drop as the current increases. Depending on the circuit you were measuring, one with higher current would show a larger drop. That is an innovative use of diode voltage drop.

Re: [WISPA] powering finicky mikrotiks on 24v solar - $2.75 solution
Be careful using those diodes at sites where you're colocated with a high powered transmitter. The diodes can do some weird stuff (rectification, mixing) and could become a hidden source of interference/noise.

Re: [WISPA] powering finicky mikrotiks on 24v solar
Following up on this topic, I've received a couple suggestions for dealing with this on existing equipment. From Mikrotik Support: You should do the following, cut positive wire from the battery and add diode like this http://search.digikey.com/scripts/DkSearch/dksus.dll?Detailname=STPS8H100FP-ND (reverse voltage at least 40V, forward current at least 2A, forward voltage drop 0.6-0.7V) or similar diode. It should help to improve current behavior. Regards, Sergejs From a forum member: (To shut off over-voltage protection (at your own risk) ) Nearly from power Jack you can find SO8 package with 9576 label. Solder tiny wire between 1 and 8 pin. ( First pin marked with dot ) On my RB411, this SO8 package is labled Q801 on the board. -- Randy Cosby Vice President InfoWest, Inc 435-674-0165 x 2010 http://www.infowest.com/ WISPA Wants You!

Re: [WISPA] powering finicky mikrotiks on 24v solar
good idea, but not too power efficient. Steve wrote: I was not so happy either when I found out the newest line of MT boards didn't work on my already functioning 24vdc system. I have however been successful with a simple LM7818 regulator with a couple of tantalum caps and a good heatsink to drop voltage from ~26v supply. They are 1 amp, and I am using a 493 with 2 high power cards. all seems well so far. it's on a mountain and i don't look forward to winter maintenance. extremely cheap solution if you are handy with a soldering iron.

Re: [WISPA] powering finicky mikrotiks on 24v solar
I know why it was done, I just wish it wasn't that way. Bell Labs got it right the first time with the 48VDC POE system. Independent of line length, 48V POE just works. I've solved my problem with a 48VDC to 24VDC 18W converter that I add when I build my tower gear. Adds about $15 in parts to the unit, but a bit of labor to build. I also found a 21W 48VDC to 12VDC POE that works well, too. Adds $22 to the price, but is much quicker to build. For CPE equipment, I don't care about the POE voltage. I never put CPE gear on cables longer than 100ft. But I have towers with 50ft of cable and towers with 300ft of cable. I found answers that work for me. I'm sure others have their own answers. Eje Gustafsson wrote: That would mean increased cost on the units. People is more interested in price and MT products not capable of 48VDC and the sale of them caused such a dip in the 48V MT products that the 48VDC product line became too expensive to produce due to lack of quantity so choice was either increase price or drop the line. So the product was dropped because increase in price would mean even more people felt the advantage wasn't enough to justify paying that much more which would lead to even lower sale which would increased the cost and there is a level when producing a product does not become economical because the quantity is not enough. On MOST of their products we can do a special order MOQ 100 pcs last I checked at a slightly higher price than previous list price. Got need enough for 100 pcs RB532 or 100 pcs RB100 series boards. We still have RB230's left. Or of course you could buy RB600 which handles 10-56V on power jack or 38 to 56V on POE port. So you actually do have one option still available that gives you a powerful unit that is still manufactured and sold. So I guess comes down to how much is it worth to you the option is STILL there but I would assume you want the 48V option on the lower cost routers and that will not happen because that is ONE of the reason the products are cheaper. That said the choice is up to you actually since the product is available. / Eje From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Blair Davis Sent: Wednesday, October 28, 2009 1:53 PM To: WISPA General List Subject: Re: [WISPA] powering finicky mikrotiks on 24v solar I want MikroTik to go back to 48VDC!

Re: [WISPA] powering finicky mikrotiks on 24v solar
I ran into a problem with one of these yesterday that makes me leery of using them again. http://www.mouser.com/Search/ProductDetail.aspx?R=SD-25B-24virtualkey6343virtualkey709-SD25B-24 If the amperage goes over the rated max (1.1A) it appears the unit continues to allow dc through, but does not regulate it any longer. So in my case, I had a well-charged battery powering a mikrotik rb450 as well as a couple Trango AP's (with the infamous heaters). When I plugged in the second AP on a cold day, it momentarily caused the draw to go higher than 1.1A. 28+ volts started flowing through the regulator and caused the RB450 to go into overvoltage protection mode (ie: dead in the water). Will be trying out the Tycon Power and the Packetflux devices shortly. If Mikrotik comes out with another Routerboard that has 28v overvoltage protection... What a waste. Randy Randy Cosby wrote: http://www.mouser.com/Search/ProductDetail.aspx?R=SD-25B-24virtualkey6343virtualkey709-SD25B-24 This is one I have tried at another small site, and it seems to work well.

Re: [WISPA] powering finicky mikrotiks on 24v solar
I hear your frustration but I would not be yelling at MT. If I bought a regulated power supply that didn't deliver the set voltage I would be all over that manufacturer. Your RouterBoard worked to specification and the power supply didn't. Who is at fault?Really surprises me that it is a Meanwell unit that did that. I have had great success with the AD155 units. They are AC-DC, with built in battery charger. Now I do agree it would be nice if the overvoltage detection would turn the unit back on after an overvoltage condiditon. Based on the wide input range the RBs accept, I doubt that it is an easy engineering change to raise the overvoltage limit. What I really liked were the boards that gave an input option, 12-24 and 24-48 which actually had some overlap. Made power supply selection much easier.

Re: [WISPA] powering finicky mikrotiks on 24v solar
I use some Cincon Part EC4BW12, dc-dc convertors for anywhere I need to power the sub 28v devices. It will take 18-72 v in and output 12 v. I've had to install a lot of these as most of our sites were 48 v. When we started replacing 532's with the 400 series, we had to put one in for every board. They are solid devices and I get them from Mouser (sorry, don't have a mouser part handy).

Re: [WISPA] powering finicky mikrotiks on 24v solar
Soldering iron. We just split the cat-5 appropriately, solder the wire on and wrap them up in electrical tape with a Cat-5 jack on one end and an RJ 45 on the other. This way we can just plug-em-in inside the enclosure when we get to the top of the tower. Cameron Randy Cosby wrote: Looks nice. How do you connect to that?

Re: [WISPA] powering finicky mikrotiks on 24v solar
That would mean increased cost on the units. People is more interested in price and MT products not capable of 48VDC and the sale of them caused such a dip in the 48V MT products that the 48VDC product line became too expensive to produce due to lack of quantity so choice was either increase price or drop the line. So the product was dropped because increase in price would mean even more people felt the advantage wasn't enough to justify paying that much more which would lead to even lower sale which would increased the cost and there is a level when producing a product does not become economical because the quantity is not enough. On MOST of their products we can do a special order MOQ 100 pcs last I checked at a slightly higher price than previous list price. Got need enough for 100 pcs RB532 or 100 pcs RB100 series boards. We still have RB230's left. Or of course you could buy RB600 which handles 10-56V on power jack or 38 to 56V on POE port. So you actually do have one option still available that gives you a powerful unit that is still manufactured and sold. So I guess comes down to how much is it worth to you the option is STILL there but I would assume you want the 48V option on the lower cost routers and that will not happen because that is ONE of the reason the products are cheaper. That said the choice is up to you actually since the product is available. / Eje From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Blair Davis Sent: Wednesday, October 28, 2009 1:53 PM To: WISPA General List Subject: Re: [WISPA] powering finicky mikrotiks on 24v solar I want MikroTik to go back to 48VDC!

Re: [WISPA] powering finicky mikrotiks on 24v solar
I was not so happy either when I found out the newest line of MT boards didn't work on my already functioning 24vdc system. I have however been successful with a simple LM7818 regulator with a couple of tantalum caps and a good heatsink to drop voltage from ~26v supply. They are 1 amp, and I am using a 493 with 2 high power cards. all seems well so far. it's on a mountain and i don't look forward to winter maintenance. extremely cheap solution if you are handy with a soldering iron.

At Digikey or Mouser you should be able to find something similar but switching type that has a higher efficiency and current rating. I've used some modules for other voltages and they work great.

Re: [WISPA] powering finicky mikrotiks on 24v solar
These guys have dc to dc converters. IIRC, some are 90%+ efficient. I have used their stuff in my solar deployment. http://www.solarconverters.com You can buy their stuff at several online solar stores. Jason Randy Cosby wrote: What do you use to convert? The tycon power item Jayson pointed to is only 75% efficient, and only can handle up to 1 amp of load (a little too small for me). http://www.tyconpower.com/products/POE_Inserters.htm Any other solutions?

Re: [WISPA] powering finicky mikrotiks on 24v solar
http://www.mouser.com/Search/ProductDetail.aspx?R=SD-25B-24virtualkey6343virtualkey709-SD25B-24 This is one I have tried at another small site, and it seems to work well. Hoped I could find something a little better amperage. The next bigger one these guys makes is too big, and has a fan that runs all the time.
