SO I love the 433AHs but… If they receive an over-voltage of close to 28+v then they shutoff. So here in the South West where the sun can be very brutal our array can push close to 30v which has caused our 433AH and 493AH to shutoff. The solution to this situation is a physical hard unplug to restart our MT. We discovered this to be a problem so at one site we had to regulate the voltage so that it is no more than 28 volts. This costs us a whole new piece of equipment called an RMS with some additional resistors to lower the over voltage issue. While… Our older 532 and 333 boards seem to be a lot more tolerant to over voltage issues and under voltage issues.
Any other suggestions to help regulate would be greatly appreciated. Can we expect that all new products of the Routerboard will come with this deficiency? Or is their plans to reintroduce the voltage regulator that seems to be missing from the newer Routerboards.
A few 1N4001 diodes in series between the supply and the router should help. That should drop about 0.6v (600mv) per diode. Three in series should drop about 2v.
Mine doesn’t suck at all. I use 12 volt equipment.
It’s good S.O.P to regulate the voltage going into your gear, just because the older boards could handle voltage’s outside their normal range doesnt mean it is good for them
My thoughts exactally! We use 12v everywhere and a voltage stepper like this one (http://www.virtualvillage.com/12v-to-24v-dc-dc-power-converter-module-003602-013.html) which works very well. We usually set the output voltage to 18V (almost everything will work with that) and it dosent matter what the input voltage is, it will still output 18V (tested it with a 5v-2A power supply and a 12v battery output voltage remained the same). Not sure if the stepper will step down IE 24V IN and 12V out.
