Had an odd failure yesterday...
Went into my 'power room' and about half of my voltage and temperature displays were off!  Inverter was running fine, batteries were charging, water heater was up to temp, but no indicators!

Turned out it was one of my (formerly) faithfull 12v dc-dc power supplies.  Oztules pointed me to them years ago for low cost, trouble free, reliable 12v from 48v power to power my controls and indicators.  I'm using 5 or 6 of them for various things.  They used to cost about $5 USD.  Just looked and the cheapest comparable I found is this one at about $7.50;

There are some without a enclosure for about $4.50 but they are differently built, and possibly not as stable.
The one that died looks like this;
It had been working for over five years. Not smoked so suppose the 12v regulator just quit. 
Interestingly, the new one I tried wouldn't work on my 24v bank like the old one had been doing, so had to power it off of my 48v bank.

So indicators and fan controls all working again.  Hopefully won't lose another one for five more years.  I have a couple more that have been operating for 3 or 4 years so will have to keep an eye on them....
We're all going to DIE!  (eventually)
