Damaged Orthagon radio
Damaged Orthagon radio
(OP)
In the process of fault finding a damaged 2.4GHz radio i found the following voltage reading on the input to the radio PoE supply.
L-N = 106v
N-E = 63v
L-E = 63v
could this N-E be part of my problem. The supply voltage device is a coleman 400Watt inverter, any advice on the use of such to power my radios?

RE: Damaged Orthagon radio
You have to be careful here. The 63V is a value that can be present due to small leakage currents. It can also be caused by noise filters that are improperly grounded.
How exactly did you take the measurements and what with?

Then make your measurements.
Tell us what you get.
Let me also say that personally, I would never use Coleman generators or inverters. Our local radio amateur group set up an emergency services practice day using their club-bought new Coleman generator. Right in the middle of the event it started putting out 190V and fried everything! I then heard about another Coleman generator doing it again. I believe they make them very cheaply. Need stoves and lanterns? They make great stuff! Electronics? Not me.

I buy those higher end UPSs and they often have adjustable voltage trip points.

I use the APC RS1500 with the adder battery bank. It will run this computer and a fluorescent ring lamp for about two hours.
It has never given me any generator problems. My home office UPS is an APC Smart UPS 1400. It has had three different generators run thru it with no complaints. Interesting problem you've had. Sorry to hear.
I hate it when the power goes off, on some primal level. I usually go into a generator-UPS frenzy when it happens to appease myself that "I can make the power if I have to".

RE: Damaged Orthagon radio
i am interested in the added battery solution, i have already replaced the Coleman Inverter stuff with an APC 1500VA UPS. i however, have three 13 plate 12v batteries sitting around from the previous set up, can i hook these up to the APC with ease?
RE: Damaged Orthagon radio
Now if you (somehow) mean 12V Lead Acid batteries;
Theoretically you can...
Practically maybe not a good idea.
Reason: Typical UPSs are a designed system. The battery/s are part of the ground up design. The charger circuits are designed for the included battery/s not for a bunch of added on capacity. You could burn out the charger circuitry. You could have other problems too, like recharge rates in the days instead of hours. The last thing is free standing batteries are frankly dangerous. Easy to short, easy to explode.
The unit I mentioned above is designed to have 4 more batteries added to the system besides the two in the system. This "type" of UPS would probably be more amenable to excess added batteries.
If I were going to do this I would get a multistage charger for my batteries and an inverter to run off the batteries.
Also you should NEVER EVER mix battery types in any system.

For the clarification. the APC 1500VA without addition will form my final hook up. Thanks to all others who assisted as well.
