Re: TinyTrak4, bank switching
¿ªÔÆÌåÓýWhoops sent that too fast forgot the pictures. And the rest of my message. N 1 has the astron 12amp power supply on it, N2 has the the solar battery bank on it. And the other side goes to the tiny trak and a yaesu ftm 350.?
I do have all power stuff figured out as when the power goes out or I turn off the power supply it does switch to battery.? The relay drains power and I can watch the lights on the tt4 and the radio dim out, then the relay clicks over to battery.
That part works. Just trying to figure out if I take JP1 to anything on that board or the power supply if it will go hey! Not normal!?
Again thanks for all the help.?

The relay listed (SLA-12VDC-SL-C) as 3 variations which appear to be SPST Normally Open (N/O) for model -A, SPST Normally Closed (N/C) for model -B,?or SPDT (switch between N/C and N/O) for model -C.
Since only 1 pin is actually switched, my common ground? idea won't work.?? You will have to rely on some indicator on the board to tell which state the relay is in.? I didn't see one on the board you reference. If you give more details on your configuration we could give better advice: ? Vin to board from power supply ? Vin to board from relay ? Expected current draw from device(s) attached to output. Rob KB8RCO |
