Re: Power supply fuses

 

Hello?

For my uBitx I use a Pacific Antenna kit named VoltTattler.
This montage has the following features:

- Simple through-hole construction
- Draws only around 1 mA in normal use.?
- Reverse polarity protection.
- Programmable Thresholds over a range of 4V to over 27V.
- Single button programming with audio feedback.
- Audible announces activation with power on and indicator with LED flashing green.
- Audibly announces by Morse code when input voltage exceeds user programmed thresholds.
- Flashing Red and Yellow LEDs indicate that a voltage limit has been exceeded.
- 3V digital status signals are available on a header
- Cheap protection for low voltage DC equipment.

interesting to avoid inversions of polarities and portable QRP, in battery operation to know the state of health of your batteries.

The "Fix reverse polarity" section on suggests a 0.5A fuse for the "rig" and 2A fuse for the "finals," but does not specify which wire is which.? The schematic says that the brown wire is "PA-PWR," but I am too much of a newphyte to be certain if this means the same as "finals" or "rig."
