Proffieboard Current Draw?

1

What’s the approximate current draw of the Proffieboard itself?

The reason I ask is I’m doing an install in which future maintenance will be easier if I can use a micro JST connector for the positive line to the Proffie from the kill switch. The neo connector will be wired straight to the battery, so it’s only the board positive going through the JST. I would use the four way JST pictured, with one pin for speaker +, another pin for speaker -, and the last two pins both carrying power from switch to board to share the load.

Do we think it will handle it, or is it marginal?

I wouldn’t normally entertain the idea, but the quick disconnect would be handy, especially as this chassis doesn’t allow access to the Proffie buttons without removing it. I would also then use a Deans Micro for the battery positive and negative - but that one would be carrying the pull power.

So what do we think - safe and sound, or marginal and mad?
Any thoughts welcome.

You’ll be fine.
You can measure the draw by inserting a multimeter in the circuit between the battery and board.

NoSloppy’s comment is basically right.

The board can draw as much as ~2A, with spikes up to 4A. The actual current draw depends a fair amount on your volume and speaker. Most people don’t push it to the max, and the draw is then closer to 1A than 2A.

Since we use low voltages, it’s usually fine to go over the current rating of the connector a bit, but how much is not really known. I would stay away for connectors rated for less than 1A though.

Thanks guys.
I seem to recall reading somewhere that these JSTs are rated for one amp, but I guess that’s per pin, so I have two amps to play with . But as you say Prof, that rating is most likely at a higher voltage which gives me a little more headroom.
Sounds like I should get away with it. :smiley:
Thanks again guys! Much appreciated. :+1: :slight_smile:
