Amp hour draw of Raymarine Instruments

I'm sure I'll regret posting this but...

I'm looking for the amp/hours used on the Raymarine ST60 wind, speed and depth instruments and also their x-5 wheel pilot autopilot system (i know that one will vary greatly)

Drawing a big blank on where to find this information or how to calculate it. Any help would be greatly appreciated.

Just trying to figure out battery consumption..

Thanks in advance.

I don't have info to hand but would have at home. You will find it however if you go to Raymarine site and look through the relevent supporting docs for the products. You can download full manuals which is pretty much where I got mine.

Yep, this is why I said I knew I was going to regret the question. I have the manuals in front of me and have looked online. I'm just not finding what (I think) I need.

Freekin' old age is killing me... (and I'm not (too) close to middle age.)

Sorry, but if you happen to find it once you get home, it would be greatly appreciated.

Cant find anything in the manuals either...all three require a 5A fuse on the hot wire but that's not very helpful...probably can find it online or someone will have it I am sure...

I did not look in the manual, but I know Raymarine has great customer service I would just give them a call.

OK, I had a look at the manuals and I'm with you ... can find nothing re the instruments. OTOH wouldn't power consumption of instruments be minimal compared to other gear ? See below re the X-5 but fridge, chart plotter, computer if you have one on board, music machine, even lights if not LED are more of an issue.

One thing struck me however .... it is going to be pretty much impossible to accurately gauge the power consumption of the auto pilot. The manual says 200ma on standby which is all very well and good but consumption when working is variable depending on conditions and your setup. The final number is going to be somewhere between bugger all and a whole lot.

Re: Amp hour draw of Raymarine Instruments

FWIW:

I flipped on my nav instr breaker today. I've got an Airmar transducer, that feeds depth, speed & temp data to an ST-60 Tridata in the cockpit and an ST-60 Multi at the nav stn. I've also got an ST-60+ wind instr (display in the cockpit, and also feeding data to the Multi.

My battery monitor showed 0.3 amps being drawn.

Re: Amp hour draw of Raymarine Instruments

I looked on the West Marine site and the give a draw of 45mA for the depth finder and speed but nothing on wind although I would assume it too draws 45mA.

Re: Amp hour draw of Raymarine Instruments

My spare ST60+ Wind, instrument alone (no masthead unit connected) on a lab supply on my workbench consumes:

Backlight level 0 (off):

51 mA at 10.0 VDC
58 mA at 12.5 VDC
65 mA at 15.0 VDC

And at 12.5V, the various lighting levels draw:

L0 58 mA
L1 74 mA
L2 80 mA
L3 106 mA

This sounds reasonable re ebs001' figure from West Marine, as unlike the depth /speed, the Wind display does have a small servo/stepper motor to turn the needle (and make that little high-pitched whine heard late at night in very quiet anchorages.
