Sundown Amp Clamp Tests

Recommended Posts

I was wondering if you've tested th sax1200d, I'm putting it to 2-sa12's...

IIRC it did rated power with a rise to 2 ohms, or something along those lines. It was in a thread a while back, possibly the thread Jacob started when it first came out.

Edit: I found the thread. Here's Jacob's quote:

Two Stinger SPV-70 Batteries / 40-amp Power Supply / 8 awg wire power and Ground (this amp should have 4 awg)

Wired to 1 ohm nominal :

1170 Watts @ 12.5 volts

1.97 ohms after impedance rise

Wired to 0.5 ohm nominal :

1490 Watts @ 11.1 volts

0.85 ohms after impedance rise

---

Measured with my Extech True RMS power clamp meter several seconds into the tone @ 60 Hz -- this typically reads about ~15-16% less than a "dual peak hold" amp clamp test.

We'll do some more testing with a more adequate power wire coming up soon. The test bench 4 awg has the ends tinned so is a bit too big to go into the SAX-1200D terminals -- will need to get it in a vehicle.

Thanks guys! So it should do fine with 2sa12's until I jump to the 1500d

anybody measure the amp draw of a 3500d anywhere from .5 ohm to 2 ohm?


I don't fuck around. I go from zero to I hope you die in less than 2 posts

ah, how did you come up with a power figure for one of those amps if you didn't measure thee output voltage or current?

your tests seems rather flawed to me.

The Extech calculates power (watts) automatically without separate voltage & current readings. It is a very nice and accurate meter.

I'm pretty sure I know how to clamp amps :drink40:

In any event -- this is the meter :

When compared to traditionally utilized separate meters this meter reads lower 99% of the time as the meter captures the actual power at any given moment. Separate readings can have a time variance; especially dual peak-hold which can be drastically off.
