what are the duty cycle rattings on the saz1500d ?

and at what wattage are they 100% duty cycle ?

thanks

What do you mean by duty cycle? They do full rated power (1500WRMS @1ohm) @12.8v and more at higher voltages.

so i could play a 50hz test tone

at 1500 watts rms

non stop for 24 hr

without any damage , excess wear or tear or over heating ?

that would be 100% duty cycle.

if it could only do that for 1 min on 1min off 1 min on 1min off ect.........

then it would be 50% duty cycle.

if it could only do that fo 1 min on 3 min off 1 min on 3 min off ect ......

then that would be 25% duty cycle

and just because it puts out more than 1500 watts doesn't mean that it can do it at 100% duty cycle.

it might only be able to put out 1000 watts at 100 % duty cycle.

or what ever it is.

i'm sure sundown already tested this and has average numbers for theese amps.

i have a feeling that it is 100% duty cycle at full unclipped power

but wanted to know for sure.

i don't use all 1500 watts and have never been able to get mine above room temp.

Audio amps are usually rated for continuous operation - you hear about duty cycle all day long for rating RF amplifiers, because the transmitter isn't actually modulating the input 100% of the time in some modes, but it isn't a commonly used term for audio amps.

thanks RIckRolled for the response

i actualy come from a rf background

i bet that your correct about sundown having 100% duty cycle

even though i dont use mine anywhere near full power or for any real amount of time at once

a time could come up that it could happen and if i know that it is rated for it i would have no problem doing it.

but if it is not 100% duty rated then i have no problem staying within spec

all my setups are set with an o-scope and then turnd down to where i want to hear it.

i buy sundown products not because they are under rated but because they are over built.

Nobody has thermal issues with 1500s that I'm aware of... especially not with the new heat-sinks.

why does it say rick-rolled when i typed jim-j

It's a secret

He's got a filter thingy on it, I believe Mark put it on for him.

RIckRolled?

haha just wanted to see.

I've pounded on an SAZ-1500d for over an hour in the texas heat (105 degrees)..didn't shut down. Unless you are going with RF's Type RF stuff, you'll find that Sundown is a much beefier product. The 1500d is pretty heavy. In fact, it weighed and little more than my US Amps USA-2000x.

i ran to austin today pounding on the hwy for 30 mins there... 30 mins back.... no problem.

the other night i ran hard for almost 2 hours non stop

RF = radio frequency, not Rockford Fosgate

oh I'm not worried about it taking the abuse playing music

music has a very short duty cycle built in already

and i'm old in comparison to alot of you so i can only handle so much

not that my system doesn't rock but i can't handle that all day. <i gota be able to see staight to drive>

but i am an e-tech and just wanted to know the specs on duty cycle.

and i'm weird, a day could come that i might want to dump 1500 rms at 30 hz for a day, and have nothing to do with car audio or music.

rf = radio freq , like comunications

i hoped it was just a filter thing thats why i put the - in jim-j the second time.

just noticed the alteration of my post.

now for you guys that wang full tilt for an hour or more do your amp even get warm or hot ?
