psu voltages of x150 x250 and xa30 x60?

[rhythmsandy]

what voltages are used for the x150 x250 and xa30.5 x60.5? how much is this different from the f5? does anybody knows about the psu supply voltages for the above models?

 

[AudioSan]

XA30.5 have about the same supply voltage as F5. all others are way higher. that is a must to reach the higher power.
but i can't understand why you ask about this?

 

[rhythmsandy]

to compare how commercial amplifiers are using class AB voltages and about the pass amps using the psu..

 

[AudioSan]

they are all locked to follow ohms law.

 

[Zen Mod]

X150 : +/-35Vdc
X250 : +/-45Vdc
XA30 : +/-25Vdc
XA60 : around same-ish

 

[AudioSan]

ZM. so XA60 is 2 bridged XA30's?

ZM. so XA60 is 2 bridged XA30's?

huh?

 

[AudioSan]

as i understood ZM. the XA60 has the same rail voltage as the XA30.
if thats the case, the XA60 most likely is 2 bridged XA30's.

Hmmm. Maybe different topology.

 

[Zen Mod]

maybe is just more juice ?

ever read tests and measurements of smallest PL amps ?

they're named as smallest either by mistake or from fun
dunno , I'm just small Babelfish here , better to ask Mobi-Dick itself .

you can call me Ishmael

 

[buzzforb]

I am not sure he would like being called that.

 

[Zen Mod]

he like whales

 

[buzzforb]

Can call them out of the water, from what I have heard.

 

[Zen Mod]

naah

he's doing just the opposite , all these years

ya wakooyank

 

[buzzforb]

Very good, indeed.

Since the psu looks way too low for the power it delivers.
for a 150w class AB is it just 35V? since there will be losses...

where did u get these psu values?

 

[Zen Mod]

you know that all these amps are bridged , in topology ?

values I got ...... according to prior posts , I fished it

(having little spy bird in PL , and measuring thing or two , prior to scorching items in Official PL Disposal Facility )

ohh are these bridged? it means that each of the bridged is capable to drive in 2 ohms is this possible because of many output hexfets?

so X150.5 has total 20 IRFs on the output per channel so does this mean 5 x irf240 and 5 x irf9240 and having such two modules bridged?

 

[Zen Mod]

we are asymptotically closer and closer to point where I don't remember these details , so you'll have to make your own google images search .......



whatever - you have overall picture - put them plenty and you'll have whatever you want

yeah you are very good at fishing

but i have a doubt regarding the irfp240 9240 considering if we have 10 pairs at the output so using it at +/-45v will the amp be stable in 4 ohms after bridged?
