Power consumption of power amps. Panu ma compute?

[dakilangpatricio]

Sir, gusto ko po sana malaman ilang watts/amps ang kain ng kuryente mga amps ko. .
Kasi mag rebuild ako ng power distributor ko kasi nagdagdag na ako moving heads ( i popost ko later pics, panala at mura pa weinas m575A)

ETo po mga amps ko:

LIVE FET450 450W @ 8omps per channel
LIVE FET650 650W @ 8omps per channel
LIVE FET1000 1000W @ 8omps per channel

kasi po diba P = I x V ang formula. . salamt po
para alam ko kung panu ko hahatiin mga breaker sa distributor. .

Plan is:

100A na breaker for main, then un hahatihatiin ko. . salamat

Sana may makakasagot nito?  maths to preng...

di kasi specified ang current draw ng china amps eh kaya di makita, unlike sa u.s. brands nakaspecify,

pero sa tantya ko safe na 30 amps dyan.

[dakilangpatricio]

cge sir. . thanks. . 30 amps na breaker gamitin ko for power amps . . or much better ung power distributor ko lagyan ko ng ampere meter db. . hehe. .

mahirap malaman un

kaylangan alam natin yung input ampere ng primary sa transformer, at ilang ampere yung output ng transformer, 

sana my mag bigay ng info dito

gummit ka ng power meter na tulad nito:

wattage in total:

[eirol_99]

open your power amps, nakatatak ata yung Volt-Ampere (VA) rating ng toroidal transformer nya dun, divide mo na lang ng 220 volts,

i think the thread starter would like to know the actual power consumed in operation, so a watt-meter is the right instrument to use....

i heard that watt-meters can be purchased at ACE hardware and costs less than 1k, i got mine for more from Tipidpc...

ok sir, ilang watts po kaya nyan? nice toy, pero mga power distro is ammeter nakalagay sa panel nila.

direct reading na ito, in the picture i posted, line voltage, curent, frequency, power factor , apparent power and true power can be diplayed...

Sir dakilangpatricio mag ask ako sa china para sure ka kung ilan ampere ang bawat isang amp.

assuming efficiency of 70%:
LIVE FET450 450W @ 8omps per channel ======> 900/0.7 = 1286watts, @220volts, is 5.8amperes
LIVE FET650 650W @ 8omps per channel =======> 1300/0.7 = 1857watts, @220volts, is 8.44 amperes
LIVE FET1000 1000W @ 8omps per channel =====> 2000/0.7 = 2857watts, @220volts, 12.98 amperes

they can be accomodated in a single circuit of 30Amps......however if you have lots of them, then its another story....

remember that circuit breakers are there to protect your cables from burning,

gusto ko yung flash mo sa gilid brad... sine wave na may harmonics ba?
