...

Also i am asking you guys to tell how much a antminer s9 is gonna produce in a day.

Today PPS TH/s Earnings is 0.00115679 BTC for 1 TH/s

S9 11,8TH/s
11,8 x 0.00115679 =0,01365 BTC per day (today)

what is the power factor. Huh

if you got a power factor we can come up with a approximate value

also without power factor the voltage results would be in infinity also you mentioned a watt value and not a kilowatt value

1300W in hour

24 hours x 1,3 kw =31,2 kW/h

Risking a smack, Bitmain's spec for the APW3-12-1600 PSU specifies output at

DC Voltage
12V
Rated Current
133A
Rated Power
1600W

If there is a DC supply capable of providing that, why can someone not just go DC/DC direct connection?
i.e. battery/solar power without the conversion to AC and back again to DC thru a PSU?
Just asking...

That is done all the time with telecom equipment.
The only trick is to match the DC feed to what your buck regulators want to see. In fact many data centers are now using a high DC feed (typically around 380vdc) to the racks and then chop that down to what the servers need.

Technically, you could bypass the AC input rectifiers and just feed the DC to the primary side filter capacitors...
Of course, as always: IF YOU PLAY WITH LINE POWER SIDE OF A PSU -- KNOW WHAT YOU ARE DOING OR YA MIGHT GET KILLED.....

For single phase 1 kw as 6.25 amps and power factor 0.9 it is 177 volts daily not bad.

Why i must read those law's , you guys are always there to help me out and do the math lol

so 177 volts a day is not bad unless in 4 days it consumes 2 months of my eb bill rofl .

You should read up to learn.
Cuts down on folks wanting to give a smack upside the head....

... DC does not travel well over distance ...

Your statement is simply not true.

Yes, it is.

Quote

DC installations are very expensive, which is one reason why they don't really get used below transmission voltage level. A DC substation requires more equipment than an AC substation would require, partially becuase the conversion process requires equipment that will eliminate harmonics that are created. This is very inefficient for subtransmission and tranmission voltages below 500kV (500,000V).

We are talking about residential 240V AC power & not 500KV of power transfer.

Anyway, it's got boring now....... Roll Eyes

Hey tharani, if you want to know how much your S9 will cost to mine how much, use http://www.coinwarz.com/calculators/bitcoin-mining-calculator , fill in the relevant values of your miner, plus your electricity cost (iirc, Delhi, for example, is about $0.06 per KwH for a medium size user) and you will get your answer.

i just wanna know the correct current costs

for ac single phase

i don't know correct factor.

My s9's each pull around 1,300w.
From a 208VAC line each pulls 6.25 Amps.

The PSU's for these are small enough that they are all single-phase.

what is the power factor. Huh

if you got a power factor we can come up with a approximate value

also without power factor the voltage results would be in infinity also you mentioned a watt value and not a kilowatt value

Where are you getting these ideas? Huh

?
1,000w = 1kw
Power factor is apparent power/real power. It has nothing to do with this discussion and is generally always assumed to be a value of 1, For acedemic and nit-pickers however most good PSU's have a PF of around 0.9

Dude (or dudette) - read up on basic Ohms's (for DC) and Watt's (for AC) Laws

Extremely sorry guys for saying power supply is dc power supply in india is ac

also i will double clarify before having posted on here.not from just getting info from a oversmart/overenthusiastic person.

1 or 3-phase only matters in regards to what the utility charges you. In urban areas a general rule of thumb is that if it is a commercial/industrial user and they require more than around 50kw it will generally be 3-phase power supplied.

Fine. AC, DC, whatever. To makes things easy, let's use water as an analogy to electricity:
For water the amount of force it has is measured in PSI, kPa, whatever. For electricity the amount of force is Volts.
A quantity of water is gallons, liters, drams. A quantity of electricity is Amps.

Now comes where the confusions seems to be: The amount of WORK the volts and amps together produce. The unit for that is Watts or Joules and has a simple formula. Watts = Volts x Amps and the rate of use is Watts/time

Everywhere except apparently India the electric bill of all consumers be they residential or industrial is based on Watts - from an AC source - consumed. For most loads this will more or less be a constant value regardless of what the line voltage does because generally if the line goes low the load will try to pull more amps to keep power constant (for motors and non-incandescent lighting).

... DC does not travel well over distance ...

Your statement is simply not true. The power loss experienced due to long distance power transmission is less for DC than it is for AC. The issue is that DC is typically harder to convert to higher or lower voltages. DC voltage conversion is also traditionally more expensive, but there have been recent advances that should bring the costs down. There are other considerations in the AC vs DC war with regard to basic electrical theory, but we are already quite off-topic.

I suggest that folks interested in learning about AC vs DC power transmission read the article in the link below as it explains some of the basic pros and cons.

http://www.theenergycollective.com/roger_rethinker/204396/ac-versus-dc-powerlines

the calculations were based on the kwh to volt converter for dc current.

http://www.rapidtables.com/calc/electric/kw-to-volt-calculator.htm

input the kwh and amp

this is not off topic it is about the power supply needed for the s9 only

and we are discussing about the pros and cons of it.

i inputed 5.1 amp for the provided kwh also i told you it was a test value .

what use is it it has to run for 12 months to get back the 3000 dollars and also pay the electricity bill for it and mine about 0.1 btc per day.

IMPORTANT UPDATE

IT IS AC FOR RESIDENTIAL

DC FOR INDUSTRY

If commercial supply comes under residential it is ac then

IT IS AC

FINAL

SUPPLY UNTIL TO THE PLUGPOINT FOR RESIDENTIAL IS AC

DIFFERS UPON THE POWER SUPPLY UNIT YOU ARE USING .

OK GOT IT .!!!!!!!!!!!!!!!!!!!

NO CONFUSION

The overenthusiastic friend of mine had calculated according to usage of ups he does not know much about psu's or miner's

he says that the current supply will be ac until plug point and when it reaches some devices the adapter converts it to dc.

So he thought the input was in dc which i clarified it with him today.

SO UNTIL PLUGPOINT IT IS AC
