Thanks for that...
So the 10 I have set up in my front room on a circuit with all my other living room electricals is overloaded then?
Only 10 per 20 amp breaker ? So 50 in a house ? With the house only being allowed 100 amp max?
My father who used to be a sparky on planes informed me it was amps to worry about, not volts, it was he who said these run on 12v so many would be fine...
Thanks
Anyone know how many of these I can safely power on a 20 amp breaker ?
I am useless when it comes to working this out.
I was told many would be fine due to using 12v.
But I would appreciate someone in the know answering.
Thanks in advance.
edit: UK based, so 240v.
S3 uses 350W of power, stock. 20AMP is 4800W, so you can safely plug 12 S3s, to be on the safe side. Use a decent PSU, 80 Plus and keep it under 80% of PSU load.
Cheers
20A Breaker is for 240V
AC and Antminer S3 consumes 28A+/12V
DC in idle conditions.
Safe limit when setting a breaker is calculated to 125% load.
You should be conservative when sizing these things. Its not something like overclocking GPUs/ASICs
That means your can load a maximum of up to 16A in 240VAC that's roughly equal to 3840Watts power.
So, never cross
at wall power consumption over 3840Watts.
Assume a good power supply will
continuously deliver 80% efficiency and for running 1 S3 you need a power supply of minimum 425W.
So 425W is your at wall power consumption for a single Antminer S3.
Now its simple to calculate how many Antminers you can safely connect on your 20A AC breaker.
3840/425 = 9 S3. So, Keep a maximum of 9 Ant miner S3 on your 20A AC breaker. Anything above will violate your safety limits.
Using your maximum power of 240VAC/100A you may run up to 45 S3 (45=9*5).
Make sure you are deducting enough for other house appliances and keep your hour from a catastrophe.
