Topic: hi guys i have electric 3 phase how much can i put each 1 phase take miners s9 (Read 1148 times)

I had 2 on each phase. But it depends on your amperage, how good the lines are, etc

thank you so much

Which S9 is also needed, what loss of efficiency the power supply does also needed (add roughly 10% to get an idea). The 14 TH/s uses 1,375w + 7% seems a bit optimistic for most power supplies (Titanium is min. 90-94% at 100% load), while the 11.85 TH/s uses 1,175w +... (that's about a 15% difference in power). At 1,500w each, that's about 12 x 3 = 36 at full load, but I don't think a 80A fuse is supposed to handle that full load 24 hours a day.

IMO you need some professional help or otherwise you could end up burning everything.

thanks everyone for the help
i have 3 phase each with 80A switch for each phase
the street fuse has 100A for Each phase
in this case how many miner can i load for each phase
thanks

13 miners (1300W) on each phase (230V)
Total 39 miners . But the 80A main fuse can begin to turn off , without extra cooling. I recommend a separate cooling fan for main fuse or less miners.

3-phase is pretty nice if you know how to manage it. I had 110KW of miners and general shop circuits running off 208V 3-phase (120V line to neutral) with only 6A of neutral current last time the utility guys came out to check. But that's not a n00b installation either, like this guy would probably end up with.

Here in the UK most properties have 100a 240v single phase supplies, however some larger buildings have 100a three phase 240/440v supplies which (in theory) you could hang 16 Antminer S9's off each phase giving you a total of 48 units.
HOWEVER...
If you suddenly butter up your three phase supply and max it out, you will cause the local substation to strain and could overload the service fuse for your street. (normally 400a) Most power distribution systems are not designed to be continually "maxed out".
Also if you pull let say 100a on one phase and nothing on the others it will cause an abnormally high neutral current and can in some cases cause the local substation "veer off" 50hz frequency. (can't remember if it pulls it up or down, that information escapes me)
Hope this information proves useful and that you stay away from the three phase equipment!
Edit: also the heat load from 48 Miners would be biblical, which you would need to take into account
Kind regard

3 phase at what voltage (volts)
and what is your Max current limit
and what is your Max current limit

^ What he said. You don't have enough information or knowledge yet.
August 06, 2016, 08:41:04 AM
The question is impossible to answer without knowing your current limits. 100A per phase? 200? 50?
If you don't know enough to know how to solve this question for yourself, I'd seriously reconsider spending money on... actually, pretty much anything.

In here, 1 phase is about 62A, I run about 8unit of s9 without a problem, but the wire need to be 16mm cable.

hi guys i have electric 3 phase how much can i put each 1 phase take miners s9
i need know how much take 1 phase 10 miner 12 miner 15 miner or more . down please tell me
