The higher the voltage the higher the Hashes you can have, that is why I want to connect to 22ov.
In my country common houses have 127V (Single phase- neutral - ground), I can use a voltage transformer to obtain 220V (Single phase- neutral - ground) and that works well except that the transformer are expensive and generates a lot of heat.
What I want is to use 2 phases to obtain the 220V (biphasic). But I have 2 problems.
- Bitmain told me that the antminers works in monophasic (Single phase- neutral - ground). But I heard of people that has been working with biphasic (2 phases).
- To connect with two phases. Should I use (2 phases- neutral - ground) or (2 phases - ground)?
Is is safe to connect the antminers to 2 phases?
"What I want is to use 2 phases to obtain the 220V (biphasic)"
No, you are STILL using just 1-phase that has been split into 2 lines
https://en.wikipedia.org/wiki/Split-phase_electric_power and that is why the miners PSU's work fine. All you connect is line-to-line and ground, no neutral connection used.
Split-phase 120/240v is entirely different from 3-phase power
