Title: Electrical hazards Post by: m4rv3 on April 23, 2017, 02:10:02 AM Over the past couple months I had been experiencing some problems with my miner not working at its optimum speed however, yesterday I fixed it. (One of the wires to the second fan was damaged)... Now that it's fixed its working at its full potential..
It is an S7 running at 4.6Th/s Apparently, now that it's running at its full potential, it's drawing more current. I had it connected to a 2000Watt transformer last night and one of the sockets to the transformer melted. I switched it to another location today using a bigger transformer (3000watts), only to know after a couple hours of mining, the transformer burnt out. Has anyone been experiencing these problems and how we're they solved? How do you have your miners connected?

You need to let us know what transformers you were using as the overall rating alone doesn't give enough information.

Pretty much every "World voltage converter" I have come across is a highly under-rated piece of sh*t that uses far too thin wire for the winding's along with paper insulation. Use a REAL 120/240V industrial rated transformer. Yes they are about 2-3x the cost but they are bulletproof. Proper size wire and core construction, generally potted in resin, UL-rated, etc...

Yes this is similar to the type of transformer I was using. I will look into the one you recommended. Title: Re: Electrical harzards Post by: xhomerx10 on April 23, 2017, 02:49:15 AM Why would you want to step down the voltage from 240 to 120?! Most power supplies are more efficient using 240V.

The power supplies I have are 110v Title: Re: Electrical harzards Post by: xhomerx10 on April 23, 2017, 03:03:00 AM Are they cheaper than 240 volt power supplies + a step down transformer?
Title: Re: Electrical harzards Post by: m4rv3 on April 23, 2017, 03:15:48 AM Are they cheaper than 240 volt power supplies + a step down transformer? I got these together with my miner when purchased. Never considered it to be a problem until now. Now I will definitely either look into industrial grade transformers or get 240v power supplies like you suggested Title: Re: Electrical harzards Post by: veleten on April 25, 2017, 06:07:41 PM Are they cheaper than 240 volt power supplies + a step down transformer?

Now I will definitely either look into industrial grade transformers or get 240v power supplies like you suggested very strange,did you buy your miners from an oficial suplier or second hand? if I'm not mistaken,no site is selling 110v power supplies with the miners also you should be better off buying a 240v supply instead,if you ever deicde to buy additional miners you will get a 240v from the get go and don't have any troubles with transformers and converters |
