Topic: Any suggestions or experiences on using a voltage stabilizer/regulator - page 2. (Read 459 times)

Unless you live here with the cheapest electricity on the planet but end replacing PSUs every 3 months or so due to sudden fluctuations and blackouts. At the very least use a "protector" with an adjustable temporal delay, if you can regulate that even better so they don't all restart at the same time when the power goes and returns...

Note this is not about killing the asics, but the psu itself, assuming the PSU is doing its job properly...

If he lives in a "nice" country with a perfectly maintained and above 99.999% guaranteed service, then sure, there is no reason to "waste" your money with those.

You are correct that many asic boards die from excess humidity or dry conditions, but this is a separate issue: bad electricity. It exists.

Also to the OP, please don't use a stabilizer for each unit, as a massive amount of those can harm each other creating an unwanted (noisy) chain reaction (unless they have adjustable waiting timers to restore power, so you could adjust each one differently).

Bitmain has a few reported psu issues but nothing to be overtly concerned about. Philip took precautions but for more specific unit reasons than what you're asking here. I would approach with more narrow scope of model but in general there is no need for a stabilizer for most to all units.   

It's well known that power supplies are tested for voltage ripple etc, especially the high end ones.

I am not running many miner but planning to do so soon.

Any info on the fact that the psu regulates the voltage?

@ op  I have 1 stabilizer   was not cheap it was rated to run 2 s15's

it does keep volts at 220  with 228 to 246 in it is really close to 220 out.

it was poorly wired and will never run 2 s15's

it runs 1 s15 fine but cost was about 180 Usd maybe 162 with a coupon

since the unit works for 1 s15 well I found this one price was 121 with an offer
it claims to do 4000 watts which would be 2 s15's
it has not arrived.

if it is better built and does 2 s15's correctly it would only be about 61 or 62 an s15

that would be ballpark okay if you have power doing 243 to 252 a lot.

unit comes tomorrow.

Now only 2 or 3 psu's on s15's have been reported to die on this website.
assuming they are true reports the input volts were 243-246 for sure maybe higher.

this is a very small data sample.

I am far more certain that the power protection unit with the lcd screen won't do 2 s15's
since 14 gauge wire is not good enough to do over 3000 watts

I am less then certain that s15 psu's blowup and die in the 243-245 volt range.

I will post info on the new protection unit here tomorrow .

but dust humidity and of course room temps are more critical then power exactly 220 volts

in a world of perfection.

the mine would be solar and wind powered at 1 cent a kwatt
dust filter
fan cooled to 25c or 77f
humidity at 35%

stable power to psu at 220 volts
psu supplying a constant correct dc value
psu under a 50-60% load
ac under a constant 75% load
all wires one gauge better than needed.

all of the above at cheap cost.

but world is not perfect.
so all of the above needs to be selected to get best results at best price.

paying 60 dollars to protect one s15 psu is at best an okay choice

I rather pay 60 dollars to keep 5 s15's at a good temperature range
or pay 60 dollars to manage the dust for 10 s15's
or pay 60 dollars to manage the humidity for 3 s15's

I think the OP's question is valid.  The topic interested me after hearing possible problems with the S15 power supplies requiring stable 220 voltage.  I keep checking for that vary reason after Phil started looking into:


If the new units need to run @ 220  I would need more info before purchasing a 7nm Antminer with my input of 248-252v

Not to jack this thread but I have not yet run more than a test batch of either. We are waiting on our 40 mw expansion to be up and running before we purchase any large orders. So far the S/T15 series from bitmain as well as the M10S have been ROCK solid and even slightly out performing their numbers. The Innosilicon units I am much less enthused about as they consistanly run 1-2TH under spec at full power draw.

dust and humidity are more damaging then voltage issues.

I meant to ask  are you running a lot of s15's or mostly m10's

We had the one report of some dead s15 psu's running in the 240-245 volt range

2 maybe 3 on this site.
I am mostly m10's myself no psu issues.

I know you run lots of gear I wondered if you have tested enough s15's to form an opinion on them.

The suggestion is dont waste the money because it will do nothing for you.

The PSU IS the voltage regulator for the miner. That is why they have a variable input range but always output a stable voltage. Whether you feed a PSU 210v or 240v, the DC output will still be the same.

You should double and triple check what you hear, especially on the internet, because whoever told you that is pretty clueless.

What kills ASICs is poor environmental management 99 times out of 100

Hello. I am planning to start my own farms using ASICS. I am looking for any suggestions on using voltage stabilizers/regulators since I’ve heard that one of the main reasons in degrading ASICS is voltage transient. Any suggestions on it? Is it really worth it?
