Effect of Brownouts on Mining Equipment?

[murphinator]

It seems to be a little difficult to find information on how brownouts (voltage drops for sustained periods) have affected people who are running on unreliable power.

We have Avalon 851s hooked up to AlphaMiner PSUs, but I cannot find information on what is the recommendation for handling brownouts.

Does anyone have experience with this? Is it required, or do the miners / PSUs have an intelligent way to handle voltage drops without damaging circuitry.

Thanks.

The miners could care less about a brownout, they will run as normal until the PSU cuts off and will restart the the PSU comes back online.

The PSU's are a different story: Running at a very low line voltage (below their nominal rated minimum voltage, usually around 190VAC) puts a lot of stress on their input circuits and will no doubt shorten their life. When the line voltage drops below a certain minimum the PSU *should* shut off but that feature is up to whoever makes the PSU.
