AntMiner S1 voltage tolerance

[tensor]

Is there a power guru here who knows what the acceptable voltage range is for an S1 blade? I have a DC unit that can supply around 450W continuously at 13.8 VDC (it maxes out at 50 A), but I'm not sure if it will work as is since it's above 12V. If not, I'm thinking I can put it in series with a diode that has a 1.8V drop, but I thought I'd ask here for advice first.

Thanks.

Actually, never mind. Turns out my DC supply has an adjustable voltage via an internal trimpot. (Very handy!) If someone has the answer to my question, however, please feel free to post.

And FWIW, dropping the voltage across a diode probably isn't the best idea considering how much power that would waste at such high currents.

if you have a power supply like this

the volts will sag  so the 13.8 may be okay just like that.

   10 percent of 12 volt = 1.2

or 13.2 volts

so set your power supply at 13.2 not 12.


10 percent is a common  safety margin for  over- under volts..

I would believe your gear will sag  from the 13.2 setting to about 12-12.2

Thanks for the reply.

I'm planning to use a linear supply (it's an Astron RS-50A), and I think it will hold 12 VDC pretty well. The only thing I'm not sure about right now is the current... It can do 37A continuously or 50A in short bursts (50% duty over 10 minutes). If I understand the information on the S1 I've seen so far, 30A should be enough, right? I'm just wondering if the lower voltage will let me get a higher continuous current for overclocking...

Overclocked S1 (200gh) draws 15-16 amps per blade or 31-31 amps total at 12Vdc
