Topic: Help with choosing a UPS / power conditioning setup for 4xAvalon V1 machines? - page 2. (Read 2975 times)

What about voltage under run protection for those who don't have first world grids?

Do you think insufficient voltage/power would/could damage the units?

Normally people (here) would use only an auto voltage regulator.. But ive been through 4 motherboards in 6 years (with high end APC units for power conditioning/ups/avr).. So it's not really working out well.. At the same time, I've had a server in a near by datacenter for 2-3 years now without a single hitch, reboot, or issue.

The transformers here are shared. I wonder if I should fork out the 1000$ to get them to install a dedicated transformer for my house? Most houses nearby don't even have refrigerators, the transformer now is pretty much dedicated.

Wondering if I should also just get some sort of enterprise level power conditioning for my house. Any recommendations?

1000w psu was used in this application

No. It is not.

Again, please see the american version.. http://www.amazon.com/Tripp-Lite-APS1250-Inverter-Charger/dp/B0007NOUBA/ref=pd_sim_sbs_e_1

Hold on there, so if we want to expand to 4 bays we won't be able to use the stock PSU? That kind of makes the "hidden feature" pointless, doesn't it? Please forgive me if this has been addressed.

I'd like to know if a 650W was used for BF's unit. If so, great, nevermind. If not, OMGWTFBBQ.

I believe this is online/double-conversion (AC->DC - DC->AC) inverter, so it have fully independent input and output.
As for 230V, yes, this appropriate for my location.

Please note that this device simply dumps the utility line voltage onto your Avalon when utility line power is available. It is not a "UPS" in the sense most people understand it. It is simply a battery charger and a transfer switch. It provides no isolation and likely inadequate surge suppression.

Please keep in mind that you get what you pay for with power applications. The most important thing is to make sure you know what you are getting (please see reviews for the American Version).

Also it is designed for 50Hz 230V operation. Is this appropriate where you live?

A UPS will increase your power draw as well.  It is probably not worth buying UPS for bitcoin mining.

the units are 620W max, I mean the power supply shipped it's a 650 Antec, so buy UPS accordingly.

With all those prices I would say: go for a normal gas/diesel driven generator and plug it over manually if needed. in 4 months you wont need the usv anymore... just my guess

you might even consider mining only with this generator in the beginning

I wouldn't do a UPS for a bitcoin miner or any other power using application. Its kind of like putting a drill press on a UPS so your factory can keep operating and you won't "lose money."

Here are the levels of protection are called and the terms you should use in specifying them. You need to know what you are doing so you are not robbed, for example buying a Monster Line Conditioner.

1) MOV protection - this is probably good enough for the Avalon device. Make sure you pay attention to the joule rating of the MOV and that the device has some indication that it has "blown."
2) Ferroresonant Transformer - In industrial settings where MTBF is a concern they will use something like a Sola Hevi-Duty Ferroresonant Transformer. You can probably find this as "leftovers" from an industrial application on ebay for pretty cheap.  Here is a product which can run 8 Avalons for only 5,000$. This is a bargain compared to the installation price of a UPS for an Avalon.
3) Complete electrical isolation - I guess you could install a bank of lead acid batteries and an inverter as you would in an application where people's lives would be in danger, there is a risk of massive financial losses, or you have made guarantees to customers they will not lose service. Hashing bitcoins doesn't really fit into any of those categories AFAIK.

Looking on this unit: http://www.amazon.com/APSX1250-Inverter-Charger-12VDC-230VAC-outlet/dp/B000BCEOIQ

I prematurely locked this thread and received a PM with some more useful info for future Avalon ASIC owners:


Thanks, bittenbob.

You want an UPS that can handle 4 of those Avalon monsters at once? Then "APC Matrix 5000VA/5KVA UPS" is the way to go. Or you could just buy 4 separate 1400VA UPSs.  If you want a rackmount solution then you want something like this: APC SmartUPS 1400VA ((SU1400RMXL3U).

The title says it all, based on power consumption/load numbers being reported from the field, can anyone suggest a solution?
