The kil-a-watt that I have says it should only be used for 100-120v. I want to check my total wattage being used on my 240v items, but I can't seem to find a product that can do that.

Plus, it wouldn't even fit, because my 240v does't use standard plugs, obviously. I have a NEMA 240v twist-lock connected to a PDU.

Thanks!

Get yourself a clamp meter ;)

You mean 240v in two phases right? not the 230v single phase used in most of the world. So you can't use a meter designed for a single phase.

You can try to use only one phase from that connector to power some miners and the second phase with the other miners.

What kind of PDU are you using? Many PDUs have network management features, where you can track current for individual outlets and able to disable them if you exceed max amperage.

Therefore, you don't even need a energy meter like kill-a-watt, as most professional grade PDUs will have inbuilt feature, which are more advanced than consumer grade energy meters.

Yes, its 2 phase. Would a clamp meter work?

I have this PDU
Dell-AP6031-PDU-4-Outlet-200-240V-24A-Power-Distribution-Unit-5T439
Using these PDU Extensions:
HP Proliant Modular PDU Extension Bar HSTNR-PS03 411273-002
And then plug in the PCs using:
IEC 320 NEMA C13 C14 10A 18AWG PDU to CPU AC Power Cords

All bought on eBay.

So, after PDU and extensions its all single phase? where is the problem then?

Kill-a-watt uses the wrong type of plug.
Plus, Kill-a-watt says 100-120v max. 240v is still coming out of the PDU.

Just trying to find a product I can use to accurately measure watts.

You can use a power meter for 240v single phase and some connector adaptors. Kill-a-watt is a trademark.

Is there a specific product that you can link me to?

I am still confused as to exactly what I'm looking for.

I understand Kill-a-watt is a trademarked item. But, I plug it in, I plug in my PC, and it tells me the watts.

When I search for "Power Meter" the first link is to kill-a-watt, which for reasons mentioned, won't work with 240v.

I am not sure about the features of that PDU, but I am planning to use this APC's AP 7841 PDU (http://www.ebay.com/itm/APC-AP7841-Metered-Rack-PDU-24-Outlet-Power-Distribution-Strip-200-208VAC-/302364837712) and it has network management features. So maybe you can consider that for future use with your set-up.

Btw...are you using the 240V Dryer outlet at home to connect this PDU?

I'll check out the PDU.

No, I am using NEMA twist lock. I can't remember the number, but like L6-20R or something like that?

I had a professional electrician install it.

What management features does they 7841 have?

I haven't yet installed it at home. Will do that over the weekend and let you know. Per my IT friends, it is a standard PDU used by Corporations and similar PDUs have an ability to monitor current remotely and offer ability to switch on/off any outlets or restart them, kind of like TPLink HS110 Smart Wifi plug.

This one, the "Floureon"   http://www.ebay.com/itm/US-Plug-Energy-Meter-Watt-Voltage-Electricity-Overload-Monitor-Analyzer-Power-/272556571922?hash=item3f75a33d12

It goes from 110VAC to 270VAC


Comments:

0) I'm guessing this is some sort of universal export model.

1) It's not as robust as a Kill-A-Watt meter

2) You will have to come up with some kind of adapter. The plug is US standard 115VAC. Please be careful. This step will not meet electrical code and I'm not responsible.

3) I don't recommend this unit for continuous operation.

4) The claim is that it goes up to 1800W. I wouldn't operate this device at the max power for more than a few minutes.

5) As a check, I would cross check with a Kill-A-Watt before putting it into service.

6) Practically now what I do is just base any setup power measurements @ 120VAC and then move the miner to 240VAC.

This should work for You:
