Alternatives to Power-Z?

[R7027]

Hello everyone!

I am looking for an alternative to the Power-Z USB power meter, like the model KM001. Are there no alternatives to this? Other than other models from the same company? This is a very popular meter that repair pros use.

I have a very simple and inexpensive USB power meter. I think it costed around 20 - 30 USD. I'm looking to upgrade it to one that has the logging and graphing functions like the one I mentioned above. Something in the same price range of 80 - 100 USD. Any suggestions?

I actually have a DC power supply that has a USB port and Modbus support, so I can control it from the computer by a COM port over USB, and I can get the power graphing function this way. But it comes with a crappy software that makes it difficult to use. Would it be possible to buy a compatible third party software? Using the DC power supply would be ideal for logging and graphing voltage and current, because you're not locked in to USB voltage and current levels.

Thanks in advance!
