HDD GURU FORUMS

Primitive question please,
where to find the "Power Monitor" in PC-3K.
As per ACE-Lab Tutorial one needs to double click on the 3v/5v green lights.
I did, unfortunately nothing popped up!!

Only available on express & portable.

In order to monitor the current, there would need to be a current monitor IC or ADC. All I see in the power section are 4 ordinary load switches (TPS2590).

really, never knew this!
thanks by the way

No fzabkar, I'm speaking about current monitoring window. It's pc-3k udma and everything seems fine with it as it provide both 3v and 5v as it's shown in new attached image.

@Recover-IT, there is no current monitoring circuitry that I can see. As for 5V and 3V, I think you meant 5V and 12V. In any case, this just means that PC3K has turned on each rail via the two load switches that I mentioned previously. Pin #16 is the Enable input.

I can't see how PC3K can sense the actual voltages -- there doesn't appear to be any ADC circuitry for this either. The load switch has a Fault output on pin #15. PC3K could sense this pin to determine whether either rail has shut down.

Here are photos of the PC-3000 Express Intelligent Power Supply Unit:

There are 8 load switches. I expect that these have a current monitor output which is monitored by the main QFP IC and transmitted to the Spartan-6 FPGA. UDMA has nothing like this.

Hi fzabkar
Thanks for your replay, however I'm speaking on the Software lever and not hardware.
As Lardman mentioned, this fonction is not supported in PC-3000 UDMA. Only in protable and express.

Yes, I understand. I'm just confirming that there is no support in your PC3K hardware for a power monitor.

ic! Thanx by the way
