Can I see my used max-watt on my P15?

Hello, I have just bought a Power Plant P15 and as you know you can see how many watts the P15 uses this instant but since I have not connected my P15 to the internet I don’t know what you can see there.
What I’m curious about is if it’s possible to see how high the watts on the P15 has peaked so you can see that: “Aha, my P15 came all the way up to 1244 watt there”?

If it’s possible, I would suggest that you made it so that one could see somewhere how many watts the P15 has used as most since the last time you turned it on.

Hope you’re enjoying the new P15 so far. Yes, when the P15 is hooked up to the network, you are able to see this type of data. However, our servers for this function are currently being worked on and updated so you can’t view this data. I agree, it would be really cool to see this type of data on the screen though. I’ve sent your note to the engineers so they can possibly add it in a new firmware update.

is the Estimate for getting the server back up the end of summer, or end of 2019? Thanks

We’re doing our best to get it ready before the end of 2019.

Is the max wattage used being record by the P15 or the server? The reason I ask is if the server is keeping track of this, it may not be accurate depending on server sample rate. I doubt the server is sampling the P15 usage very quickly which mean it will likely miss those hard hitting transients.

As of right now it is not being recorded, but once global net goes live again, it will. You bring up a very good point. I don’t know to what degree the recording it accurate. If it’s a very brief burst of current, it likely won’t see it with 100% accuracy. It will certainly give us a good idea though.

jamesh, when was it last working?

If I remember right, it was right before we moved to the new building last year so maybe July of 2018? :thinking:

This question would also be mine: are the real max. ultra short termed dynamic peaks visible/measurable within the unit? Some claim those are much higher than the theoretical max. power consumption of an amp which are commonly used for dimensioning the own need of regenerator size. Don’t know if this makes sense.

Ive had regenerators for about 4 years. As far as I am aware, this feature has not worked in that time.

Roughly a year ago sounds correct. It had been a good while.

It is a fun little feature

I don’t think so. Our fellow neighbors over at NIST have the oscilloscopes you would need to catch this resolution, but I’m skeptical us audiophiles need that level of accuracy in our PowerPlants.

Definitely not the accuracy in measuring! I meant if the short peaks of power needs are possibly much higher than the spec of an amp tells the max. power rating.

Sorry but I have been unclear. My main point was, if those measured peak values within the regenerator or official amp specs are any meaningful regarding the real max peaks occurring in practice.

Ah, thanks for clarifying. :slightly_smiling_face:

Absolutely. No question. This is a spec sheet for a transistor.


You can see the continuous is much lower than the pulsed output.

So if someone is dimensioning his regenerator at the limit of the specs in terms of max power consumption of his connected components…is it overpowered within dynamic peaks?

This is a really good point. This is exactly why overhead is a good idea. We suggest the PowerPlants operate at about 80% continuous load max for two reasons. Heat, and overhead. There is protection within the PowerPlants so that we never actually hit the pulsed value (It can cause damage to the unit). To sum it up, there is not going to be dynamic strain if steady operation is </= 80% continuous load and it’s not shutting down during loud passages.

Thanks, makes sense…I just had expected that dynamic peaks rather go above max. continuous load not only by 20 but by 50-200%, but if you say that the unit then would shut and not just cease to deliver, this can’t be I guess.

The reason I doubted this is because a Class A amp with 2x100W usually has the same dynamic capabilities as an AB amp with 2x 1000W, but a very different possible continuous load.

It would be very interesting to get a real max. dynamic peak measurement (without using a regenerator) and compare it to the continuous load.

And it would be interesting if e.g. the IRSV setup can e.g. shut one P20.

I’m darn curious if we could shut down one P20 with the IRS system. I’m sure we could. I certainly don’t need to be in the room while we do it though. I still have a high value for my young ears!

I agree…unless the speaker is very complex in load and therefore very demanding already at human levels, a shut down is probably no matter usually…I just remember I read of a few shut down cases here in the forum with much smaller/normal speakers than the IRS.

My old Kappa 8 I have in my storageroom now goes all the way down to 1 Ohm as worst.
