I have a question for P15 people. I have all my gear plugged into a P15. Yet once or twice per year, a fuse blows in one of my devices. Replacing the fuse fixes it. This is probably doe to some spike in electricity due to lightning, electric work in the neighborhood and such. But shouldn’t the P15 prevent component fuses from blowing? Should the power plant not catch the spike before it gets to the components? The power plant fuses never blow themselves.
I’ve had fuses blow due to internal faults. Although unlikely, if the same unit is blowing the fuse that might be a sign. I do not know about the protection characteristics of power plants.
Powerplant is supposed to protect gear from surges: “Owners who have invested in a Power Plant can rest assured their connected equipment will be safe from any power line event such as over voltage, under voltage, surges, spikes and potentially threatening problems”, But for me it doesn’t always do this. I wonder if the plant has to be fully on to provide the protection.
One scenario I encountered is that my dac’s fuse was blown after coming back from a week away. Powerplant was in standby mode all that time. I suspect some power net event happened that week, it gets wild out here with lightning and work on the power lines. Weird. I understand that surge protectors are not perfect in stopping everything.
It happens rarely enough that I am not bothered and replacing the fuse always fixes it. Now I just unplug the Powerplant from the wall when leaving multiple days. Curious if others experience things like this.
So it’s always the DAC that is affected? Any other components impacted? If it’s just the DAC I’d be suspicious of the DAC and not the powerplant. But, stranger things have happened.
My P20 blew my Aurender NH10 Network hub’s fuse TWICE. Immediately, upon switch-on.
The P20 also became excessively hot and shut down with ONLY the Aurender AP20 plugged in, on idle. I’ve posted a thread in the power section on this, but sadly no response.
Subsequently, I’ve tested my P20 with a Meaco 20L dehumidifier connected, pulling around 300 watts / 22% [very close to what my BHK 300’s + BHK Pre was pulling prior]. It worked flawlessly. Then sent it off to a really top-notch technician doing most high-end repairs here in SA - all checked out fine, no leaking caps etc etc. Sold it then with a clear conscience (because that was my concern) for around $2060.
There is very little doubt in my mind that there is at least “some” equipment that “does not like” regenerators (or, at least my P20). I recall way back that switch mode PSU’s used in class D often have a “power factor” that places a higher than usual burden on PSA’s regenerators, but I don’t have enough knowledge to comment. Aurender, specifically, uses Toroidals with the AP20 (that uses the Purifi amp modules).
So something is going on; but so far the words seems mum. Hoping myself to get clarity, though I suppose it does not matter any more since I now use a simple Transparent Powerwave X.
