KPA1500 and Power Line Anomaly
Locked
 
|
This morning I experienced an AC power line dropout of less than a second. Lights in the house blinked very briefly. My UPS recorded the event, but duration was not long enough to reset the digital clocks in my house. The KPA1500 power supply was plugged in, and the amplifier was turned off. The power line dropout caused the KPA1500 amp to turn itself on, in the standby mode. Any others ever experience this?

Of course, you are right! I have that on all my 115 v gear (including the K3) but not on the KPA1500 PS, which is just plugged in to the 220 v outlet. A lesson learned…

Thus the reason why a master "kill switch" feeding all outlets in the radio shack is a good idea. Or at least unplugging the power supply(ies) when not in use. More rigs (and computers) are damaged by power line surges and transients than by lightning events. 73, Kent K9ZTV On 12/3/2018 8:28 AM, Ed G wrote: This morning I experienced an AC power line dropout of less than a second.

I’ve had power drop-outs two or three times. Haven’t had the KPA-1500 or the power supply turn on after any of them. Could you have caught a surge?

Anything is possible. Next time we have a power drop will check it again. The way I know it happened is I saw on the remote screen the amp was now on. The amp is in the basement. That is why the fans are so quiet 😊
