KPA500 Main Power - ON 24/7/365?

Is there any harm in leaving the KPA500 rear MAIN Power Switch ‘ON', 24/7/365? (not the front panel power button).

I have done that with my KPA500 at the home station with no problem, but wondered about doing it at the remote site? I can operate the front panel “ON” button and “OPER/STBY” switch remotely so the amp is not running full-time, just the internal power supply.

73,
Jack W9JH

If you leave it "on," the power supply is energized. A surge on the
line could fry the unit. It happened to me with a Yaesu Quadra.

Hi John,
Both my KPA500 and KPA1500 are on a shelf in the basement, literally right under my feet. The last time I shut them off was when I went to KP2M last February.
If the power switch isn't on I can't tun them on from Elecraft's remote software.
N2TK, Tony

I have been looking into remote switches. While I have not settled on anything, I am looking at remote controlled high power handling relays. Not saying that they are needed in this situation, but they are an option. Then you could leave the power switches on, close the relay, and use remote software to turn them on. If you are remote already, you prolly have the capability.

Hi Jack,
I've had both my KAT500 and KPA500 powered on 24/7 for the last several
years, as I operate them remotely from my second home in Texas. The
KPA500's AC power is connected through a dedicated line, surge protector
and battery backup. The KAT500, which is DC powered, is connected to an
Astron RS-35M, which is on a dedicated line, surge protector and battery
backup.

As Tony, N2TK, stated, they need to be powered on if wanting to run
remotely.

What surge protector are you using?
