It is certainly part of the advanced pre-heating circuit that keeps the backlight always on |O (My only real pet peeve with this otherwise marvelous bit of kit) |
| TheSteve:
Mine is always silent except if I run a heat gun on the same circuit. I get the same buzz/hum on some other HPAK supplies as well with the heat gun. |
| Fred27:
It doesn't just hum when plugged in, it draws about 10W on standby. It really does need a proper physical power switch. |

Have 12A, ch2 and ch3 can track with each other, but can't figure out how to configure dual channel with +/- output. |
