I just purchased two of these. I like that they run on 110v and my house uses electric heat. My wife lets me use them since they are quiet.
Question on power. I understand the default frequency is 600 and powered via a 1,000 watt PSU. However, when plugged into a Kill-A-Watt, in order to get it under 1,000 watts, I need to set the frequency to 450 which keeps it around 900 watts (for some safety).
How can the default be 600 when it pulls in excesses of 1,000 watts when using the default frequency?
