Topic: TotTop Model and House Voltage (3 msgs / 54 lines)
1) From: John Haley
To answer the replies on Variac necessity for the HotTop that I've received
so far. The model is the KN-8828P fully programmable model. I've checked my
voltage several times so far today and found it 119.3V to 120.4V. If it
stays as consistant as this there would be no problem.

You need to test it with the Hottop plugged in and the heater on full power. 
This is the "real" voltage that it sees.  The no load voltage does not mean 
very much, but still steady is better.
Again, the new model Hottops (both B and P models) should not need a Variac 
as they have voltage stabilization built in.

The 119.3V to 120.4V variation  would give a resistive heating variation of
nearly 2%. That's easy to regulate with a temperature controller.
Unfortunately, the equipment builders usually design for the rated nameplate
voltage as a minimum.
A voltage regulator for the electronic section of the roaster would cost a
dollar or so. If the heater were cycling On and Off, the whole machine would
be riding an electric roller coaster.
Not a machine I'd recommend. Of course, if it's a trouble free stable
machine, I'm all rong.
