>From the technical manual typical draw off of AC mainis about 200 milliamps. That yields 
a power draw of about 24 watts on average. Also from the schematic based on the 
current limit resistor value and the max current spec for the pass transistor about 2.5 
amps draw off the +5 VDC line is safe maximum. That would yield about 13 to 15 watts.
