Hi,

I try to explain very briefly:
VAC = Voltage, Alternating Current You can find this voltage in wall-outlets, the well-known mains voltage with 50 or 60Hz frequency or a Voltage coming from a mains' transformer secondary winding (opposite of VDC which comes from batteries or rectified and filtered supplies)
VA = Volt x Amper, power when the voltage and the current is not in phase
WATT = effective power
VCT = Voltage on a Center-Tapped transformer winding, see for instance data sheet at URL h**p://www.allelectronics.com/pdf/58.pdf (replace * with t)
If you consult electronics dictionaries/textbooks, you may find further explanation on the above terms.

regards, unkarc
