Hi all,
I am upgrading my amplifier, and I would like to verify my understanding of power consumption as reported in user documentation. If the power consumption is listed in terms of wattage, I am taking that to mean the RMS value. However, my surround processor lists it in terms of current, and am converting it to the VA value, dividing by 2**(1/2) to get the RMS value. My question is, can I automatically assume that if the power consumption is listed in wattage, it is the RMS value, and if it is in terms of current, I need to perform the above conversion before I can compare "apples to apples"? I am trying to determine the additional load my UPS will have to take on (and avoid exceeding its capacity) TIA!
Peace... Derek
