OK, I picked up a Kill-A-Watt device from ebay and it was just delivered today. For those not in the know, a Kill-A-Watt unit plugs in to a wall socket...it has a digital read out and you plug things in to it. It has the ability to report voltage, watt consumption, amperage consumption, and a few other things. I went out to the game room and used the device to determine the power consumption of my different arcade cabinets. The following numbers represent the MAXIMUM value that came up on the read out...our cabinets don't consume electricity at exactly the same rate like a light bulb...theres usually a 2 to 5 or 6 watt fluctuation. To determine the accuracy of the device I first plugged a 15w florescent lamp in to it. It read 15w. I next plugged a 60w lamp in to it. It read 60w but would flash to 61w every once in a while. It seems to be pretty accurate.
Here are my results:
Asteroids Deluxe - 145 watts
Asteroids - 149 watts
Star Wars - 238 watts
Tempest - 239 watts
Marvel vs Street Fighter (25" monitor) - 125 watts
Nintendo VS Unisystem - 92 watts
Space Invaders - 127 watts
Multipede (60-in-1 Board) - 95 watts
Double Donkey Kong (Arcadeshop Multigame) - 89 watts
Horizontal MAME (25" monitor) - 210 watts
Vertical MAME (19" monitor) - 205 watts
Cocktail MAME/Juke (15" PC monitor + stereo amp) - 235 watts
Now, as for amperage, can someone explain why sometimes I got a readings like:
Space Invaders 127 watts & 1.27 amps
Marvel vs Street Fighter 125 watts & 1.55 amps
I guess I am not up on electricity enough...because I thought if the wattage increase the amperage increase as long as your plugged in the same 120v outlet?
