A.C. Power Requirements

Postby bdring » Wed Apr 13, 2011 2:36 am

How much A.C. power does a 40W laser use.

I have never measured mine, but I can give a rough estimate. The tubes are 10%-20% efficient so that would be 400 watts. Most people use a 100-150W 24V power supply. So that put a system at full continuous power at about 550W.

You also need to account for the assist air (mine is 60W) and the exhaust blower (mine is huge at 1/3 hp or 250w). I don't know what a PC and monitor are, but modern ones are probably less than 350watts if you use an LCD.
