[RE-wrenches] DR Power curve

The curve in the old flyer climbs rapidly showing about 93 % peak efficiency
at approx 150 to 350 watts, then straight lining it down through/to approx
83% at 1500 watts. It does not start on the chart at 0 watts though which is
interesting, it starts climbing at 80% efficiency from the 25 watt line.  So
at 10 watts (interpolating backwards) you must be at approx 33% efficiency!
Hope this helps

Does anyone have a power curve for a DR 2412 inverter?

 

I need to show a customer that it is not 94% effecient with a 10 watt ac led
pluged into it alone. 

I am betting that it needs 500 watts to get into the 75 or 80% range. 

 

Thanks,

Bob
