[RE-wrenches] DR Power curve

[Mark Edmunds]

Hi Bob,

 

I can't find the power curve right off, but the DR like any inverter is
dominated by its tare loss at light load, which is about 8W in this
case, so running a 10W load will not be very efficient on a percentage
basis! The DR hits peak efficiency around 300W output.

 

Cheers,

 

Mark

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
