Ok Chaps
I have taken some measurements by hacking into one leg of one bank and inserting a R47 resistor.
Running the unit & measuring the difference in voltage on a scope across either side of the resistor the results are as follows
Eco mode 2 (hi power save) I get 50% duty and 400mV which I make to be 850mA
Eco mode 1 (medium power save) I get 50% duty and 680mV which I make to be a whopping 1.4A!!
Eco off mode gives the same current but ups the duty to 66%
I ran this test last night and again this morn to be clear I was getting readings that agreed.
