Rosetta, power consumption
« on: April 16, 2019, 03:48:38 pm »

Just laying out the (all electric) instruments for our new super-lightweight** Me7 glider, which goes on sale this summer.  And was thinking of installing a PAW unit as standard in each one. 

Q.
Could anyone give me the standard (average) power consumption of the new Rosetta, as I hear it has reduced from the original 5w.

** Single seat,  carbon fiber airframe,  32:1 glide, total airframe weight 105kg,  MTOW 240 kg.

Hi Roger

Recommendation is still for a 2.1Amp supply, we recommend Anker, we have found them to be the most reliable

Thx

Certainly need the capable power supply as stated by Lee to cope with surges etc.

Mine (with a Pi3) after boot and running normally has an average current drain of 600mA as measured by one of those USB volt/current devices

Just measured mine at 590 mah, which is in the same ballpark as Vic's report. Just under 3w Average.

Peak wattage is quite a bit higher hence the need for a good supply.
