A prototype Wren with a new and improved WrenDAQ. This time Pine Ridge Products sent us a Wren for fitup and testing.

Fully connectorized for easy removal. In this picture the power wiring harness is in place, but the temperature and anemometer harness is not. The big white connector provides DC for voltage and current measurement and AC for frequency measurement. When the WrenDAQ2 isn't installed there is a bypass plug.

Bottom view of the Wren and WrenDAQ2. Once again, the sensor wiring harness is not in place. the wiring and antennas are directly in line with the mast to reduce turbulence and to shield the WrenDAQ2 from airborne debris. The WrenDAQ is mounted with a CNC milled 3/16" thick aluminum plate.

WrenDAQ installed on it's namesake, the Wren.

This is the same WrenDAQ in the first picture. Wind generator development is a brutal business!

The next case will probably be billet or cast aluminum. This one was polycarbonate...
