300V DC Power Supply? [RE-wrenches]

[David Blecker]

Jeff,

I share your concerns about fussin with things that ain't broke.  But these 
are WindyBoy's -- and we don't have enough experience with them in field to 
go out untested.  Also, I'm designing a monitoring system with the 
Windy-Boy-Sunny Boy Control Plus that will record the wind speed (from NRG 
#40 anemometers through NRG's wind speed freq to voltage interface devices) 
into the SBC+ analog input channel along with the standard energy 
production data to give us time-series performance curves for the turbine. 
Whew.  That was a mouthful.  Where's my beer?  So, I have to dig in, open 
up the case, and test.  Did I mention the system is being installed as part 
of an MREA workshop?  We need to have our act together to avoid surprises 
and excessive embarrassment.

The C&H Sales link is way cool!
