Hi, List,



I'm building a Zenith CH-801 and am planning on using a DeltaHawk diesel

engine.  DeltaHawk uses a 24v starter but the flap and trim motors and the

strobes require a 14v system.  Does anyone know where I can get a 24 to 12v

converter that can provide 5A continuous and 10A intermittent?  I'm averse

to using a tap on the battery string (2 batteries of 12v each) as I've had

really bad experience doing that without an equalizer, and those things are

really heavy.  Suggestions are appreciated!



Thanks



Jim

Jim,

      Although not a general purpose DC-DC converter, but for the common 

trim systems such as the Ray-Allen servo based systems the Safety-Trim 

intelligent controller takes care of this requirement of operating from 28 

Volts but driving servos only rated for 14 volts.  The Safety-Trim servo 

controller as an input voltage range of 10-30 volts and has a maximum output 

voltage of 14 volts.       We've had a few customers chose our product with 

same application of the DeltaHawk diesel and Ray allen trim servos.



-Best regards,

These were recommended to me when I was looking at Deltahawk.

Has Deltahawk given you a delivery date yet?

We had to give up on them after two setback dates.
