Digital Governors
The SDG-500 Series (Smart Digital Governor) is a solid state microprocessor based speed control unit that off ers precise (+/- 0.25%)
isochronous speed control with fast response to transient load changes. Designed for high reliability and ruggedly built, the
SDG-500 Series is hard po� ed to withstand the harsh engine environment and can be mounted directly in the engine compartment.
The SDG-500 Series has several built in confi gurable features: three fi xed and variable speed with correla� ng droop
se� ngs; engine shutdown protec� on; speed ramping from idle to opera� on speed; and start fuel control for lower engine
exhaust emissions.
The factory standard SDG-500 Series is pre-programmed to OEM’s specifi ca� ons. The SDG-510 and SDG-511 have no end user
modifi able se� ngs. The SDG-512 and SDG-513 are equipped with a single turn gain trim poten� ometer for fi eld adjustments.
If needed, confi gura� on and tuning of the SDG-500 Series can be accomplished by the OEM via GAC’s SmartVU TM confi gura� on
so� ware. The so� ware allows users to save the current confi gura� ons and data to disk or fi le. Saved se� ngs can be u� lized
for confi guring mul� ple units.
