1.17 Decision-Makerr 3500 with
Integral Voltage Regulator
The voltage regulator is integral to the controller and
uses a patented hybrid voltage regulator design to
provide 0.5% no-load to full-load regulation using
root-mean-square (RMS) voltage sensing.
The voltage regulator features three-phase sensing and
supports both 12- and 24-volt engine electrical systems.
D The Decision-Makerr 3500 graphical display and
pushbutton/rotary dial provide access to data. A
five-line, 35-characters per line LCD display provides
complete and concise information include gain, ramp
rate, reactive droop, VAR control (P, I, D gains), and
PF control (P, I, D gains).
D The controller supports Modbusr.
