evc/epc Controller
With SAE J1939 Interface
Dual Output With Over Speed Protection
It works with dual fixed displacement pumps and switches valves ON or OFF according to the measured RPM.

The measured engine RPM can be from the
alternator ‘R’ terminal, PPU, or SAE J1939.

BOTH outputs are ON when below ‘A’ setting.
 When the measured RPM ≥ Set-point A RPM,
coil A ramps down to minimum current.
 When the measured RPM ≥ Set-point B RPM,
coil B ramps down to minimum current
NOTE: with Ramps set to minimum times, the
outputs will drive ON/OFF valves
