•  Automatic frequency & phase synchronization (differential frequency meter + synchroscope)
•  Engine parameters: oil pressure, water temperature, speed, and hour meter

MCGSP-Gensys Compact Mains GenSet Panel

The MCGSP-Gensys Compact Mains GenSet Panel is a complete panel solution that takes the CRE Gensys Compact Mains GenSet Controller to a new level. To complement the controller, we’ve added eight (8) 100mA 600VAC fuses for AC wiring, a convenience terminal block for wiring functions (see terminal block exhibit A), an on/off toggle switch, a push/pull red mushroom emergency stop button, and shock mounts. All components are mounted comfortably inside a custom designed metal enclosure with a matte black/fine texture powder coat finish.

This panel facilitates the CRE Gensys Compact Mains GenSet Controller. The Gensys Mains, a switchboard panel mounted version with display, is dedicated to a large variety of standby diesel or gas gensets, offering isolated speed and AVR outputs along with three (3) isolated communication ports: two (2) for CANbus, and one (1) for Ethernet. The controller offers flexibility and time savings due to its simple wiring, diverse feature set, thoughtful engineering and easy programming.
