Description

The compact and powerful MGC2000 generator control system features a
unique, simple-to-install and setup design and enhanced operation.
The control method for the MGC2000 may be specified for using either the
AS3000 Autostart automatic controller or the 518APH electrically tripped
annunciator method. 
The system is available in 2 basic configurations: 

1. MGC2000 

features mechanical gages: 

MGC2000-A

Automatic Control:

with AS3000 Generator Controller.

MGC2000-M

Manual Control:

with 518APH annunciator control.

Both configurations include standard AC voltmeter, AC ammeter, and
frequency meter. Available for single phase, standard three phase, and three
phase re-configutable generators.

2. MGC2000E

features electric gages: 

MGC2000E-A

Automatic Control:

with AS3000 Generator Controller.

MGC2000E-M

Manual Control:

with 518APH annunciator control.

Both configurations include standard AC voltmeter, AC ammeter, and
frequency meter. Available for single phase, standard three phase, and three
phase re-configutable generators.
