MITSUBISHI MGS SERIES
MGS SERIES AC GENERATOR MODEL: MG-7PF
DIESEL GENERATOR SET
MGS2500B
T ype & Design
MGS original design, single bearing, 4 pole, screen protected, selfexciting, self regulating and brushless with fully
connected damper windings, salient pole rotors, A.C. exciter and rotating rectifier unit. Direct coupled to engine and
regreaseable bearing, direct driv e centrifu gal blower.
Winding Sy s t e m
Standar d 6 wire winding provides 3 p ha se v ol t ag e. All windings are i mpre gnat ed in vacuum pressure i mpre gnat ed with a
special polyester resin.
Voltage Regulator
Fully sealed, 3 phase RMS sensing AVR with built-in protection against sustained over-excitation. This de-excites the
generator after a minimum of 5 seconds.
Permanent Magnet Generator (PMG)
Electrically isolated from the main alternator stator windings powers AVR - sustaining approx. 250~300% of short circuit
current at the AC generator output terminals for not more than 10 seconds by means of excitation voltage via AVR
Electrical Design
In accordance with BS5000 Part 3, VDE0530, UTE51100, NEMA MG1-22, CEMA, IEC34-1, CSA22.2, AS1359 and
JEC2100.
