and current under load and varies the exciter field either
up or down to keep the generator field at such a value
as to maintain constant alternator output voltage. The
regulated voltage setting can be varied using the voltage
adjust rheostat (R1 ).
On MEP-003A, an ac receptacle (J14 ) is connected through
a protective circuit breaker (CB3) to provide 120 VAC.
