-Sensing voltage: : 100/110Vac 50Hz, 120/130Vac 60Hz, 380/420Vac 50Hz, 430/450Vac 60Hz
-Power supply: (maximum 180Vac 50/60Hz), Shunt+Booster = power transformers, AREP = auxiliary windings, PMG = external generator
-Field output: 12 Amperes nominal, 24Amp maximum during 10s on 6Ωminimum
- Accuracy: +/-0,5% of the means of the three phases on linear load and without droop
- Voltage setting range: +/-10% of the nominal voltage by means of external optional potentiometer, according to alternator capability.
- Droop setting range: - 7% of the nominal voltage at cosØ =0
- Under-frequency protection: Adjustable threshold and slope from V/Hz to 2V/Hz
- Field ceiling: 110% of If nominal permanently, unlocked in case of voltage decrease
- Protection: Heat sink overheating, exciter short-circuit
- Alarm output: Heat sink overheating, too much ceiling unlocked time
- Environment: Maximum ambient temperature -10°C to +50°C, Fitting in control panel without excessive vibrations
