Description
The generator is brushless with PMG excitation; the digital regulator DM110 is fitted as standard and the DECS150 is optional. The voltage regulation accuracy is ±0.25 % at 4 % engine governor droop. The insulation is class H (data for class F, 105/40 °C, are also available), the protection is IP23 and the cooling is CoreCooling. The no-load voltage waveform distortion is less than 1.5 %, and the telephone influence factor TIF is < 50. The data conform to IEC 60034, BS5000-3, ISO 8528-3, VDE 0530, NEMA MG1-32, CSA C22.2-100 and AS 60034, radio interference suppression is to BS EN 61000-6-2 and 61000-6-4, and the quality system is BS EN ISO 9001. Options include an SAE 0 adaptor, an RTD on each bearing, controlled short circuit and anti-condensation heaters.
How to choose
For 380–415 V this is the most powerful low-voltage frame size of the S-Range, and lower outputs are covered by the S5 and S6 (up to 1695 kVA at 60 Hz). The medium- and high-voltage versions S9M1D and S9H1D are covered in a separate item. All data are given for four poles at 1500/1800 rpm.
