Hello,

I have a 270 amp SD 4900 series 270 amp, with external regulation.

questions.

How many poles, and what would the hz be at 6000rpm and 2000rpm alternator speed?

Do you have a NM Torque Curve for the alternator?

I have the output curves, and in the past some of your output curves also showed the NM Torque curve.

Last question, Is the data for the output and torque curve available in data base format? As I would like to be able to plot the curves, along with the torque/HP curve of the diesel engine that it will be installed to.

Regards,

Lloyd
