GENERATOR FEATURES
Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with
BS5514, ISO3046 and DIN6271). Prime (Unlimited Running Time): Applicable for supplying electric power in lieu of commercially purchased power. Prime power is the maximum power available at
variable load. A 10% overload capacity is available for 1 hour in 12 hours. (All ratings in accordance with BS5514, ISO3046, ISO8528 and DIN6271).
SG010 / SG015
■
Four pole, revolving field generator, directly connected to the engine
shaft through a heavy-duty, flexible disc for permanent alignment.
■
Generator meets the temperature rise standards for class "F"
insulation as defined by NEMA MG1-32.6.
■
All prototype models have passed a three-phase symmetrical short
circuit test to assure system protection and reliability.
■
All prototype models are tested for motor starting ability by
measuring the instantaneous voltage dip with a waveform data
acquisition system.
■
All models utilize an advanced wire harness design for reliable
interconnection within the circuitry.
■
Magnetic circuit, including skewed stator design, provides a minimal
level of waveform distortion and an electromagnetic interference
level which meets accepted requirements for standard AM radio, TV,
and marine radio telephone applications.
■
Voltage waveform deviation, total harmonic content of the AC
waveform, and T.I.F. (Telephone Influence Factor) have been
evaluated to acceptable standards in accordance with NEMA
MG1-32.
■
Alternator is self-ventilated and drip-proof constructed.
■
Fully life-tested protective systems, including "field circuit and
thermal overload protection" and optional main-line circuit breakers
capable of handling full output capacity.
■
System Torsional acceptability confirmed during Prototype Testing.
