STC generators are suitable for three-phase AC power supply for lighting and power in villages, towns, construction sites, mountainous areas and pastoral areas, etc. They can also be used as standby power supply for emergency purposes. The generator is of anti-dripping field type, adopting star connection with neutral point, rated line voltage is 400V, phase voltage is 230V, frequency is 50H, power factor is 0.8 (lagging). Generators of 60 Hz and other voltages are also available on request. The generator can be directly coupled to the prime mover or connected by a v-belt, and is rated for continuous operation in forward and reverse rotation. When the rotational speed of the prime mover changes by 3%, the load changes from 0100%. cos 1.0- 0.8 Fan circle, its constant voltage performance is excellent, at the same time, without any starting device can be directly started 0.7 times the capacity of the unloaded squirrel cage asynchronous motor.
