Description
The STC series three-phase synchronous alternator can be used in the town, village, construction site, mountainous area and pasture as a power source for illumination. It can also serve as a standby power source for emergency.

Optimum efficiency will be obtained with the working temperature ranging from -15℃ to 40℃ and the attitude below 1000 meters.

Features
1. Our three-phase synchronous alternator has a rated voltage of 400V and a phase voltage of 230V with its three-phase four-wire design. Its frequency is 50Hz and the power factor is 0.8 (lag). We can also provide alternators with the rated frequency of 60Hz and other voltages according to the demands of clients.

STC Series Three-phase Synchronous Alternator

2. Adopting a drip-proof structure, rotating magnetic field and harmonic excitation system, our synchronous AC generator is easy to operate and maintain.

3. This power generation equipment can be directly connected with the prime power via a V-belt. It can provide optimum constant voltage with the voltage regulation rate of 3%, load change of 0 to 100%, and the power factor from 1.0 to 0.8.

4. When the load changes suddenly, our three-phase synchronous alternator can return to the normal working statement quickly without any starting equipment.
