Auxiliary Power Supply System
Fuji Electric provides a high efficiency and economical auxiliary power supply system (APS) for railcars used in public transportation. The APS was designed to provide less frequent stops and easier maintenance.
Fuji provides the best solution for every customer's operating service requirements.
Utility frequency (50/60Hz) isolation transformer system
Features
- High efficiency
That a small number of parts in a simple circuit
configuration, has achieved high efficiency. - High reliability
That the control is simple and the number of components
is small, has high reliability. - Saving maintenance
It requires almost no maintenance
Medium frequency isolation transformer system
Features
- By increasing the frequency of the isolation transformer, it becomes about one-tenth the size and weight of the inductor and the transformer, and has achieved a reduction in box size and weight.
Auxiliary power unit of Fuji Electric has been used in any environment in the world.
