UPS Systems for Metro and Rail Systems
Metro and rail systems depend on continuous electrical power for safe and coordinated transportation. Power failures or voltage fluctuations can affect signalling, station operations, passenger information and communication between control centres and vehicles.
UPS systems provide immediate backup power to critical equipment until mains power returns or an alternative power source becomes active. They also protect sensitive electronic devices against electrical disturbances and support uninterrupted system operation.
Systems Protected by UPS in Metro and Rail Applications
- Signalling and traffic control systems
- Station control centres
- Passenger information systems
- Communication and radio equipment
- Ticketing and turnstile systems
- Camera and security systems
- Emergency lighting and warning systems
- Network and data communication devices
The required UPS capacity should be determined according to load priority, total power demand and required backup time. Systems directly related to passenger safety and traffic management should be supported by separately planned and, where necessary, redundant power solutions.
Altay Enerji evaluates the electrical infrastructure and operating requirements of metro and rail facilities to determine a suitable UPS solution. A correctly designed system helps maintain safe transportation and reduce disruptions caused by power problems.
