Battery-free supply chosen in Mexico

The Astronic No Break uninterruptible power supply system has been chosen over battery supported systems by the Ministry of Transportation in Mexico for safeguarding 24-hour illumination in three new high-speed road tunnels, 300 to 1,000 feet long, from Mexico City to Veracruz. Six 200 kVA and two 50 kVA battery-free systems are in operation for unlimited continuity of rotary-generated conditioned power integrating fail-safe kinetic flywheel energy and battery-free backup diesel generators.
