Saft has engineered the SRM-F3 cell to meet the specific needs of North America’s OEMs and railway operators for reliable onboard backup power. It combines the reliability and long-life of Saft’s Ni-Cd technology with the field proven performance of sintered/PBE construction. The result is an ultra-light and compact cell housed in a transparent flame retardant polysulfone container. SRM-F3 battery systems have been developed to support electrical systems onboard a wide variety of passenger rail transit cars. They deliver reliable, high-energy backup power that ensures: passenger safety and comfort (lighting, door control, ventilation, communication and Wi-Fi systems, etc.) and fail-safe train start-up (pantograph lifting, computer and electronic systems).
