Applications
・ Submarine power system:The German Type 209 submarine (1,200-ton class) is equipped with four 12V493AZ80 diesel engines, along with four sets of lead-acid batteries (with a total capacity of 187.2 tons) and dual armature propulsion motors. Its surface range is 8,000 nautical miles (8 knots), and its underwater range is 400 nautical miles (4 knots).
・ Land-based emergency power supply:It can provide a continuous power of 551kW in a 50Hz power grid, with an overload capacity of 110% (for 1 hour), and is suitable for backup power supply in nuclear power plants.
