 High-Power Alternators 
12V/24V High-Power Alternators

Up to 520Amps at 14V or 550Amps at 28V - almost 15,4kW of electrical power!

The units do have isolated outputs enabling you to operate them isolated from the vehicle electrics, as addon to the existenat alternator (in parallel) or as a powerful replacement.


  • Service vehicles with large amount of power required (e.g. to operate compressors or such)
  • Ambulances, Policecars
  • Rallye vehicles (winching, lighting)
  • Motorhomes
  • Motorboats
  • APUs (Auxiliary Power Units) power with diesel, petrol or hydraulic motors
  • and last but not least huge HiFi-installations
