 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
  • Military Vehicles
  • 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
D-star Alternators

This line of D-star alternators currently marks to top-end for air-cooled units! An amazing 520 Amps at 14V or 550Amps at 28V equalling in up to 15.4 kilowatts.

Unique features include:

  • isolated positive and negative terminal, ideal for daisy-chaining or maritime applications
  • parallel operation of multiple alternators with no additional effort possible
  • optional air intake filter or additional flange to get cool, clean air for cooling.
  • external, adjustable regulator to cope with all electrical systems and battery types including LiIon-batteries (optional)
  • High output even at low RPM
  • Temperature range up to 110°C / 125°C
  • sense input allows for cable loss compensation to deliver power at the point-of-load (think of electrical winches!)
  • brushless design
