This line of D-star alternators currently marks to top-end for air-cooled units! An amazing 520 Amps at 14V or 600Amps at 28V equalling in up to 16.8 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
