Marathon-Type 314 Series Brushless Alternator Heads 6.5-120 kW - Copper Wound, IP23, Class H, SX460 AVR

Brushless alternator heads from the Fujian Marathon motor factory - the Chinese licensee-side production of the classic Marathon 314 series. Wound with copper wire and regulated by an SX460/SX440/AS440 class AVR to within +/-1.0%, these heads cover 6.5 kW to 1200 kW across the range, with single-phase and three-phase connection options and voltage arrangements from 208/120 V to 480/277 V. The factory publishes its own comparison table against unbranded rivals: copper winding, 24-hour test before dispatch and a two-year warranty versus aluminium-wire, untested or refurbished units from trading companies. For buyers replacing a Marathon or Stamford-format head, the 314 series frame is the reference design - as always, confirm flange and drive details with us before ordering.
