Product Details

The Arco Starting & Charging 4502 Zeus is a high-performance 24-volt alternator engineered to deliver exceptional power output for demanding marine applications. This 7kW alternator generates over 3kW (109 amps) at just under 3,000 alternator RPM and nearly 6kW (218 amps) at under 6,000 RPM, making it ideal for rapidly charging large battery banks on marine diesel engines, RVs, and commercial vessels.

Advanced 24V Design:

Unlike competitor alternators that use less efficient 12V rotors, the Arco Zeus features a native 24V rotor and field current for superior efficiency and cooler operation. This design directly extends alternator lifespan while maximizing output across all RPM ranges. The unit is specifically designed for Yanmar Common Rail engines introduced after 2013, including JH-CR, 3JH40, 4JH45, 4JH57, 4JH80, and 4JH110 models.

Key Features:

  • Sustained cruising output of 220 amps at 6,000 RPM (hot, 27.5V)
  • Maximum output of 284 amps at 9,000 RPM (cold, 27.5V)
  • Dual cooling fans with exterior-mounted rectifier for optimal heat dissipation
  • E-Coat/Cerakote heat-shedding finish keeps unit cooler during sustained operation
  • 16-pole rotor with 138mm stator for high energy production
  • External regulation with compatibility for Arco Zeus Bluetooth regulator
  • SAE J1171 certified for quality assurance
  • Optimized performance at idle speeds reduces generator dependency
  • 6 positive and 6 negative 80A rated avalanche diodes
  • Maximum continuous operating temperature: 212°F (100°C)

Technical Specifications:

  • Voltage: 24V with isolated ground (Common Rail compatible)
  • Rated Output: 7kW (7,000 watts)
  • Weight: 15.89 lbs (7.2 kg)
  • Standard Pulley: 49K6 (6-groove, 49mm diameter)
  • Shaft: 17mm diameter, 25mm long, threaded M17 x 1.5
  • Battery Post: M8 thread, side mount
  • Cut-In RPM: 1,962 alternator RPM
  • Maximum Alternator RPM: 19,000
  • Field Type: P-type
  • Frame Size: Large
  • Finish: Black E-coating

What's Included:

  • Zeus 24V 7kW alternator
  • M17 x 1.5 x 24mm mounting nut
