Product Details

The Arco Zeus A275L is the highest power output alternator in its size and class, engineered for high energy production. This model features a 4" J180 saddle-style dual foot mounting configuration with isolated ground and terminal block, delivering exceptional 12-volt charging performance with SAE J1171 certification and proudly made in the USA.

Performance Specifications:

  • Maximum output of 311 amps at 9,000 RPM (cold)
  • Sustained cruising output of 227 amps at 6,000 RPM (hot)
  • Sustained idle output of 198 amps at 3,000 RPM (hot)
  • Reduces the need for a generator by creating additional power with your engine

Advanced Cooling Technology:

  • E-Coat/Cerakote advanced coating absorbs less heat, keeping the alternator cooler for sustained amperage output
  • Runs 8-20% cooler than competitors, enabling more amperage for sustained periods
  • Heat-shedding coatings, exterior-mounted rectifier, dual cooling fans, and highest-quality OEM parts
  • Maximum continuous operating temperature of 110°C (230°F)

Key Features:

  • Suitable for marine, RV, military, and commercial applications
  • Rapidly charges large battery banks
  • 16-pole rotor with 138mm stator size for maximum efficiency
  • 6 positive and 6 negative 50A rated avalanche diodes
  • External only regulation with terminal block and P-Type harness included; requires external regulator such as ARCO Zeus Bluetooth alternator regulator
  • Standard 49K6 pulley (6-groove, 49mm) with 17mm diameter shaft
  • Replaces most Volvo Penta alternators using 4" J180 saddle-style mount

The Zeus A275L is optimized for performance at idle speeds, making it ideal for vessels and vehicles that demand high amperage output even at lower engine RPMs. Pair with an ARCO Zeus Bluetooth alternator regulator for maximum performance or lithium battery charging capabilities.
