P450 Alternator

Product Features

• 28V, 450A Brushless Alternator

  The Power 450 is a 28V brushless alternator that produces 450A @ 6000 RPM, stabilized at 20°C per SAE J56. The only moving parts inside this brushless alternator are the rotor and the rotor bearings. This simple design has proven to be very durable under the harshest conditions.

• High Performance

  The Power 450 produces an impressive 290A @ engine idle or 2000 RPM, stabilized at 20°C per SAE J56. This strong low end performance will meet the vehicle’s electrical needs and maintain the batteries state of charge to optimize the battery life.

• High Efficiency

  The Power 450’s peak efficiency is 82%. The higher the alternator efficiency means less engine horsepower is required to produce the electrical power, which results in less fuel consumption.

• Isolated Ground

  The Power 450 has an isolated ground. Isolated ground alternators have the alternator chassis electrically isolated from the negative power stud. Isolated ground alternators provide only one return ground path to the alternator, via the ground cable. With only one return ground path, the engine block no longer carries some of the current. This prevents stray current on the engine block, which reduces the electrical noise in the engine grounding circuit.

• Air Cooled

  The Power 450 is an air-cooled alternator. The front mounted cooling fan draws in air from the rear of the alternator. The unique internal design allows for very efficient air flow and cooling to optimize performance and alternator life.

• 4″ Air Inlet Duct

  The Power 450 has a 4″ air inlet duct on the rear of the alternator. This enable the end user to attach 4″ diameter piping to the alternator and route the piping to a cooler location. Ingesting cooler air significantly prolongs the alternator life. EMP offers a full line of accessories and engineering assistance on the air intake system.

• Cradle Mount Alternator

  The Power 450 is a cradle mount alternator intended as a perfect drop in replacement for the Delco 50DN.

• Extended-Life Bearings

  The Power 450 has extended-life bearings with proprietary, premium bearing materials to provide optimum life under the most severe applications.  This allows for change intervals of a minimum 17.500 hours or 3.5 years.

• Electrical Noise Suppression

  The Power 450 has an optional integrated noise suppression feature to filter the AC noise from the DC circuit, which provides cleaner electrical power to the vehicle.

• Corrosion Resistant

  The Power 450 has been designed with proprietary cast aluminum alloys to prevent corrosion.
