PX-833 28 volt / 330 amp Alternator

The air-cooled PX-833 upgrades the oil-cooled 50DN, eliminating hazardous waste

PX-833 Hardware Components

The PX-833 uses the existing wiring.

The PX-833 is designed for use with 50VR style regulators.

Mounts in the standard saddle bracket and uses the same pulley as the 50DN.

Tapped holes in the front housing allow for ground cable and/or other connections.

Oil line caps/plugs are supplied to seal off oil lines at the engine block.

After upgrading to the PX-833, common front seal leaks are eliminated.

The best 50DN upgrade available for tough transit bus applications.

PX-833 Benefits Uses similar electrical components as the 50DN, but produces 60 amps more output; 28 volts / 330 amps @ 5,000 RPM. The higher output is based on a superior fan design, optimized cooling slots, higher diode rating & increased heatsink surface area, which improves heat dissipation. High temp bearings and seals maximize performance in high heat environments. No oil or heat transfer between the engine and alternator; no hazardous waste. Alternator life cycle costs are reduced.
