Newmar PC-25 Power Conditioner Noise Filter

The Newmar PC-25 Power Conditioner Noise Filter eliminates electrical interference that degrades vehicle and marine electronics performance. Alternators, ignition systems, and auxiliary motors generate high-frequency noise that corrupts radio signals, GPS accuracy, and communication equipment audio clarity. This compact 1 lb conditioner addresses the root cause of static, crackling, and signal loss that frustrate drivers and technicians upgrading electrical systems or troubleshooting chronic electronic interference issues.

The PC-25 works by filtering unwanted electromagnetic noise from the vehicle's power distribution network before it reaches sensitive receivers and entertainment systems. Newmar Power's design incorporates ferrite core filtering technology that attenuates high-frequency interference across multiple bands without compromising charging system output or accessory power delivery. The unit mounts directly in-line with primary power circuits, providing passive noise suppression that requires no external power source and introduces minimal voltage drop—critical for maintaining optimal alternator regulation and battery charge rates in demanding electrical environments.

Technicians installing aftermarket audio systems, dual-battery setups, winches, or auxiliary lighting benefit most from the PC-25, as these modifications amplify electrical noise if not properly conditioned. Marine applications—particularly diesel engines with high-output alternators—rely on this filter to maintain VHF radio clarity and navigation system integrity. Installation integrates seamlessly with existing 12V or 24V automotive and marine electrical systems without requiring circuit modifications, making it an essential addition to any comprehensive electrical upgrade or noise remediation project.
