Struggling with crackling audio, flickering screens, or garbled signals in your RV, boat, or off-grid setup? The Newmar PC-25 steps in as your go-to DC power conditioner, tackling electrical noise right at the source so your electronics perform flawlessly. Whether it's alternator whine bleeding into your marine VHF radio or motor hum disrupting your RV's navigation system, this rugged filter delivers clean power where it counts.

Why Electrical Noise Ruins Your Setup—and How the PC-25 Fixes It

Modern vehicles and vessels pack more electronics than ever: stereos, radars, chartplotters, and inverters all demand pristine DC power. But everyday culprits like alternators, ignition coils, and pumps generate high-frequency interference that travels through your wiring. The result? Popping static on speakers, snowy video feeds, or unreliable GPS readings during critical moments.

The Newmar PC-25 shines by suppressing this noise across a broad spectrum—from audio frequencies up to 200 MHz. Install it inline on the positive and negative leads near your sensitive gear, and watch the interference vanish. It's not just a band-aid; it's engineered for real-world durability in harsh environments.

Standout Features of the Newmar PC-25

• Heavy-Duty Build: Machined aluminum housing shrugs off vibration, corrosion, and extreme temperatures—perfect for marine decks or RV underbellies.
• Versatile Voltage Range: Handles 6-48 VDC systems, from small 12V setups to heavy-duty 24V or 48V industrial rigs.
• Easy Integration: Color-coded wire leads simplify inline installation—no special tools needed. Secure it with built-in mounting flanges for a rock-solid fit.
• High-Capacity Performance: Rated at 25 amps continuous, it powers demanding loads without breaking a sweat.
• Broad-Spectrum Filtering: Targets conducted noise effectively, keeping your audio crystal clear and visuals sharp.

Pro Tips for Installation and Maximum Results

1. Locate the Source: Position the PC-25 as close as possible to your radio, display, or other noise-sensitive device—typically within 1-2 feet of the power entry.
2. Wire It Right: Cut power leads, strip ends, and crimp color-coded wires securely. Use heat-shrink tubing for marine-grade waterproofing.
3. Mount Smart: Leverage the integral flanges to bolt it down away from heat sources like engines or exhausts.
4. Test Thoroughly: Fire up your alternator or motor post-install and scan frequencies—noise should drop dramatically.
5. Pair for Power: For alternator-heavy setups, combine with a Newmar 150A model upstream for total system cleanup.

Users report instant improvements: clearer ham radio contacts on the water or glitch-free entertainment in mobile homes.

Ideal Applications for the PC-25

This power conditioner thrives in:

• Marine environments: VHF radios, fishfinders, and autopilots free of alternator hash.
• RVs and trucks: Stabilizing inverters, LED lighting, and security cams.
• Off-grid solar: Cleaning battery bank output for sensitive inverters.
• Industrial vehicles: Protecting telemetry and sensors from motor noise.

Real-World Edge Over Basic Filters

Unlike generic suppressors that fizzle out under load, the PC-25's multi-stage design handles spikes and sustains filtering. Boaters praise its longevity in saltwater spray, while RV enthusiasts note zero failures after years of road abuse. If clean power reliability matters, this is your upgrade.
