Newmar PT-14W Battery Charger

The PT-14W Battery Charger by Newmar is engineered for marine applications, providing reliable and efficient charging for 12-volt systems on workboats, military vessels, commercial ships, and recreational boats. Utilizing advanced “Smart” charging technology, this charger ensures optimal battery performance, fast recovery, and extended battery life through a precise three-stage charging process.

Advanced Charging Technology

Newmar’s Phase Three Series Battery Chargers interact intelligently with your batteries, delivering a comprehensive charging cycle that includes bulk, absorption, and float stages. This method not only accelerates battery recovery but also conditions the cells to maximize their performance and longevity.

Versatile Battery Compatibility

The PT-14W features a selector switch that allows you to adjust the output voltage to suit various battery types, including gel-cell, flooded lead-acid, and AGM batteries. Additionally, an optional temperature compensation sensor can be integrated to modify the output voltage based on ambient temperature changes, ensuring your batteries receive the ideal charge under varying conditions.

Durable Construction for Marine Environments

Designed for the harsh marine environment, the PT-14W is housed in a rugged stainless-steel case with a durable white powder coat finish. The internal circuitry is protected with a polyurethane coating, offering maximum resistance to corrosion and ensuring long-lasting performance even in challenging conditions.

Key Features

• Three-stage charging: bulk, absorption, float for efficient battery maintenance
• Adjustable charge/float voltages for Gel-Cell, Flooded Lead-acid, and AGM batteries
• Multiple isolated output banks with ammeter for total output current monitoring (Excludes PT-7)
• Optional temperature compensation sensor for optimal voltage adjustment based on battery temperature (Excludes PT-7)
• Built-in current limiting to prevent damage from overloading
• Clean, regulated output suitable for use as a power supply; can power loads directly without a battery
• Robust stainless-steel construction with white powder coat finish and optional drip shield
• Comprehensive protection features: Current Limiting, Thermal Protection, Forced Air Cooling, Drip Shield
• ABS-approved for battery charging and power supply applications
