Product Overview

Phase Three PT-40U Marine Battery Charger

The Newmar PT-40U is engineered for 12-volt applications in the marine environment, catering to workboats, military craft, commercial vessels, and recreational boats. It utilizes advanced 'Smart' battery charging technology, facilitating a three-stage charge cycle that ensures efficient battery recovery, conditioning, and longevity.

A user-friendly selector switch enables adaptation to various battery types including gel-cell, flooded lead-acid, and AGM. For optimal charging, an optional temperature compensation sensor modifies the output voltage based on ambient temperature changes. Housed in a durable stainless steel casing with a weather-resistant powder coat finish, this charger is designed for harsh marine conditions with internal circuitry coated for corrosion resistance.

Features:

  • 12-volt charging model optimized for marine applications
  • Three-stage charging process: bulk, absorption, and float
  • Selector switch for different battery types: Gel-Cell, Flooded Lead-acid, AGM
  • Multiple isolated output banks with an ammeter for total output current
  • Optional temperature sensor to adjust voltage output
  • Current limitations to prevent overload damage
  • Stable output can serve as a power supply, enabling direct load usage without a battery
  • Durable construction with a stainless steel casing and protective powder coat
  • Includes features like Current Limiting, Thermal Protection, and Forced Air Cooling
  • Meets compliance for battery charging and power supply standards
