PT-40U Battery Charger

Newmar’s Phase Three Series Battery Chargers employ “Smart” battery charging technology for 12-volt systems aboard marine applications including workboats, military vessels, commercial vessels, and recreational craft. This charger interacts with batteries, providing the optimum three-stage charge process for fast recovery and conditioning, maximizing performance, and extending battery life.

A selector switch adjusts output voltage to adapt to gel-cell, flooded lead-acid, or AGM battery types. An optional temperature compensation sensor also adjusts output for ideal voltage based on changes in the batteries’ ambient temperature. This model is housed in a rugged stainless steel case with a durable white powder coat finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.

Features:

  • 12-volt model
  • “Smart” circuitry provides three-stage charging – bulk, absorption, and float
  • Gel-Cell/Flooded Lead-acid/AGM battery type switch selects optimum charge/float voltages
  • Multiple isolated output banks; ammeter indicates total output current. (Except PT-7)
  • The optional sensor adjusts the output voltage based on battery temperature. (Except PT-7)
  • Current limitations prevent damage from overloading
  • Clean well-regulated output can be used as a power supply; can power loads directly without a battery in line
  • Built to last – rugged stainless steel case with a durable white powder coat finish, an optional drip shield, and marinized internal circuitry
  • Protection: Current Limiting, Thermal Protection, Forced Air Cooling, Drip Shield
  • ABS-type approval for battery charging and power supplies

Won’t cut
Color: Green
I have bought two of these The first wouldn’t cut so it was returned and replaced with another one that also would not cut. Wouldn’t recommend buying these at all.
