PT-25W 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
