PT-24-60W - Newmar Power Newmar PT-24-60W Battery Charger

PT-24-60W Battery Charger

Marine battery charging technology for 24V systems aboard workboats, military vessels, commercial vessels, and recreational craft. This charger interacts with batteries, providing a three-stage charge process for 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 voltage based on changes in the batteries’ ambient temperature. All models are housed in a stainless steel case with a white powder coat finish, and the internal circuitry is polyurethane coated for corrosion resistance.

Features:

• 24V model
• Circuitry provides three-stage charging – bulk, absorption, float
• Gel-cell/Flooded Lead-acid/AGM battery type switch selects charge/float voltages
• Multiple isolated output banks; ammeter indicates total output current
• The optional sensor adjusts output voltage based on battery temperature
• Current limiting prevents damage from overloading
• Use as a power supply; can power loads without a battery in line
• Built to last – stainless steel case with a white powder coat finish with an optional drip shield and marinized internal circuitry

The Newmar PT-24-60W Battery Charger is designed for 24V marine electrical systems, suitable for workboats, military vessels, commercial vessels, and recreational craft. This unit provides a three-stage charging process (bulk, absorption, float) to condition and maintain battery performance, aiming to extend battery lifespan. It features a selector switch to adjust output voltage for gel-cell, flooded lead-acid, or AGM battery types. An optional temperature compensation sensor is available to adapt output based on ambient battery temperature. The charger is housed in a stainless steel case with a white powder coat finish, and its internal circuitry is polyurethane coated for corrosion resistance. It can also function as a power supply, capable of powering loads without a battery connected. Key protections include current limiting, thermal protection, and forced air cooling. This charger is intended for IT and marine professionals requiring a robust and adaptable charging solution for critical 24V battery banks.
