The NewMar PT-24-45U is a professional-grade 24-volt battery charger designed for marine applications including workboats, military vessels, commercial vessels, and recreational craft. This intelligent charger delivers 45 amps of output across three isolated charging banks, utilizing advanced three-stage charging technology to optimize battery performance and longevity.
Smart Three-Stage Charging Technology:
The PT-24-45U automatically progresses through bulk, absorption, and float charging stages to provide the ideal charge profile for your batteries. A convenient selector switch adjusts output voltage to match gel-cell, flooded lead-acid, or AGM battery types, ensuring compatibility with virtually any 24-volt battery system. The charger is recommended for battery banks ranging from 90 to 450 amp-hours.
Key Features:
- Three isolated output banks with 45-amp total capacity; ammeter displays total output current
- Universal input voltage: 90-264 VAC, 50-60 Hz with high power factor (.98 @ 115V, .95 @ 230V)
- Battery type selector optimizes charge/float voltages for gel-cell, flooded lead-acid, or AGM batteries
- Optional temperature compensation sensor (TCS-12/24) automatically adjusts voltage based on ambient temperature
- Can function as a power supply to operate loads without batteries connected
- Current limiting protection prevents damage from overloading
- Compatible with optional remote panel (RP model) for charge cycle monitoring and manual re-initialization
- Works with PT-MCU for enhanced control and monitoring capabilities
- ABS type-approved for battery charging and power supply applications
Rugged Marine Construction:
Built to withstand harsh marine environments, the PT-24-45U features a robust stainless steel enclosure with durable white powder coat finish. Internal circuitry is polyurethane coated for maximum corrosion resistance. Protection features include current limiting, thermal protection, forced air cooling, and optional drip shield. Operating temperature range: -20°C to +70°C (output derates linearly from 100% at 50°C to 50% at 70°C).
