Powering your 24V marine electrical system demands reliability, especially when you're far from shore. The Newmar PT-24-60W steps in as a powerhouse 60A charger designed specifically for demanding marine environments. Drawing from 230V AC input, it delivers precise, three-stage "smart" charging to keep your gel-cell, flooded lead-acid, or AGM batteries in peak condition. Whether you're running a live-aboard yacht, workboat, or recreational cruiser, this charger ensures fast recovery after heavy use, optimal conditioning, and longer battery life—without the guesswork.
Backed by extensive safety and EMC compliances (EN, CE), this charger meets stringent marine standards, giving you peace of mind on the water.
Traditional chargers can undercharge or overheat batteries, leading to sulfation or early failure. The PT-24-60W's "smart" circuitry monitors voltage and current in real-time:
Add the optional TP temperature sensor, and it fine-tunes output based on ambient conditions—crucial in engine rooms where heat builds up. Skip equalization on this model, keeping things simple for sealed batteries.

Compact yet robust (A-6 case size), it fits snugly in tight bilge spaces or electrical panels.
Boat owners swear by this charger for its no-fuss reliability. On a 50-foot trawler, it revives twin 24V house banks after a weekend of anchor lights and fridge duty. Commercial operators appreciate the multi-bank isolation—charge start, house, and electronics batteries separately without cross-talk. Pair it with solar or generator inputs for hybrid setups, and you've got a system that stays online through rough seas or long passages.
Installation is straightforward: hardwire to shore power or a generator, connect to batteries with adequate cabling (consult ampacity charts for 60A runs), and select your battery type. Mount vertically for best convection cooling.
It works with gel-cell, flooded lead-acid, and AGM batteries via a built-in selector switch that sets optimal charge (28.0-28.4VDC) and float (26.8-27.2VDC) voltages.
Yes, it functions as a stable 24V power supply for direct DC loads, with current limiting for safety.
An optional TP sensor automatically adjusts output voltage based on battery temperature, ideal for varying marine climates.
Three fully isolated banks, perfect for separating house, engine start, and auxiliary batteries.
Full 60A output from -20°C to +50°C (T-6 rating), with derating beyond for reliability in engine spaces.
No remote panel for this model, but onboard LEDs clearly show charge status and alarms.
Absolutely—optimized for 120-600 Ah systems, common on mid-to-large vessels with inverters or heavy electronics.
Phase Three "Smart" battery charging technology is now available in a wide range of power levels, allowing you to select the right size, features and flexibility you require for virtually any application from small recreational craft to large live-aboards, workboats and other commercial vessels. These chargers interact with batteries to put them through the optimum three stage charge process which provides for fastest recovery and ideal conditioning, maximizing battery performance and extending battery life.
A selector switch adjusts output voltage to adapt for gel-cell/flooded lead-acid/AGM battery types. An optional temperature compensation sensor also adjusts output for ideal voltage based on changes in the batteries' ambient temperature. All models are 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.
