Phase Three Series Battery Chargers

Newmar’s Phase Three “Smart” Battery Chargers wide model range covers battery systems ratings from 14-1000 amp-hours for 12, 24 and 32V DC battery systems.

Three Stage “Smart” Chargers

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 providing quick recharge of auxiliary batteries in vehicles parked in the station house, to powering continuous loads and maintaining peak charge in large battery systems in remote communication sites as well as industrial generator and marine applications. 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 with a durable white powder coat finish, and the internal circuitry is polyurethane coated for maximum corrosion resistance.
