Description
Phase Three "Smart" battery charging technology provides significant benefits over traditional float chargers whose output voltage droops under heavy loads, and fails to attain absorption voltage levels recommended by battery manufacturers as part of a proper charge cycle. Theses issues are particular significant in Emergency Vehicle applications where rapid recharge is required while powering DC loads, and reliable service life of a battery is critical. Smart Chargers interact with batteries and deliver a three stage charge process which provides for fastest recovery and ideal battery condition, maximizing performance and life.

Adaptability to different battery types and charge conditions is another important feature. A selector switch adjusts output voltage to adapt for proper charging of gel-cell, lead acid and AGM battery types. An optional temperature compensation sensor adjusts output for ideal voltage based on changes in ambient temperatures. This improves performance and extends battery life.

Power Returned to Battery by 14 Amp 3-Step Charger vs 15 Amp Float Charger
Conditions: 200 AH Battery, 75% Charged, 4 Amp Constant Load


The graph depicts the incremental power returned to batteries using a three step process which controls voltage depending on battery and load conditions, in comparison to float type chargers that regulates to a single end of charge voltage set point.

Temperature Compensation:
- 5 mV per cell per ˚C. Sensor supplied with 25' cable and plug-in connector
