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.
Features
• “Smart” circuitry provides three stage charging—bulk, absorption, float
• Gel-Cell/Flooded Lead-acid/AGM battery type switch selects optimum
charge/float voltages
• Multiple isolated outputs - charge independent battery banks*
• Optional sensor adjusts output voltage based on battery temperature*
• Current limiting - charges dead batteries without overload
• Use as a power supply; can power Radios/MDT’s without a battery in line
• Built to last—rugged stainless steel case with circuitry hardened for hostile environments
