Alpha Industrial Powers P45 Industrial Battery Charger incorporates the latest digital and power electronics technologies, making it one of the most reliable battery chargers available. The unique SCR rectifier with a double wound isolation transformer provides precise regulated DC output and current limiting capabilities. Three different output-filtering configurations are available to match powering requirements. The P45's graphical Interface, with its user definable controls and alarm set-points, allows the charger to be customized for the appropriate application. Approved for UL, CE, CSA and EMC standards.

  • Designed with the latest digital power electronics in the market
  • Microprocessor control
  • Provides regulated DC output and current limiting capabilities
  • Graphical interface allows for customization to individual applications
  • Wide temperature range 0 to 50°C
  • Approved for UL, CE, CSA, and EMC standards
