Charge controller

Pulse Width Modulation (PWM)

KTF series


 12/24V auto work

KTF series is economic controller for solar home system, street light system and other small solar systems. All the electronic components are industrial grade without any mechanical switch. The electronic protections ensure the reliability of system.

  • High efficient series PWM charging
  • Use MOSFET as electronic switch
  • Intelligent system optimum control
  • Temperature compensation
  • LED indicators indicate battery voltage state
