All Charge Controllers
  • SMD assembly, greater reliability
  • New housing design
  • High current rated MOSFETs
  • High performance micro controller
  • More intuitive LED design
  • USB port for charging mobile phones or small music players
  • Easily accessible terminals
  • Easy mounting
  • The CMLup series of charge controllers are equipped with a number of outstanding features such as a status display, alarm, and safety functions.
  • The temperature-compensated, four-stage PWM charging algorithm (float-main-boost-equalization) is adjustable for sealed and vented lead-acid batteries.
  • The CMLup charge controller also allows either a SOC or voltage-controlled low-voltage disconnect.
  • Battery status is clearly indicated by three LEDs. An acoustic alarm warns about an impending low-voltage disconnect (LVD).
