All Charge Controllers
  • Battery State-of-Charge display with 3 LEDs
  • Acoustic load disconnect pre-warning
  • PWM-regulation (series type)
  • Boost, equalize and float charging, also for VRLA
  • Automatic 12/24 V detection
  • Integrated temperature compensation
  • Large terminals (up to 16 mm2 wire size)
  • SOC and voltage controlled LVD
  • Fully electronically protected
  • The CML series is a sophisticated solar charge controller family for low cost applications. The electronic circuit is equipped with a microcontroller that provides high- efficiency charging technology together with a number of outstanding status display, warning and safety functions. The temperature-compensated three-stage PWM charging method (boost-equalization-float) is now adjustable tosealed and vented lead-acid batteries. The new version also allows an either SOC or voltage controlled low voltage disconnect function. The battery status is clearly indicated by three LEDs.
  • As the first controller on the market in this price range it comes with an acoustic low voltage load disconnect pre- warning feature.
