SMK Charger Controller
SMK Charger Controller
With the help of our foresight, we manufacture an efficient range of SMK Charger Controller. Our smk charger controller prevents overcharging and may prevent against over voltage, which can reduce battery performance or lifespan, and may pose a safety risk.

SMK Charger Controller Features:
  • Switched Mode operation
  • Charging topology Buck Mode CV charging – most suited for most Battery chemistries
  • Solar charging current up to 10 Amps continuous – customised designs are available for higher power ratings
  • Load current: Up to 10 Amps continuous – customised designs are available for higher power ratings. Available in 12V & 24V versions.
  • Low voltage Load disconnect: 11V Load Reconnect Voltage: 12.4V.
  • Night Time current drain: < 10 micro amps.
  • Automated frequency selection for wide input voltage range. Multiple steps of PWM provided for efficient charging.
  • LED indications provided for charge/float
  • LED indications also can be provided for battery level indicator on requirement
  • Red LED for Low-Voltage indication.
  • Uses pulsed float voltage maintenance mode when battery is full (13.5V).
  • Internal Temperature compensation provided, works well in cold and hot environments. RFI (Radio Frequency Interference) suppression, designed to work with radio systems.
  • Built in Automated Recovery thermal fuse for protection from excessive load and reverse battery protection – No technician required for maintenance.
