SR LG4860 PROPERTIES

 

Features 

  • Common cathode design adopted.

  • LCD screen for displaying system working status and parameters.

  • Adjustable charge and discharge controlling parameter.

  • Boost Charge mode auto shifts on when the battery voltage is lower than boost charge return voltage.

  • Double temperature sensors design, inner sensor for inside temperature detection, and the outer independent sensor for detecting battery temperature which makes the battery temperature compensation more precise.

  • The controller can work out daily battery charging and discharging capacity which makes it more convenient to evaluate controllers and the whole system.

  • It possesses overcurrent protection when charging which can decrease the charging current so as to protect the charge circuit if it exceeds the rated current.

  • It will proceed equalizing charge every 30 days to protect the battery from vulcanizing.

  • Industrial grade chips and precision components adopted which can work under cold, hot and moist conditions.

  • Double MOS in series circuit adopted in charge circuit, PWM charging control to improve charge efficiency.

  • Power-fail protection for saving tech data which makes the system operation more reliable.

  • 3 different load working modes: Pure light control, Lighting + Timing control, load open all time.
