SR LG4845 PROPERTIES

 

Features 

  • The controller carried with LCM module which can display system status and parameters

  • Begin to ascending charging automatically when the voltage of battery below the ascending charging recover voltage

  • Temperature compensation become more accurate due to Double temperature sensors design,inner temperature sensor test the inner temperature of the controller,outer temperature sensor test the outer temperature of the controller.

  • The controller could figure out everyday’s power of charge and discharge which make user assess the controller and entire system more easily

  • With charging current overload protection function, controller will reduce charge current to protect the charging circuit after it surpass the rated current.

  • A equalizing charge every 30 days in order to prevent battery vulcanization

  • Industrial-grade chips and precision components makes the controller can operate in any harsh environment

  • Design of double MOS series control circuit and PWM dim control make the charging efficiency increased greatly

  • The parameter possess saving function which makes the parameter never be erased after losing the electricity and system become more reliable.

  • Three kinds of load work mode: purely light-operated, light-operated+time controlled,long-term on mode.
