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.
