Product Description
Features of SR-LG4860
1. The controller carried with LCM module which can display system
status and parameters
2. Parameters of charge and discharge are adjustable
3. Begin to ascending charging automatically when the voltage of
battery below the ascending charging recover voltage
4. 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.
5. The controller could figure out everyday’s power of charge and
discharge which make user assess the controller and entire system
more easily
6. With the charging current overload protection function, the
controller will reduce the charge current to protect the charging
circuit after it surpass the rated current.
7. A equalizing charge every 30 days in order to prevent battery
vulcanization
8. Industrial-grade chips and precision components makes the
controller can operate in any harsh environment
9. Design of double MOS series control circuit and PWM dim control
make the charging efficiency increased greatly
10. The setting parameter possess the saving function which makes
the parameter won’t be erased after losing the electricity and
system become more reliable.
11. Three kinds of load work mode: purely light-operated,
light-operated+time controlled,long-term on mode.
