Features:
1. Using single-chip microcomputer and special software; special software based on expert control system is adopted, which realizes intelligent optimization SOC control.
2. Temperature compensation adopts the external temperature sensor, which is more accurate than built-in humidity sensor.
3. With overcharge, over-discharge, electronic short circuit, overload protection and unique anti-reserve protection; none of the above protections will damage any parts, and do not burn insurance.
4. Tandem PWM charging main circuit makes voltage loss of the charging circuit decrease nearly half of that of diode charging circuit. And the charging efficiency is 3%-6% higher than non PWM, increasing using time, enabling a longer system service life. It also has high precision temperature compensation.
5. The obvious LED light tube indicates the current state of the battery, so that user can understand the working condition.
6. Industrial-grade control chip to ensure normal operation in cold, high temperature and humid environment; the crystal vibration timing control is used to ensure timing precision.
7.LED digital tube display setting, an one-button operation can complete all settings;
8. Using advanced power technology, the effective power of unit area is greatly improved and the structure is more compact.
9. Built-in super strong voltage correction program ensures the accuracy of voltage at all levels and controls the correctness of charging and discharging process.
10. Half power regulating function makes the lamps and lanterns can be transferred to work to half power energy saving state, greatly reducing the load of energy consumption and extending the time of normal system work.
11. With constant current output function, it can directly drive LED load, and constant output current can be adjusted with load power. Changing conventional LED light source needs adding constant current source; more convenient installation, reserving more space.
12. With large diameter and large spacing terminals, it can be installed with the maximum 6mm conductor with a 9.5mm interval distance, which enhances insulation performance and installation reliability, and is not easy to slide.
