Description:
Products features
1, The series of the small system is a set of supply power system, design for the people who living at distance countryside and the place lack of power, also can use at outdoor when working and travel, as the supplier for the small DC direct power
2, Reach the effect of intellect control through CPU and special used control arithmetic
3, Two kind of style working: 4 direct power output by the volt of 12, 2 PCS direct power output which is can be adjusted by the volt of 12
4, Can amendment the discharge power rate, different discharge rate have different final voltage, fit with the battery's feature
5, The science way of management for the battery, when over discharged, it will advance the voltage charge to the battery, can reach the effect of compensation of maintenance, when in normal use, using the charging way combine direct charge with float charge, advance charge every 7 days, protect the battery from vulcanization, prolong the service live, meantime have the high-accuracy compensation of the temperature.
6, Charging circuit adopt double MOS series connection control circuit, make the damage of the voltage of circuit less haft than the two-electrode valve circuit, charging adopt PWM fuzzy control, improve the charge efficiency, increased electric time greatly.
7, LED direct displays the status of solar cells, batteries, and load. Let the user know in real time of system.
8, With protection of overcharge, over discharge, overload, and special protection of electrical short circuit and anti- reverse connection, all protection without damage to any parts, won't burn insurance; Lightning protection with TVS, no Jmp line design, can improve system's reliability and durability.
9, All control use of industrial grade chips and precision components, it can work at cold, heat, damp situations
System specification
The system take Parameter samples by computer chip to battery voltage, and light battery voltage, and discharge current, and environment temperature, calculated by special control model, achive the piont which fit with the battery characteristics discharge rate, and high accurate control of temperature compensation amendment, and using intelligent efficient way of PWM fuzzy charged to charge battery. Using 4 paragraph type control voltage, assure battery work in best state, greatly extended battery service life.
