Solar controller charging and discharging

 

Main features:

1, use discharge rate characteristics of fixed battery accurate discharge control. Discharge from the discharge end voltage is rate curve mend the control points, eliminate the pure voltage control discharge inacurate, accord with battery of inherent characteristics, that is, different discharge rate with different end voltage.

2, has used the single-chip microcomputer and special software, realize the intelligent control;

3, overcharge, discharge, electronic short circuit, overload protection, unique meter protector against fraud protection automatic control; All above protection without causing damage to any component, doesn't burn insurance;

4, adopted PWM charging series main circuit, make charging loop voltage loss of use of the diode is charging circuit reduce nearly half, charging efficiency is not high PWM 3% 6%, increased the power of time; Discharge the ascension of the recovery charge, normal fill continuously, float the automatic control system filling way by a longer service life; At the same time a high precision temperature compensation;

5, intuitive LED tube current battery state instructions, let users understand the use situation;

6, all control all adopt the industrial chip (only to take I industrial controller), can in cold, high temperature, moisture environment running freely. Use both crystals timing, timing control precision.

7, cancelled potentiometer adjustment control set point, and use the Flash memory recording the work of the control points, to set up the digital, eliminate the potential for a WenPiao, such as partial vibration control points appear to reduce error accuracy, reliability factors;

8, use the digital LED display and setting, a key type operation can complete all Settings, use very convenient, intuitive, and

9, with dc output or 1 HZ stroboscopic output 2 kinds of output choice, stroboscopic output is especially suitable for the LED traffic warning, etc.
