A distinctive feature of this controller is that it can be connected to virtually any battery . This capability is achieved by setting the desired values of current and voltage in the menu controller. The current sensor in the controller is built on Hall Effect which improves the efficiency of the entire system. Another distinctive feature of this controller danogo Microprocessor control .
Principle of operation .
The controller dynamically check the current and voltage of the battery . When the battery is discharged , its resistance is small , so when charging through it can go high current ( greater than 1/ 10 of the container ) . Therefore, in the initial cycle battery controller ensures that the current does not exceed the value set in the menu. As charging battery resistance increases, the current decreases and begins to increase the voltage on the battery. Controller at this stage ensures that the voltage does not rise above the limit set in the menu. If the current or voltage within the established limits , the duty cycle of the PWM signal is increasing and energy thrown off by the ballast . All the excess energy that is produced by a wind turbine , the controller pulls on ballast (it can be any ten for heating water ) Note: Ballast must be chosen so that when a charged battery controller can download windmill , otherwise he will go into the dressing .
By default, the controller is configured to current 4 amps and voltage of 14.2 volts , if you need other size, they can be installed in the instrument menu . The LCD display shows the current and voltage battery charging , the power that goes to the battery and the duty cycle of the PWM signal (0 - maximum duty cycle of 255- minimum duty cycle ).
