JC48V40A LCD series controller

Specifications

1). Product picture,dimension figure

2).Technical parameters:

The solar controller is the most important part of the solar system. It is too intelligent and automatically to control the charge, discharge and load of the system. The performance of the controller can influence the stability of the system, especially the lifetime of Battery.

JC series solar controller will supply perfect protection functions for the battery; it will make battery work reliability. And the controller could be widely used in the solar system such as lamps, pastoral, frontier and island and so on, it is also could be used for mobile basics, microwave stations and traffic systems.

Theory introduction:

Use the industrial MCU as the host controller. According to the surrounding temperature, the voltage and ampere of battery

and solar cell, on or off the MOSFET, to achieve the function of control and protection.

Function: Battery Overcharge and charge protection; Battery Open-circuited protection; Load Over-voltage protection; Reversed charge protection at night; Flow and short circuit protection; Battery Open-circuited protection; Solar Cells Reversed protection; Over-voltage protection; Temperature Compensation (automatic identification of the temperature sensor is online)

Protection function:

1.Battery Reversed protection: The "+" and "-" polarity reversed, please replace the fuse.

2.Solar Cells Reversed protection: the "+" and "-" polarity reversed, Please replace the polarity.

3.Flow and short circuit protection: the loads exceed rated current or load short circuit, please replace the fuse.                                        

4.Battery Open-circuited protection: When battery open-circuited, but the solar cell charging normally, the controller will cut-off the load.

5.Overcharge protection: When the charging voltage higher than protection voltage (14.4V/28.8V/57.6V), the controller will shut off the charging automatically, When the voltage drop to the maintain voltage (13.8V/27.6V/55.2V), the battery go into the floating station. When the charging voltage lowers than recovery voltage (13.3V/26.6V/53.2V), the floating shut off, and come into equalized charging.

6.When the battery voltage under protection voltage, the controller will shut off the output automatically to protect the battery.

7.Over-voltage protection: When the voltage is higher, the output will shut-off automatically to protect appliances. LCD display power over, in the mean time the LCD backlight flashing.

Installation and usage:

please connect as the following picture. Please pay attention to the “+” and “-” polarity. Firstly, connect the battery; then the solar cells, at last the appliances. The LCD displays the current battery charge status and charge level. THE red LED indicates a battery is charging. And the green LED is discharge instruction. To prevent the wrong action, under voltage protection, under voltage recovery and over pressure recovery have 10 seconds delay. Over voltage protection has no delay time.
