A.This product is composed of dc power system,especially design for users in remote parts of power shortage country,field work and camping trip,also use for small dc electric power supply.
B.System main circuit adopts the high performance and high precision of 10 AD single chip processor as the main controller,has a variety of functions,such as battery charged too much and excessive discharge protection,when excessive discharge voltage within the prescribed scope,working state will changed from green to red and green lights shine and close all the output.
C.This product has multiple dc output interface,can meet various needs,output interface contains 4*12V dc output and 1*5V USB output.
2.Function Features
A. With single chip processor as the main controller,when the system is over charge and over discharge to intelligent management.Overcharge and over discharge protection function can prolong battery efficiency.
B. Low power consumption standby function:5 minutes later,if there is no detected output load,system will automatically switch to low power standby mode.
C. USB output overload protection:when charging as for mobile phone,MP3 and digital camera,etc.if the maximum output current 1000mA,USB output will shut down automatically.
D. Overload protection:when the lighting more than 3A,system is in the automatic protection,output automatically shut down.
E. Independance charge,discharge:when the product is in charge,it also be used for other products between each other.
F.Powerful monitoring and prompt:this system in addition to over charge,over fall,over-current protectionfunction,it also have the input,output short circuit functions,when you encounter these situations,system will be in the form of a bright red light to remind you until you remove the corresponding fault.
G. This system can use ac adapter to charge.
