PWM charge mode

Main characteristics:

1, the use of intelligent control

2, with over charge, over discharge, short circuit, overload protection, a unique electronic anti reverse connection protection automatic control; protecting more than does not damage any parts, do not burn the insurance.

3, using the battery discharge rate characteristic correction of discharge control. Final discharge voltage is determined by the rate of discharge curve correction of control point, eliminating the pure voltage control over discharge inaccuracies, consistent with the battery inherent characteristic, namely the different discharge rates with different end voltage, the storage battery has been the most effective use.

4, the series PWM main circuit of the charging, the charging circuit voltage loss than using diode charging circuit reduces nearly half, high charging efficiency3%-6%, increased power use time; put off recovery voltage, normal charge, floating charge automatic control mode to make system consists of longer service life; at the same time is accurate temperature compensation. The use of LED LED indicates the current battery status, allowing the user to know the use of. Digital memory settings, eliminating the error. Reliability more.

5, visual LED LED indicates the current battery status, to allow users to understand the use of;

6, all control using industrial grade chip (only on I industrial controller ), in the cold, high temperature, damp environment running freely. At the same time, the use of the crystal timing control, timing control accuracy.

7, cancel potentiometer adjustment control set points, and the use of the Flash memory recording each control point, make the set of digital potentiometer, eliminates the vibration displacement, temperature drift control point error reduced accuracy, reliability factor;

8, the use of digital LED display and setting, one-button operation can complete all the settings, the use is extremely convenient and intuitive,

9, volume is more compact, more convenient installation; and a better performance of the MOS tube, the driving load capacity.

10, utilizes a large area metal fins, cooling performance is good, allowing the controller to work more stable.
