1.   Basic Parameters

1.1 Input Voltage: DC4.75V-23V;

1.2 Output Adjustable from 0.93V to 20V (buck mode, input voltage must be at least 1.5V greater than output voltage)

Factory set output voltage is 14.4V

Module Control: Module has start button which can be opened and closed; Module has power LED to indicate output status
   1.3 Working Current: Maximum 3A continuous current output, Maximum 4A peak current output;

1.4 Working Mode: Control chip integrates MOSFET. Current mode control provides fast transient response and cycle-by-cycle current limit.

     An adjustable soft-start prevents inrush current at turn-on and in shutdown mode, the supply current drops below 1μA.

1.5 Work efficiency:>95% Up to 95% efficiency
1.6 Dimensions: 6.3cm (Length)*3.3cm (Width)*1.5cm (Height)

2.   Function description

2.1 Prevent battery return, back, counter current; adjustable output current; can be used as current regulating power panel.

2.2 Provide alternative solution to expensive solar controller. Features include over-load protection provided by pulse charge prolongs battery life; wide operating input range; 3A continuous output current; 4A peak output current; up to 95% efficiency. The product is used to charge a battery with different rated voltage (3.7V, 6V, 12V) through solar panels or other direct current.

 

2.3 Instructions:Output with the protection, but bear in mind that the input of plus or minus mustn't be reversed, connect line after make sure that the positive and negative terminal.
