4.Using Steps:
-
Connect right input voltage at input terminal.
-
Check output voltage by voltmeter and ammeter.
-
Connect battery to B+ and B-.
Note:
-
Its max output current is 1A and can't keep output 1A.
-
The positive and negative poles of the input power supply cannot be reversed. Otherwise, the module will be damaged.
-
Users can install a common anode Red-Blue LED by yourself as charging indicators. blue light indicates whether there is a load on output. hold Red is charging. there is no battery when flashing Red. Red OFF when charged.
-
Due to the large current, it is recommended to use a thicker wire. wire cross-section greater than 1.5 square millimeters.
-
Please read use manual and description before use.
- JP1 is to output voltage (short circuit is 12V output, disconnected is 9V output).
-
JP2 is to charge current for the battery (short circuit is about 1A, disconnection is about 0.5A).
