Solar voltage regulator charging module

Clear some stock solar regulated charging modules, support solar 14V-30V input, output voltage is 13.6V, can charge 12V battery and 12V lithium battery pack, using BM2596 voltage regulator

Name: Solar voltage regulator charging module

Both solar and other DC power sources are available

Input voltage: 14V ~ 30V

Input current: 3A

Output voltage: 13.6V ± 0.02V

Output current: 3A ( stable within 2A, over 2A for a long time, the temperature is too high, will power off protection)

Short circuit protection: yes

Overcurrent protection: self-recovery fuse (JK60 160)

 

DC-IN is the input positive pole, and PGND is the input negative pole.

DC-OUT is the positive output, and GND is the negative output.

 

The 12V battery has a limited voltage of 14.4V, and 13.6V is a safe voltage.

The 3 string 12V lithium battery pack needs to have a protection board, which can be charged with 12.6-14v.

 

The greater the power of the solar photovoltaic panel, the better. For example, the street lamp is 10 watts, and it is best to connect the photovoltaic panel above 20W.

 

The input is not connected to photovoltaic solar panels and other DC power supplies, and the battery terminal needs to be disconnected to avoid power loss.
