Description

Feature:

1.Product name: 12V Automatic Battery Charging Power Supply Control Protection Board

2.When battery voltage is low at 10.5V, the module start charging automatic.

The module will turn off the power at 14.4V.

Red indicator will light on when charging, indicator light off when full-charged, the relay off and 220V input end.

Description:

1.The module using a dedicated voltage control IC and automotive-specific relay assembly,

2.Small size, large current, accurate turn-off voltage stability, protection and thoughtful, functional and reliable performance.

Function:

1.This module maximum limit 10A, please make sure less than 10A when use.

2.Battery automatic charging with the module detecting high and low level.

Adjust VR1:

Charger stop charging in the highest voltage. For example charger stop charging at 14.4V. Adjust clockwise is lower, anti-clockwise is larger.

Adjust VR2 :

Charger start to charging in the lowest voltage. For example charger start to charging so low as 10.5V. Adjust Clockwise is lower, anti-clockwise is larger

Produced before default:

Low voltage is about 10.5V, power turn off voltage is about 14.8V.

Installation wiring:

220V simply an arbitrary string into the relay COM line terminal.

(output) OFF terminal to charger. Charger must use the full bridge rectifier output.

The output voltage of DC is about 13.8V-14.8V.

Kindly reminder:

Do not touch the relay COM OFF ON three terminal with high-voltage, insulated and put into use please do.

Package include:

12V Automatic Battery Charging Power Supply Control Protection Board x 1 PCS
