Battery charging, small professional automatic adjustable module, high quality, easy to install for home and industry, precise and stable

Features:

1. Assembled with a special voltage control IC and a special automotive relay
2. Small size and high current
3. Precise and stable voltage cutoff
4. Full functions and reliable performance
5. Automatically charges and shuts off

Specifications:

Description: The 12V automatic charging power control protection board will automatically charge when the battery voltage drops to approximately 10.5V (adjustable low voltage) and will shut off when the power supply is approximately 14.4V (adjustable). Red light illuminates during charging and turns off when fully charged. Relay disconnection and 220V input load, thus saving energy.
Features:
1. Assembled with a special voltage control IC and a special automotive relay.
2. Small size and high current.
3. Precise and stable voltage switching.
4. Complete functions and reliable performance. 5. Automatic charging and shutdown.
Specifications:
PCB Size: 50 x 32 x 18 mm
Default Value:
Low Voltage: 10.5V
Shutdown Voltage: 14.8V (adjustable, may vary)
Wiring Method: Please wire according to the instructions. Do not modify the wiring.
Instructions:
Connect any 220V wire to the COM port of the relay and connect the charger to the OFF port.
The charger must be a fully bridge rectified output. The DC output voltage can be between 13.8 and 14.8 V. First-time load test: the battery voltage should be approximately 10 V. Function 1: the current cannot exceed 10 A. Function 2: the board has reverse connection protection. There is no output if no battery is connected. There is no output if the battery polarity is incorrect. Output short circuit automatically shuts off: this is a practical protection. As long as the output is short-circuited, the charger automatically shuts off the output, thus protecting the charger from damage. Setting: Relay VR1 is disconnected to stop when the battery charging voltage reaches 14.4 V. (Stop voltage setting: lower clockwise, upper counterclockwise)
Relay VR2 is connected and charging begins when the battery voltage reaches 10.5V (low voltage setting: lower clockwise, upper counterclockwise)
Package includes:
1 x Charge control board
