Product: 12V automatic charging power supply control and protection board, when the battery voltage drops to about 12.4V (low pressure adjustable), the protection board automatically in charge, turn off the power to about 14.8V When (as voltage is adjustable). When charging red light, full of red light off, the relay off the end of the charging 220V inputs, and thus play the energy saving effect.

 

Function: This plate transformer maximum limit 2000W, to detect high and low battery by protecting the management board to carry out automatic charging. (--- ayanhu81 ebay shop welcome you to buy it ---)

 

Adjustment: VR1 make battery voltage charge to 14.8V relay off, charging is completed. (As voltage setting: Clockwise low, counterclockwise high)

 

Adjustment: VR2 so low as 12.4V battery voltage relay start charging. (Low Voltage Setting: Low clockwise, counterclockwise high)

 

Description: This plate using a dedicated voltage control IC and automotive-specific relay assembly, small size, current, accurate turn-off voltage stability, protection and thoughtful, functional, reliable performance, really it makes you worry .PCB Size: 45 * 38 * 20MM (--- ayanhu81 ebay shop welcome you to buy it ---)

 

Produced before default: low pressure of about 12.4V. As voltage is about 14.8V.

 

Installation Wiring: 220V simply an arbitrary string into the relay COM line terminal (output) OFF-to-charger, as shown below: (Default delivery item not contain voltmeter, Buyers need to buy their own)

 

Friendly reminder: Do not touch the relay COM OFF ON three terminals with high-voltage, insulated and put into use please do.  (--- ayanhu81 ebay shop welcome you to buy it ---)
