12V Universal Battery Over-discharge Protection Board Low Battery Protection Board

Description:
 
12V maximum current 30A battery protection against over-discharge protection board, simple and practical, with alarm, and versatility, it can be said for all loads. This module has a delay alarm, which is delayed by 5 to 20 seconds after the battery is under voltage. If the battery is still under voltage, the module will alarm and disconnect the output. This avoids errors due to battery voltage fluctuations at high current loads. action. Wiring method as shown above (input without reverse protection, please distinguish positive and negative before wiring)
 
Example 1: If the load is a motor, the voltage of the battery will fluctuate at startup. This delay can be used. A delay of 5 to 20 seconds is enough to restore the battery voltage to a stable value.
Example 2: When the car is just starting up, the lights in the car will flash, but also because the current at startup is relatively large, the battery voltage fluctuates, and this delay can be used, the delay is 5 to 20 seconds, enough for the battery The voltage is restored.
This module is self-locking alarm type: 5 to 20 seconds after the battery is under voltage, the module will automatically disconnect the output. When the battery voltage rises above the set value, the load will not be switched on again. It is necessary to manually disconnect the module. After the input can be restarted, you can easily control the battery positive and the positive input of the module by a normally closed switch.
 
Features:
 
1. With sound and light alarm, there is no protection directly and clearly;
2. Strong versatility;
3. The board allows a maximum of 30A current, suitable for most of the battery;
30A refers to the load current of the relay contact (ie, your load cannot exceed 30A), not the battery current (capacity)
Static: Consumed about 12 mA (when battery voltage is normal);
Dynamic: Consumed about 100 mA (when the battery is under voltage).
