12V 24V 36V 48V maximum current 30A battery anti-discharge protection board, simple and practical, with alarm tips, while versatility, it can be said for all the load. This module with a delay alarm, that is, after the battery undervoltage delay 5 to 20 seconds, if the battery is still undervoltage, the module will alarm at the same time disconnect the output, so you can avoid the high current load when the battery voltage fluctuations Wrong move.
Wiring method as shown in the main picture (input without anti-protection, before wiring, please distinguish between positive and negative):
Example 1: If the load is a motor, start, the battery voltage will fluctuate, this can be used with a delay, delay 5 to 20 seconds enough to restore the battery voltage stability.
Example 2: the car just started, the car will flash the lights, but also because the start when the current is relatively large, the battery voltage fluctuations, and this delay can be used, the delay of 5 to 20 seconds, enough to make the battery The voltage is restored.
This module alarm for the self-locking type: 5-20 seconds after the battery undervoltage, the module automatically disconnect the output, when the battery voltage itself rises above the set value, is not re-connected to the load, you need to manually disconnect the module Of the input can be restarted, the buyer can own the battery cathode and the module positive input string a normally closed switch can be easily controlled.
For example, the 12V battery, for example, when the battery voltage is normal, the board on the work light is on, the output is connected; when the battery appears over discharge (less than 10.V-11.5V), the board will automatically disconnect the battery Output, undervoltage indicator light and the buzzer alarm, in order to achieve the battery discharge state, to prevent the battery is too discharge, damage the battery.
12V battery, adjusted to about 10.5V protection (default delivery)
24V battery, adjusted to about 21V protection
36V battery, adjusted to about 31V protection
48V battery, adjusted to about 42V protection
The buyer can adjust the value of the undervoltage protection, clockwise to increase the voltage value of the undervoltage, counterclockwise to adjust the voltage to reduce the undervoltage.
1, with sound and light alarm, there is no protective effect directly;
3, the maximum allowable board through the 30A current, suitable for most of the battery;
30A refers to the relay contact by the load current (that is, your load can not exceed 30A current), not the battery current (capacity)
Static: consumes about 12mA (when the battery voltage is normal);
Dynamic: consumes about 100mA (battery undervoltage);
