12V Battery Low Voltage Cut off Automatic Switch On Protection Undervoltage

Features: This is a under-voltage switch controller used to turn off the power of load in the event of the voltage dropping below a set value. When the battery voltage increases to a set value, the module will automatically turn on load again. Designed with a LED indicator to show if battery is under-voltage. Both turn-off and turn-on voltage value can be adjusted by simply pressing buttons. This controller will help you to protect battery from over-discharging and prolong battery life. Specifications: Suitable Battery: 12V storage/lithium battery Control Current: 20A Control Precision: 0.1V Voltage Error: 0.1V Size: 8x4.3x2.8cm/3.1x1.7x1.1in Weight: 41g(approx.) Restore to Factory Setting: At normal state, press and hold S1 and S2 buttons together, till display shows 888, to restore to factory setting. Function:  When our set voltage is 10.5V under-voltage shutdown, when the voltage is below 10.5V, if the voltage returns to above 10.5V within 5 seconds, the load will not be turned off. If it is still lower than 10.5V within 5 seconds, then turn off the load. This function is to prevent the misoperation of pulling down the voltage when a large current load is started. Package Includes: 1 x Battery Under-voltage Controller
