Battery Low Voltage Cut Off Automatic Switch On Protection

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.

Voltage Setting Method:
At setting mode(when display flashes), S1 button increases voltage value(add), S2 button reduces voltage value(minus).
S1 Under-voltage Setting(load stop):
At normal mode, press S1 button to show under-voltage value. Press and hold S1 button till display flashes, then adjust under-voltage value by pressing S1 and S2 button.
S2 Over-voltage Setting(load start):
At normal mode, press S2 button to show over-voltage value. Press and hold S2 button till display flashes, then adjust over-voltage value by pressing S1 and S2 button.
Restore to Factory Setting:
At normal state, press and hold S1 and S2 buttons together, till display shows 888, to restore to factory setting
Note: If S1 cannot be used to add voltage, set S2 first; if S2 cannot be used to minus voltage, set S1 first.
