12V Storage Battery Protection Board Undervoltage Automatically Turn OnOff Controller Module

Features: This is a undervoltage switch module used to turn off the power of resistive load in the event of the voltage dropping below a definite value(set undervoltage). If the voltage rises back in 6 seconds, the module will keep load turning on. When the battery voltage increases to a certain value(set overvoltage), the module will automatically turn on load again. Designed with a LED indicator to show if load is cut off or turned on. Both undervoltage cutoff value and overvoltage turnon value can be adjusted by simply pressing buttons. Specifications: Input Voltage: DC12V Max. Current: 10A Size: 50*48*20mm1.96*1.89*0.78" Instruction: Load cut off and turn on: For 12V storage battery, set undervoltage (load cut off voltage) as 10.5V, when the battery voltage drops to 10.5V or lower, controller will delay 6 seconds then cut off load. If voltage increases in the delayed 6 seconds, load will keep turning on. Voltage setting: Under the value setting condition as display flashes, press start button to increase voltage, and stop button to reduce voltage. Start button function(setting undervoltage for cutting off load): Under normal voltage display condition, press start button to display undervoltage value. Press and hold start button till display flashes, then press start or stop button to set undervoltage value. Stop button function(setting overvoltage for turning on load): Under normal voltage display condition, press stop button to display overvoltage value. Press and hold stop button till display flashes, then press start or stop button to set overvoltage value. Restore to factory settings: Press and hold start and stop button together till it displays 888 to restore factory settings. Note: When setting, if start voltage cannot be adjusted, you can adjust stop voltage first. This is not a circuit problem or program fault.
