12V/24V/36V/48V 30A Battery Overshoot & Over-Discharge Protection Automatic Shutdown Switch Module

12V24V36V48V 30A Battery Overshoot & Over-Discharge Protection Automatic Shutdown Switch Module 1. Charging mode IN: By setting the upper limit voltage UP and lower limit voltage dn; when the battery voltage is less than or equal to the lower limit voltage dn, the relay is turned on and the charger starts charging the battery; when the battery voltage is greater than or equal to the upper limit voltage UP, the relay is turned off and complete. One-time automatic charging; the relay is turned on and IN flashes, indicating that charging is in progress. 2. Discharge mode OUT: By setting the upper limit voltage UP and lower limit voltage dn; when the battery voltage ≥ the upper limit voltage UP, the relay is turned on and discharge starts; when the battery voltage is less than or equal to the lower limit voltage dn, the relay is turned off to complete an automatic discharge function; The relay is turned on and OUT flashes, indicating that it is discharging. 3. Chargedischarge time control function: When the set time parameter OP is non-zero, chargedischarge time control is started; when the relay is turned on to start a chargedischarge, the timing starts; when the timing is completed, the relay is automatically disconnected to complete a charge. Discharge process; if the timing is completed, in charging mode, the detection voltage is less than the lower limit voltage dn or in discharge mode, the detection voltage is greater than the upper limit voltage UP, the charging time control function will be automatically turned off, and H:ER will flash to remind the user that the time parameter setting is incorrect. Reasonable; press any key to stop flashing 4. When chargingdischarging time control is not turned on, the product will record a complete time. When entering the time display interface, the charging time will flash and display; it will be cleared when exiting the time display interface or the next charging is turned on (relay is turned on). 5. Automatic parameter detection: After setting the parameters and exiting, if the lower voltage limit
