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. Charge/discharge time control function: When the set time parameter OP is non-zero, charge/discharge time control is started; when the relay is turned on to start a charge/discharge, 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 flashing4. When charging/discharging 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 dn ≥ the upper limit voltage up, the system will flash "ERR" as a reminder.6. Discharge conduction forced start time FOP (0~10S): After the relay conduction conditions are met, the relay is forced to conduct (0~10S) and the battery voltage is detected again; this function is mainly for the discharge function, and some test loads are At the moment of conduction, it will be instantly pulled down to the lower limit voltage, causing the relay to be disconnected due to false triggering, and the normal discharge process cannot be carried out.7. Dimensions: 62x57x22mm8. Weight: 51 grams9. Note: This product is a simple voltage controller that turns on and off the output through a relay. It only functions as a switch and cannot transform voltage.
