Module Features:
1. Power supply anti-reverse protection.
2. 1% high-precision voltage divider resistors make the measured voltage more accurate. The voltage dividing resistors of other manufacturers are 5% accurate.
3 .The voltage accuracy and resolution are 0.1V, and it has a calibration function.
4. Reduce the brightness of the digital tube display, save energy and protect the eyes.
4 The parameters are saved after power off, avoiding repeated settings.
5 .There are digital tube sleep mode and restore factory function.
6. It has a one-button emergency stop (STOP button) function, short press allows the relay to be turned on or does not allow the relay to be turned on.
7. Add an additional control signal output (drive current 100MA), when the relay is on, the output is high level, and when the relay is off, the output is low level.
8. In U-2/U-4 mode, you can set the charging and discharging time (OP), range: 0~999 minutes.
9 .After the parameters are set, the charging and discharging of the battery is automatically controlled.

Notice:
1 This is a 0-60V battery charge and discharge protection board, it cannot replace the battery charger.
2 The valid condition of charging time (OP) is: in U-2/U-4 mode, when the voltage is between the upper and lower limit voltage

Working mode:
Upper Limit Voltage: UL1, Lower Limit Voltage nL1, the Upper Limit Voltage must be greater than the Lower Limit Voltage (UL1>nL1).

U-1: Charging: When the measured voltage is lower than the lower limit voltage, the relay is turned on, and when it is higher than the upper limit voltage, the relay is turned off;

U-2: Charging time control: Set the charging time (OP); when the measured voltage is lower than the lower limit voltage, the relay will be turned on, and the OP time will be counted down after it is turned on. When the time is up, the relay will be turned off. If the measured voltage is still lower than the lower limit If the voltage is higher than the upper limit voltage, the relay will be disconnected.

U-3: Discharge: When the measured voltage is lower than the lower limit voltage, the relay is disconnected, and when it is higher than the upper limit voltage, the relay is turned on;

U-4: Discharge time control: set the discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay will be turned on, and the OP time will be counted down after it is turned on. When the time is up, the relay will be turned off. If the measured voltage is still higher than the upper limit voltage, the timer will be restarted; when the measured voltage is lower than the lower limit voltage, the relay will be disconnected;

U-5: conduction between the upper limit voltage and the lower limit voltage: when the measured voltage is between the upper limit and the lower limit, the relay is turned on, and otherwise it is turned off;

U-6: Conduction outside the interval between the upper limit voltage and the lower limit voltage: when the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay is turned on, and in other cases the relay is turned off;
