Description:

Name:Battery Charger Discharger Board & Undervoltage Overvoltage Protection Timing Charge and Discharge with Communication Function

Module highlights:

1. battery charging and discharging control, automatic power failure after setting.

2. can set charge and discharge time;

3. with serial communication function, the working state of the relay can be monitored in real time through the serial port.

4. extra signal output, which can control other devices when meeting the relay's conduction condition and output high level.

5., there is one button emergency stop function (STOP key), with reverse connection protection, reverse connection without burning.

Work model:

The upper voltage limit is UL1, the voltage limit is nL1, the voltage limit is greater than the voltage limit (UL1>nL1).

U-1: charging measurement: when the measuring voltage is lower than the lower limit voltage, the relay will pull in and exceed the upper limit voltage, and the relay will be disconnected.

U-2: charge measurement time control: set charge time (OP); when the measurement voltage is lower than the lower limit voltage, the relay suck in, after suction starts to OP time, the time is up, the relay is disconnected, the relay is higher than the upper limit voltage, the relay is disconnected.

U-3: discharge detection: when the measuring voltage is lower than the lower limit voltage, the relay is disconnected, higher than the upper limit voltage, and the relay is absorbed.

U-4: discharge detection time control: set discharge time (OP); when the measurement voltage is higher than the upper limit voltage, the relay suck in, after absorption, it starts to OP time. When the time comes, the relay is disconnected; when the measurement voltage is lower than the lower limit voltage, the relay is disconnected.

U-5: pull in the interval: when the measuring voltage is between the upper and lower limits, the relay will pull in and the rest will be disconnected.

Outside the U-6: interval suction: when the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay will pull in, and the relay will be disconnected in other cases.
