Sell ❏Battery Charge And Discharge Protector Module 12V48v Undervoltage And Overvoltage Relay Protection best price

Module Highlights: 1. Battery charge and discharge control automatically set off after setting; 2. Can set the charge and discharge time; 3. With serial communication function, the working status of the relay can be monitored in real-time through the serial port; 4. An additional signal output, when the relay conduction condition is met, the output level is high, and other devices can be controlled. 5. One button emergency stop function (STOP button), with reverse connection protection, the reverse connection does not burn; Operating mode: Upper voltage limit: UL1, lower voltage limit nL1, upper voltage limit is greater than the lower voltage limit (UL1>nL1) U-1: Charging measurement: When the measured voltage is lower than the lower limit voltage, the relay pulls in, the upper limit voltage is higher, and the relay is disconnected; U-2: Charging measurement time control: set charging time (OP); when the measured voltage is lower than the lower limit voltage, the relay is closed, and the OP time starts counting down after the pickup, the time is up, the relay is disconnected; above the upper limit voltage, the relay disconnect. U-3: Discharge detection: When the measured voltage is lower than the lower limit voltage, the relay is disconnected, higher than the upper limit voltage, and the relay is closed; U-4: Discharge detection time control: set discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay pulls in, the OP time starts counting down after the pull-in, the time is up, the relay is disconnected; when the measured voltage is lower than the lower limit voltage, the relay is disconnected; U-5: Interval in the interval: When the measured voltage is between the upper limit and the lower limit, the relay is closed and the other conditions are disconnected; U-6: Interval outside the range: When the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay is closed, and the relay is disconnected in other cases; Product parameters: 1: Supply voltage: DC6--40V, voltage detection range DC 0--60V, suitable for various batteries below 60V, voltage test error ± 0.1V. 2: Charge and discharge time (OP) range: 0--999 ​​minutes. 3: Weight 28G
