2PCS DC 640V Battery Charger Discharger Control Switch Undervoltage Overvoltage Protection Board Auto Cut Off

2PCS DC 6-40V Battery Charger Discharger Control
1. Battery charge and discharge intelligent control;
2. You can set the charge and discharge time;
3. With serial communication function, real-time monitoring of the working status of the relay through the serial port;
4. Additional signal output, when the relay to meet the conditions, the output high, you can control other equipment.
5. A key emergency stop function (STOP button), with reverse protection, reverse does not burn.

Operating mode:
Voltage upper limit: UL1, voltage lower limit nL1, the voltage upper limit is greater than the voltage lower limit (UL1 Greater than nL1)
U-1: Charging measurement: When the measured voltage is lower than the lower limit voltage, the relay pulls above; the upper limit voltage, the relay is disconnected.
U-2: charge measurement time control: set the charging time (OP); when the measured voltage is lower than the lower limit voltage, the relay pull, and then start the countdown OP time, the end of the timer, the relay off; when the measured voltage is higher than the upper limit voltage , The relay is disconnected.
U-3: Discharge detection: When the measured voltage is lower than the lower limit voltage, the relay is off, above the upper limit voltage, the relay pulls;
U-4: discharge detection time control: set the discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay pull, and then start the countdown OP time, the end of the timer, the relay off; when the measured voltage below the lower limit voltage , The relay is disconnected;
U-5: voltage in the range, the relay pull: when the measured voltage between the upper and lower limits, the relay pull, the other circumstances open;
Colour:blue
Material:PC+Metal
