DC 12V-36V Battery Charge Discharge Voltage Monitor Voltage Over Discharge Protection Module

Description:

It is a DC 12V-36V Battery Charge Discharge Voltage Monitor. It can input voltage from DC 12V-36V Battery and the output voltage is same to input. It can set battery discharge voltage to prevent the battery from over-discharging and causing damage. The output voltage can continue to provide voltage to the load when the battery charging voltage rises to the allowable discharge value.Therefore, it can effectively protect the service life of the battery and make the use of the battery safer and more reliable.

Features:

1>.Real-time battery voltage monitoring

2>.Automatically cut off the load to protect the battery

3>.Automatically start the load when charging is completed

4>.Programmable battery stop value and start value

Instructions

• Double press the “+” button, and when the decimal point is flashing, press the “+” or “-" button to set the disconnect voltage.

• Double press the “-" button, and when the decimal point is flashing, press the “+” or “-" button to set the difference value.

• Long press the “+” button, and when the LED screen is flashing, press the “+” or “-" button to calibrate the input voltage.

• Long press the “-" button, and then press the “+” or “-" button to set the delay value T. That is to say, when the output voltage reaches the reconnect value, it will delay T minutes, the load reconnects. The delay time range from 000 to 010 minutes, and it displays like: 000 or 001 or 005 or 010. Note that no decimal point is displayed at this time.

• Press the “+” button to view disconnect voltage.

• Press the “-" button to view difference value.

*What is the "difference value"?

The value between the disconnect voltage and the reconnect voltage. That is to say, difference value = reconnect voltage - disconnect voltage

For example

1. How to set if I want it to stop outputting when the voltage is lower than 11V and start when the voltage is over 11.6V?

• Long press “+” and the LED starts flashing, press the “+” or “-" button to set the value as 11V. After the flashing stops, long press “-" and when the LED is flashing, press the “+” or “-" button to set the difference value as 0.6V.

2. how to set if I want it to stop outputting when the battery voltage is lower than 12.5V and when it is over 14.8V, it starts outputting after 2 minutes?

• Double press “+” button to set it as 12.5 and then double press “-" button to set the difference value as 2.3 (because 14.8V-12.5=2.3V). And then press and hold on the “-" button, set T=2.

Why it doesn’t has output when I first connect it?

For example, if the disconnect volt is 9V and the difference value is 5V, then:

1. When first connected, if the battery is lower than 9V, there will be no output;

2. When first connected, if the battery is higher than 9V but lower than 14V (9+5), there will be no output;

3. When first connected, if the battery is higher than 14V(the reconnect voltage), there will be output;

4. During use, the module will be disconnected when the voltage drops to 9V, and will be automatically reconnected when the battery is charged to 14V.
