XH-M609 Low Voltage Disconnect Switch 12V 24V 36V Over-Discharge Protect for 12-36V Lipo Battery

XH-M609 Low Voltage Disconnect Switch Cut Off 12V 24V 36V Digital LED Display Over-Discharge Protect for 12-36V Lithium Battery

- Programmable battery low voltage disconnect switch for DC 12-36V lead acid battery and lithium ion battery. It's a protection switch module, not included batteries itself.
- On-board momentary push button to set the low voltage disconnect parameter and 3 digit red LED display the parameter easy to operation
- When the battery voltage reach the setting values, the module will disconnect load automatically to avoid the battery from over discharging to prolong the battery lifetime
- Display is accurate, the switch module is quickly to open and close when near minimum voltage; Settings is stored non-volatile, it can keep set when power off.

Specifications:
- Input Voltage Range: DC 12-36V
- Control Accuracy: 0.1V
- Compatible Battery: lead acid, lithium ion battery, solar panel battery
- Board Size: 57 X 42 X 19mm (L*W*H)

Operation Instructions:
1. Double-click the + number button, then press + or - button, set the stop voltage value
2. Double click on the-number button, then press + or - button, set the return voltage value
3. Press the + number button, then press + or - button, calibrate the input voltage display value
4. Press the - number button, then press + or - button, set the latency start value T. At the time of the output voltage reaches the start value, after the delay T, there is a voltage output, the delay time is 0 ~ 10 minutes, the display category is: 000 or 001 or 005 or 010
5. Click the + number button to view the stop voltage value
6. Click the - number button to view the return voltage value
7. The difference in the difference can be set to 48V, minimum can be set to 0.5V

What is the "difference value"?
The value between the battery voltage to disconnect and the battery voltage to reconnect.

For example
I want the battery to stop outputting when the battery voltage is lower than 11V and re-output when it is over 11.6V. What should I do?
Hold on "+" and set the value as 11. The LED starts flashing. After the flashing stops, hold on "-" and set the difference value as 0.6V.
