### Product Overview
XH-M609 Low Voltage Disconnect Switch is a reliable over-discharge protection solution for 12V, 24V, 36V lithium-ion batteries, equipped with a clear digital LED display for easy parameter checking and adjustment.
### Core Features
1. This programmable low voltage disconnect module is compatible with DC 12-36V lithium-ion batteries. *Note: This is a protection switch module only, batteries are not included in the package.*
2. Adjust low voltage disconnect parameters easily via the on-board momentary push buttons, all settings are clearly displayed on the 3-digit red LED screen for hassle-free operation.
3. The module automatically disconnects the load once the battery voltage drops to your preset value, effectively preventing battery over-discharge to greatly prolong your battery’s service life.
4. High 0.1V display and control accuracy ensures stable performance: the switch triggers quickly when voltage approaches the minimum threshold. All settings are stored in non-volatile memory, so they won’t be lost after power off.

### Operation Guide
1. Double-click the "+" button, then press "+" or "-" to set the cut-off voltage value.
2. Double-click the "-" button, then press "+" or "-" to set the recovery voltage value.
3. Single-click the "+" button first, then press "+" or "-" to calibrate the input voltage display.
4. Single-click the "-" button first, then press "+" or "-" to set the delayed start time T. When the input voltage reaches the start threshold, output will be activated after T minutes. Delay time ranges from 0 to 10 minutes, optional values are 000 / 001 / 005 / 010.
5. Single-click the "+" button to check the set cut-off voltage value.
6. Single-click the "-" button to check the set recovery voltage value.
7. The difference between cut-off voltage and recovery voltage can be set between 0.5V and 48V.
#### What is the difference value?
It refers to the gap between the battery cut-off voltage and the reconnection voltage.
*Example: If you want the battery to stop output when voltage drops below 11V, and resume output when voltage rises above 11.6V: Double-click "+" to set cut-off voltage to 11, wait for the LED to stop flashing, then double-click "-" to set the difference value to 0.6V.*
