1. The XH-M350 Backup Battery Switching Module is designed to manage the charging and switching between a primary power source and a backup battery.
2. 2 This ensures continuous power to your devices in case of a primary power failure. Here’s how to use it:
3. This module is for storage battery emergency switch.
4. It adopts the high quality industrial relay and the effective control current can reach 12A. In control of 12V, power can reach 150W. It is widely used in incubators, computers, networks and so on.
Components and Pinouts
1. DC Input Terminals (IN+ and IN-):
○ For connecting the primary power source (e.g., a DC adapter).
2. Battery Terminals (BAT+ and BAT-):
○ For connecting the backup battery.
3. Output Terminals (OUT+ and OUT-):
○ For connecting the load (the device you want to power).
4. Status LEDs:
○ Indicate the charging state and power source status.
Basic Usage
1. Connect the Primary Power Source:
○ Connect the positive terminal of the DC adapter to IN+ and the negative terminal to IN-.
2. Connect the Backup Battery:
○ Connect the positive terminal of the battery to BAT+ and the negative terminal to BAT-.
○ Ensure the battery is compatible with the module’s specifications (voltage and capacity).
3. Connect the Load:
○ Connect the device you want to power to the output terminals (OUT+ and OUT-).
4. Power On:
○ When the primary power source is available, the module will provide power to the load and charge the backup battery simultaneously.
○ If the primary power source fails, the module will automatically switch to the backup battery to ensure uninterrupted power to the load.
Monitoring and Adjustment
● Status LEDs:
○ The LEDs will show the charging status of the battery and indicate whether the primary power source or the backup battery is currently supplying power.
Safety Considerations
● Correct Polarity:
○ Always ensure that connections are made with the correct polarity to avoid damage to the module and connected devices.
● Input Voltage:
○ Ensure that the input voltage from the primary power source is within the module’s specified range.
Troubleshooting Tips
● LED Indicators:
○ If the LEDs do not light up, check the connections and ensure that the power source and battery are properly connected and functional.
● Battery Not Charging:
○ Verify that the primary power source is providing the correct voltage and current.
○ Check the battery connections and ensure that the battery is not faulty.
