1. Introduction
The TARSHYRY YX851 is a DC 12V 10A Automatic Power Switching Module designed to provide uninterrupted power to a load by seamlessly switching between a main power supply and a backup battery. This module prioritizes the main power supply and automatically transitions to battery power during outages, ensuring continuous operation of your connected devices. Its advanced manufacturing technology guarantees high reliability and stable performance, meeting strict quality standards for dependable use.

2. Setup and Wiring
Proper wiring is crucial for the safe and effective operation of the YX851 module. Refer to the wiring diagram below for connection details. Ensure all connections are secure before applying power.
Figure 2: Wiring diagram for the YX851 module. Connect the 12V power supply, 12V battery, and load as shown.
Connection Steps:
- Main Power Supply Connection: Connect your 12V main power supply (e.g., a 12V power adapter) to the designated input terminals on the module. Ensure correct polarity (+ and -).
- Battery Connection: Connect your 12V backup battery to the battery terminals on the module. Observe correct polarity (+ and -). The module will charge the battery when the main power is present.
- Load Connection: Connect your DC 12V load (the device you want to power) to the output terminals. Ensure correct polarity.
- Voltage Adjustment: Before initial use, adjust the charge start and shutdown voltage settings as described in the Operating Instructions section to match your battery type and desired operation.
3. Operating Instructions
The YX851 module operates automatically to manage power distribution. It features user-friendly voltage adjustments for precise control over battery charging and switching thresholds.
Automatic Switching Function:
- When the main 12V power supply is active, the module prioritizes power delivery to the load from the main supply and simultaneously charges the connected 12V battery.
- In the event of a main power failure, the module automatically switches the load to the backup 12V battery, ensuring continuous power without interruption.
- When the main power supply is restored, the module automatically switches the load back to the main supply and resumes charging the battery.
Voltage Regulation:
The module includes two potentiometers for voltage adjustment, allowing customization for various power and battery needs. These adjustments control the battery charging and discharge thresholds.
Figure 3: YX851 module showing locations for charge start and charge shutdown voltage adjustments.
- Charge Start Voltage Adjustment: This potentiometer controls the voltage level at which the module begins charging the battery. Turning clockwise increases the voltage, and counter-clockwise decreases it.
- Charge Shutdown Voltage Regulation: This potentiometer sets the voltage level at which the module stops charging the battery (or switches to battery power if the main supply drops below this threshold). Turning clockwise increases the voltage, and counter-clockwise decreases it.
Precautions for Voltage Adjustment: For 12V batteries, adjust a half circle clockwise to add approximately 0.5V, and a half circle counter-clockwise to subtract approximately 0.5V. Do not adjust more than one full circle to avoid damage or incorrect operation.
4. Maintenance
To ensure the longevity and optimal performance of your YX851 module, follow these simple maintenance guidelines:
- Keep Clean: Regularly clean the module with a soft, dry cloth to remove dust and debris. Avoid using liquids or abrasive cleaners.
- Check Connections: Periodically inspect all wiring connections to ensure they are tight and free from corrosion. Loose connections can lead to intermittent operation or damage.
- Environmental Conditions: Operate the module within its specified temperature and humidity ranges. Avoid exposing it to extreme heat, cold, or moisture.
- Ventilation: Ensure adequate airflow around the module to prevent overheating, especially during prolonged operation or high current draw.
