YX850 5V-48V Power Failure Automatic Switching Standby Battery Module

YX850 5V-48V Power Failure Automatic Switching Standby Battery Module is an intelligent emergency power controller designed to ensure uninterrupted operation for your critical electronic devices. This versatile module automatically switches the power source to a standby battery when the primary DC power supply fails, providing a seamless transition that prevents system resets. Consequently, it acts as a miniature Uninterruptible Power Supply (UPS) for various DIY electronics and industrial equipment. Furthermore, the wide voltage compatibility range from 5V up to 48V allows it to support a broad array of battery types and power adapters. Therefore, you can rely on the YX850 to protect your data and maintain hardware stability during unexpected power outages.

Key Features:

• Automatic Seamless Switching: The module detects power loss instantly and switches to the backup battery without any manual intervention.
• Wide Voltage Range: Supports a broad input spectrum from 5V to 48V, making it compatible with most standard DC power systems.
• High Load Capacity: It manages current loads up to 10A, allowing it to power significant peripherals or multiple small devices simultaneously.
• LED Status Indicator: Features an on-board LED that illuminates when the device draws power from the primary adapter, offering clear visual diagnostics.
• Compact Integrated Design: The small PCB footprint simplifies installation within tight enclosures or custom project boxes.

Pinout and Wiring:

• DC+ / DC-: Connect your primary DC power adapter (e.g., 12V or 24V supply) to these terminals.
• BAT+ / BAT-: Connect your standby battery (must match the voltage of the primary DC supply) to these terminals.
• OUT+ / OUT-: Connect your load or device (e.g., router, camera, or controller) to these output terminals.
• Operating Logic: When the DC input is active, the module passes power to the output and charges/maintains the battery connection; however, it immediately engages the battery loop if the DC input drops below the threshold.
