►Main Functions:

1. AC to DC Power Conversion: Converts 100-240V AC power to stable low-voltage DC power required by the device's internal circuitry.

2. Battery Charging and Management: Intelligently charges and manages the built-in rechargeable battery, ensuring a seamless switch to battery power in case of AC power interruption, thus protecting data security.

3. Multiple Voltage Outputs: Provides various specific voltages required by the motherboard, ECG signal acquisition board, display backlight circuit, thermal printer, and other functional modules.

4. System Protection and Stability: Integrates multiple protection circuits to prevent malfunctions caused by abnormal voltage, power overload, or output short circuits, ensuring stable and safe operation of the entire device.

►Three-way Interface

This refers to the power board's physical connection, which typically integrates three key external/internal electrical interfaces for flexible power supply and system coordination:

1.High-current/control signal interface with the mainboard (MAIN BD), transmitting core operating power.

2.Charging and power supply interface with the battery pack (NKB-301V), supporting offline operation.

3.Connection to the keyboard control board (KEY BD / UT-24452) or other front-end user operation panels such as switches and indicator circuits, transmitting wake-up and control signals.

►Installation Steps:

1. Disconnect all power to the device.

2. Use a screwdriver to unscrew all screws on the back cover. Carefully open the cover, locate the power board, and disconnect all cables from it, paying attention to the connection positions of all cables. Carefully remove the old power board.

3. Take out the new power board and reinstall it in the original configuration, tightening all interfaces and cables.

4. After testing and confirming there are no problems, reinstall the back cover.
