3. Configuración
3.1 Instalación física
The module can be used as a bare board or integrated into an enclosure. Refer to the dimensions for proper fitting.
3.2 conexiones de cableado
Connect the input power source to the IN+ and IN- terminals. Connect your load to the OUT+ and OUT- terminals. Ensure all connections are secure and correct polarity is observed.
For MPPT solar charging, connect the solar panel to the input and a rechargeable battery to the output. Attach an external temperature probe to the battery for over-temperature protection. Flip the MPPT switch to ON.
The bare board version can be used independently and supports MPPT and analog 0.3-10V control, along with serial communication and on-board 485 communication.
The dip switch allows setting the constant current value, eliminating the need for a multimeter for current range measurement and preventing burnout. In potentiometer mode, constant voltage is controlled via potentiometer, and constant current via dip switch.

- Quickly Adjust System Parameters: On the main screen, briefly press the SW button to select a status bar parameter. Rotate the encoder to switch between parameters. Briefly press SW or encoder button to adjust the parameter or open the parameter setting interface. Use the encoder to set the value. To save and exit, either hold the SW button/encoder button or wait 6 seconds without any button press. All settings are saved automatically.
4.5 CC.CV.CW Features
The power supply supports Constant Voltage (CV), Constant Current (CC), and Constant Power (CW) modes.
- Constant Power Function (CW): When enabled, the power supply automatically switches between CV and CC based on the load. To enable/disable CW, navigate to the system parameter settings UI, select CW, and turn ON/OFF. After enabling, briefly press ISET on the main interface to modify the constant power value.
4.6 Communication and Remote Control
The module supports standard Modbus protocol for serial communication and features independent dual serial ports (TTL and on-board 485).
It can be controlled via a PC host computer, mobile APP (Sinilink control for Android/iOS), or remote control modules (infrared and 433M wireless).
The onboard 485 communication enables remote multi-machine control, and with multi-serial port PC software, functions are more powerful. Communication control can be achieved with a separate bare board for a low-cost solution.
