5. Setup

5.1 Physical Connection

Connect the input power source to the IN+ and IN- terminals on the bare board. Connect your load or battery to the OUT+ and OUT- terminals. Ensure correct polarity for all connections. If charging a battery, consider adding an anti-backflow diode to the output.

For MPPT solar charging, connect a solar panel to the input and an external temperature probe to the NTC temperature probe interface. The battery icon will be displayed on the screen once the battery is connected.

5.2 Communication Setup

The bare board supports serial communication and on-board 485 communication. These can be used simultaneously. For remote control via APP or web-based networking, connect a WiFi module to the serial port TTL level interface.

For low-cost multi-machine control, utilize the 485 bus control. Independent dual serial ports (serial port TTL and on-board 485) are available.

6. Operating Instructions

6.1 Basic Operation and Display

The device features a rotary encoder for quick and smooth page navigation. The main UI displays voltage, current, power, and set values. Other UIs include capacity record, voltage/current curve, parameter settings, system parameter settings, and pairing UI.

The display color can be customized with 8 color options to create a unique style.

6.2 Setting Voltage and Current

There are three ways to set voltage and current:

1. Quick Setup Mode:
   • Press the V-SET/I-SET button briefly to enter voltage/current setting mode.
   • Use the SW button or encoder button to move between digits.
   • Rotate the encoder to adjust the voltage/current value. Once set, press V-SET/I-SET briefly to save and exit.
2. Encoder Mode:
   • Press the encoder button briefly to activate the parameter (voltage/current) you want to set.
   • Press the encoder button to switch between full selection and digit selection. In full selection, all digits are highlighted. Rotate the encoder to switch between setting voltage or current. In digit selection, the selected digit is highlighted. Rotate the encoder to adjust the value.
   • To finish, either hold the encoder button/SW button for 2 seconds or wait 6 seconds without any button press. All settings are saved automatically.
3. Remote Control Mode:
   • Use an infrared remote control or 433M wireless remote control module to set voltage and current directly with the remote's numeric keypad.

6.3 CV CC CW Features

• Constant Voltage (CV): When the load current is less than the set constant current value, the power supply operates in constant voltage mode, where the output voltage is the set voltage value, and the current is adaptive.
• Constant Current (CC): When the load current is greater than the set constant current value, the power supply operates in constant current mode, where the output current is the set current value, and the voltage is adaptive.
• Constant Power (CW): After enabling the constant power function, the constant current value defaults to the maximum value. The constant voltage value serves as the initial voltage (set to a reasonable value based on actual conditions). After the power supply is turned on, the equivalent resistance R of the load is calculated using Ohm's law R=U/I. Then, the corresponding voltage can be calculated based on the set constant power value using the power formula P=U²/R. At this point, the constant power point algorithm automatically follows, and the constant power is achieved.
  • Constant Power Switch and Constant Power Value Setting:
    1. In the system parameter settings UI, select the CW option. Turn ON to enable constant power, and turn OFF to disable constant power.
    2. After enabling constant power, press ISET briefly on the main interface to modify the value of constant power.

6.4 Network Control and Group Control

The device supports LAN penetration for real-time communication and remote control via external networks. It also supports email notifications and cloud records. Control is possible through PC host computer software or the Sinilink mobile APP (Android/iOS).

The digital control panel supports one-to-many group control. By turning on the group control switch on the panel and using the 485 bus, you can collectively manage power supply activation/deactivation, voltage/current settings, achieving one-to-many control with simplicity and efficiency.

Activating Group Control Function: On the main power supply interface, briefly press the SW button to select the right status bar. Rotate the encoder to choose the group control switch activation icon, then briefly press the encoder button to open the selection dialog. Press the SW or encoder button to select and rotate the encoder to ON to enable group control mode. When setting voltage, current, or power on/off, the changes will automatically synchronize to all devices on the 485 bus (Note: Device addresses on the bus must be unique). Hold the SW button or wait 6 seconds without operation to exit and save settings automatically.

6.5 Universal Button Functions

Rotate the encoder to choose the data set you want. Then, either hold I-SET or briefly press the SW/encoder button to load the selected data set. The interface will show the currently loaded data set.
• Quickly Adjust System Parameters in the Status Bar: On the main screen, briefly press the SW button to select a status bar parameter. Rotate the encoder to switch between parameters. Briefly press the SW button 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.
