Setup u Installazzjoni
1. Konnessjonijiet tal-Wiring
- Connect your DC input power source (6-70V) to the Input Positive (+) u Input Negative (-) terminali.
- Connect your load to the Output Positive (+) u Output Negative (-) terminali.
- Ensure all connections are secure and correct before applying power.
2. DIP Switch Settings for Fixed Output Voltage
The module features DIP switches for setting specific fixed output voltages when used as a standalone board. This is useful for applications requiring a constant, predefined voltage without digital adjustment.
Immaġni: DIP Switch Settings. This diagram illustrates how to configure the DIP switches to achieve fixed output voltages such as 5V, 9V, 12V, 24V, 36V, 48V, and 60V. 'NC' refers to the digital control stage, which should be matched when adjusting digital control.
Refer to the diagram above to set the desired fixed output voltage. Ensure the module is powered off before changing DIP switch settings.
Istruzzjonijiet Operattivi
1. Power On/Off
- Toggle the power switch to turn the module ON or OFF.
2. Aġġusta tal-Output Voltage u Kurrenti
- Use the encoder button (rotary knob) to adjust the output voltage and current. Rotate clockwise to increase, counter-clockwise to decrease.
- Press the encoder button briefly to switch between adjusting voltage u kurrenti.
3. LCD Display Modes
The LCD provides real-time monitoring of various parameters.
Immaġni: Multimeter Display. This image shows the LCD display in various states: when power is ON, displaying constant voltage (CV) mode with output voltage and current; when the encoder button is short-pressed, cycling through power (W), capacity (AH), energy (WH), and time (H); and when power is OFF, sequentially displaying the set voltage u kurrenti.
- When Power is ON: The display shows output voltage and output current. It also indicates Constant Voltage (CV) or Constant Current (CC) mode.
- Short Press Encoder Button: On the operating screen, a short press of the encoder button will cycle through displaying Power (W), Capacity (AH), Energy (WH), and Time (H).
- When Power is OFF: The display will sequentially show the previously set voltagvaluri e u kurrenti.
