4. సెటప్ మరియు ఇన్‌స్టాలేషన్

Proper installation is crucial for the safe and correct operation of the power supply board. Always ensure power is disconnected before making any connections.

4.1 భద్రతా జాగ్రత్తలు

• Ensure all power sources are disconnected before handling the board.
• Avoid touching components while the board is powered, as high voltages ఉండవచ్చు.
• Install the board in an enclosure that provides adequate ventilation and protection from environmental factors.
• Observe correct polarity for input and output connections.

4.2 కనెక్షన్ సూచనలు

Refer to the image below for input and output terminal identification.

Image 4.1: Close-up of the power supply board showing clearly labeled 'IN' for input and 'OUT' for output terminals. The input accepts AC 55V-277V or DC 70V-390V, and the output provides DC 12V.

1. ఇన్‌పుట్ కనెక్షన్: Connect your AC (55V-277V) or DC (70V-390V) power source to the terminals labeled 'IN'. Ensure correct polarity if using a DC input (L for positive, N for negative, though for AC it's line and neutral).
2. అవుట్‌పుట్ కనెక్షన్: Connect your 12V DC load to the terminals labeled 'OUT'. Observe the '+' and '-' markings for correct polarity.
3. ధృవీకరణ: పవర్ వర్తించే ముందు అన్ని కనెక్షన్‌లను ఒకటికి రెండుసార్లు తనిఖీ చేయండి.

5. ఆపరేటింగ్ సూచనలు

Once properly installed and connected, the power supply board operates automatically.

• Apply the specified input voltage (AC 55V-277V or DC 70V-390V) to the 'IN' terminals.
• The board will convert the input to a stable 12V DC output.
• An output indicator (red light) will illuminate when the output is active, indicating the presence of 12V DC.
• Ensure the total current drawn by your load does not exceed the maximum output current of 300mA to prevent damage to the board or connected devices.

6. నిర్వహణ

The AC-DC Isolated Switching Power Supply Board is designed for minimal maintenance. However, observing the following guidelines can help ensure its longevity:

• పర్యావరణ పరిస్థితులు: Operate the board within its specified working temperature range (-20°C to +70°C). Avoid exposure to excessive moisture, dust, or corrosive environments.
• శుభ్రపరచడం: If necessary, gently clean the board with a soft, dry brush or compressed air to remove dust. Ensure the board is powered off and disconnected from all sources before cleaning. Do not use liquids.
• తనిఖీ: Periodically inspect connections for tightness and signs of wear or corrosion.

7. ట్రబుల్షూటింగ్

If you encounter issues with the power supply board, consider the following troubleshooting steps:

• అవుట్‌పుట్ వాల్యూమ్ లేదుtage / Output Indicator Off:
  • Check if the input power source is correctly connected and supplying the specified voltagఇ పరిధి.
  • Verify that the input terminals are correctly wired (L and N for AC, + and - for DC).
  • Ensure there are no short circuits on the output terminals.
• తప్పు అవుట్‌పుట్ వాల్యూమ్tage:
  • Confirm that the load connected is within the 12V DC specification and does not exceed the 300mA maximum current.
  • ఏవైనా వదులుగా ఉన్న కనెక్షన్లు లేదా దెబ్బతిన్న వైరింగ్ కోసం తనిఖీ చేయండి.
• వేడెక్కడం:
  • బోర్డు చుట్టూ తగినంత వెంటిలేషన్ ఉండేలా చూసుకోండి.
  • Verify that the output current does not exceed 300mA.
  • Reduce the ambient temperature if it exceeds the maximum operating temperature.
• అడపాదడపా ఆపరేషన్:
  • Inspect for loose connections or intermittent shorts.
  • Check for unstable input voltage.

If problems persist after following these steps, discontinue use and consult a qualified electronics technician.
