4.コンポーネントの識別

図4.1: Front panel controls and indicators. The 'SW' key switches display modes, 'U/I' key selects voltage/current adjustment, 'CC' indicates constant current mode, 'ON' indicates output enabled, and the rotary encoder adjusts values.

図4.2: Internal components and connection points. The input terminals are labeled IN+ and IN-, while the output terminals are OUT+ and OUT-. The fan and heat sink are visible for thermal management.

5. セットアップ手順

1. 電源を切る： 接続を行う前に、すべての電源が切断されていることを確認してください。
2. 入力接続: Connect your DC power source (6.0V-36V) to the イン+ そして で- terminals. Observe polarity: イン+ for positive, で- for negative. The module has reverse polarity protection, but correct wiring is always recommended.
3. 出力接続: 負荷を アウト+ そして 外- terminals. Observe polarity: アウト+ for positive, 外- for negative.
4. 安全な接続: Ensure all wire connections are tight and secure to prevent loose contacts and potential damage.
5. 初回電源オン: After verifying all connections, apply power to the input. The LCD display should illuminate.

6. 操作手順

6.1. 表示モード

• を押す SW key to cycle through different display modes: input voltage、出力ボリュームtage, output current, output power, output capacity (Ah), and output time (h).
• The display will show 'IN' for input parameters and 'OUT' for output parameters.

6.2. 出力ボリュームの調整tageと現在

1. 巻tage 調整: を押す ユ・アイ key until the voltage value on the display starts blinking. Rotate the rotary encoder clockwise to increase the voltage and counter-clockwise to decrease it. Press ユ・アイ again to confirm the setting or wait a few seconds for it to auto-confirm.
2. 電流制限調整: を押す ユ・アイ key until the current value on the display starts blinking. Rotate the rotary encoder to set the desired current limit. Press ユ・アイ again to confirm. The 'CC' indicator will light up when the module operates in constant current mode.

6.3. Output Enable/Disable

• を押す オン/オフ button (often integrated with the rotary encoder or a separate button) to enable or disable the output. The 'ON' indicator light will show the output status.

7. 保護メカニズム

The module incorporates several software protection features with adjustable thresholds. If any operating parameter exceeds its set threshold, the output will automatically be disabled to protect the module and the connected load.

• 入力逆接続防止保護: 誤った入力極性による損傷を防止します。
• Output Anti-Reverse Protection: Protects the module if a reverse voltage is applied to the output.
• 入力アンダーボリュームtage プロテクション (UVP): Adjustable from 5.8V to 36V (default 5.8V).
• 出力オーバーボリュームtage 保護 (OVP): Adjustable from 0.6V to 36V (default 36V).
• 出力過電流保護（OCP）： Adjustable from 0A to 5A (default 5A).
• 出力過電力保護（OPP）： Adjustable from 0W to 80W (default 80W).
• 過熱保護（OTP）： Adjustable from 80°C to 110°C (default 110°C).
• Timed Protection (OHP): Adjustable from 0 to 100 hours (default off).
• Overcapacity Protection (OAP): Adjustable from 0 to 60Ah (default off).

To adjust protection thresholds, refer to the detailed instructions provided with the product packaging or manufacturer's website, as the exact button sequence may vary slightly.

8. メンテナンス

• クリーニング： Keep the module clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquids or abrasive cleaners.
• 換気： Ensure the fan and ventilation openings are not obstructed to maintain proper airflow and cooling. Periodically check for dust buildup on the fan blades and heat sink.
• ストレージ： Store the module in a dry, cool environment away from direct sunlight and extreme temperatures.
• 接続: すべての電気接続部の締め付け具合や摩耗、腐食の兆候がないか定期的に確認してください。

9。 トラブルシューティング

• ディスプレイなし/電源なし:
  • 入力電源と接続を確認してください。入力電圧がtageは6.0V〜36Vの範囲内です。
  • 入力極性が正しいことを確認してください。
• 出力なし:
  • Ensure the output is enabled (check 'ON' indicator).
  • Check for active protection (e.g., OVP, OCP, OTP indicators). If a protection is triggered, the output will be disabled. Address the cause (e.g., reduce load, check temperature) and re-enable output.
  • 出力接続と負荷を確認します。
• 出力巻tage/Current Not Stable:
  • Ensure input power is stable and sufficient for the desired output.
  • 接続が緩んでいないか確認してください。
  • If operating near maximum power (80W) or current (5A), ensure adequate cooling. The intelligent fan should activate.
• ファンが動作していない:
  • The fan is temperature-controlled. It will only activate if the internal temperature exceeds 50°C or the output current exceeds 1A. This is normal operation.
  • If the module is hot and current is high, but the fan is not running, check for obstructions or fan malfunction.
