2. 安全に関する注意事項
Always adhere to the following safety precautions to prevent electric shock, fire, or damage to the device:
- Ensure the power supply is connected to a grounded outlet with the correct voltage (AC 230V).
- 濡れた状態や濡れた状態でデバイスを操作しないでください。amp 条件。
- cを開けないでくださいasing; 内部にはユーザーが修理可能な部品はありません。修理はすべて資格のある担当者にご依頼ください。
- 出力端子の短絡を避けてください。
- 適切な換気を確保し、換気口を塞がないようにしてください。
- Disconnect the power cord before cleaning or moving the unit.
- Use only the specified fuse type (F5A250VAC).

- デジタルディスプレイ： リアルタイム出力ボリュームを表示tage (V) と電流 (A)。
- 巻tage Adjustment Knobs (VOLT):
- 粗い： For large adjustments of output voltage.
- 罰金： For precise adjustments of output voltage.
- Current Adjustment Knobs (CURR):
- 粗い： For large adjustments of output current limit.
- 罰金： For precise adjustments of output current limit.
- CV（一定ボリュームtage) 指標: Illuminates when the unit is operating in constant voltageモード。
- CC（定電流）インジケーター： Illuminates when the unit is operating in constant current mode.
- 電源スイッチ： ユニットのオン/オフを切り替えます。
- 出力端子： Standard 4mm banana plug sockets for positive (red), negative (black), and ground (green/yellow) connections.
3.2 背面パネル
図3：詳細 view of the rear panel.
- 冷却ファン: Provides necessary airflow to dissipate heat.
- AC電源入力： IEC C14 connector for the power cord.
- ヒューズホルダー： Contains the main protective fuse (F5A250VAC).
4. セットアップ
- 開梱: Carefully remove the power supply from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future transport or storage.
- 配置: Place the unit on a stable, level surface. Ensure there is adequate space around the unit (at least 10 cm on all sides) for proper ventilation, especially around the rear cooling fan. Avoid placing it near heat sources or in direct sunlight.
- 電源接続: Connect the supplied AC power cord to the AC power input on the rear panel of the power supply and then to a grounded AC 230V wall outlet.
- 初期チェック: Before connecting any load, turn on the power supply using the front panel power switch. The digital display should illuminate, showing voltage と現在の測定値。
5. 操作手順
5.1 電源のオン/オフ
- To turn on, press the power switch on the front panel to the 'ON' (I) position.
- To turn off, press the power switch to the 'OFF' (O) position.
5.2 ボリュームの調整tageと現在
- 設定ボリュームtage: Rotate the 'VOLT Coarse' knob to set the approximate desired voltage. Use the 'VOLT Fine' knob for precise adjustments. Observe the voltage reading on the digital display.
- 電流制限の設定: Rotate the 'CURR Coarse' knob to set the approximate maximum current limit. Use the 'CURR Fine' knob for precise adjustments. This setting determines the maximum current the power supply will deliver before switching to Constant Current (C.C.) mode.
- CV/CC モードについて理解する:
- コンスタントボリュームtage (C.V.): When the load resistance is high enough that the current drawn is less than the set current limit, the power supply operates in C.V. mode, maintaining the set voltage. The C.V. indicator will be lit.
- Constant Current (C.C.): When the load resistance is low, causing the current drawn to reach the set current limit, the power supply switches to C.C. mode. The output voltage will drop to maintain the set current. The C.C. indicator will be lit.
5.3 負荷の接続
- Ensure the power supply is turned off before connecting any load.
- 負荷のプラス (+) 端子を電源の赤い出力端子に接続します。
- 負荷のマイナス（-）端子を電源の黒色の出力端子に接続します。
- If your load requires grounding, connect its ground terminal to the green/yellow output terminal of the power supply.
- After connecting the load, turn on the power supply. Adjust voltage and current as required for your application.
6. メンテナンス
- クリーニング： 清掃する前に、電源プラグをコンセントから抜いてください。表面は柔らかく乾いた布で拭いてください。研磨剤入りの洗剤や溶剤は使用しないでください。
- 換気： Regularly check that the ventilation openings and cooling fan are free from dust and debris. Use compressed air to clear any blockages if necessary.
- ヒューズの交換: If the unit fails to power on, the fuse may need replacement. Disconnect the power cord, locate the fuse holder on the rear panel, and replace the fuse with one of the identical type and rating (F5A250VAC).
- ストレージ： 長期間使用しない場合は、電源装置を直射日光や極端な温度を避け、涼しく乾燥した場所に保管してください。
7。 トラブルシューティング
| 問題 | 考えられる原因 | 解決 |
|---|---|---|
| ユニットの電源が入りません。 | コンセントから電源が供給されない、電源コードが緩んでいる、ヒューズが切れている。 | Check wall outlet; Ensure power cord is securely connected; Replace fuse (F5A250VAC). |
| 出力なしvoltage / current。 | 出力端子が接続されていません。Voltage/current knobs set to zero; Unit in C.C. mode with low current limit. | Verify load connections; Adjust voltage and current knobs; Increase current limit or check load resistance. |
