4 製品の特徴

• 自動電力計算: Unlike other DC power supplies, the WANPTEK DPS305U automatically calculates the power value. It simultaneously displays voltage, current, and power values with a precision of 0.01V, 0.001A, and 0.001W.
• 5V / 3.6A USB Interface: Equipped with a high-speed charging protocol identification chip, this variable power supply supports USB fast charging. It provides a 5V / 3.6A output, allowing for quick charging of mobile phones and other devices, or for powering devices under repair.
• 短絡警報: Designed to enhance safety and extend the lifespan of the DC power supply. When a short circuit occurs, the adjustable DC power supply unit stops output and emits an alarm. The bench power supply includes safety protections such as over-voltage, over-current, over-temperature, and overload protection.
• 幅広い用途: This adjustable power supply features an electrically controlled fan and an excellent heat sink for efficient heat dissipation. It is particularly suitable for laboratories, electronic repair DIY, communication equipment maintenance, product lines, scientific research, and educational units.
• 高精度: The power supply boasts a high resolution of 0.01V and 0.001A, ensuring accurate and stable output.

   • Connect the black output power cord (alligator clip) to the Negative Terminal (-).
   • If grounding is required for your application, connect a separate ground wire to the GND terminal.
5. 初期チェック: Before connecting any load, ensure all knobs (V-COARSE, V-FINE, A-COARSE, A-FINE) are turned fully counter-clockwise to their minimum settings.

7. 操作手順

7.1 基本操作

1. 電源オン: Flip the Power On/Off switch to the "ON" position. The display will light up.
2. ボリュームの調整tage（Constant Voltage Mode - CV):
   • Turn the V-COARSE knob clockwise to set the approximate desired voltage.
   • Use the V-FINE knob to precisely adjust the voltage to the exact desired value.
   • The "C.V" indicator on the display will light up when the unit is operating in Constant Voltageモード。
3. Adjusting Current Limit (Constant Current Mode - CC):
   • To set the current limit, first short-circuit the output terminals (connect the red and black alligator clips together). The "C.C" indicator will light up.
   • Turn the A-COARSE knob clockwise to set the approximate desired current limit.
   • Use the A-FINE knob to precisely adjust the current limit.
   • Remove the short circuit from the output terminals. The unit will return to Constant Voltage mode if no load is connected or if the load draws less current than the set limit.
   • The "C.C" indicator will light up when the unit is operating in Constant Current mode (i.e., the load is drawing the maximum set current).
4. 接続負荷: 希望の音量を設定した後tage and current limits, connect your device or circuit to the output terminals. Ensure correct polarity.
5. 監視： Observe the display for real-time voltage、電流、および電力の読み取り値。

8. メンテナンス

• クリーニング： Disconnect the power supply from the main power outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
• 換気： Ensure the cooling fan and vents are free from dust and obstructions. Periodically check for dust buildup and gently clean with compressed air if necessary.
• 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。
• ヒューズの交換: If the unit does not power on, check the fuse located in the fuse box on the rear panel. Replace it only with a fuse of the same type and rating. Refer to the specifications for fuse details.
