When the actual current exceeds the set current value, the power supply automatically switches to Constant Current (CC) mode to protect the circuit.
3.3 ボリュームの設定tageと現在
- を押す V ボリュームを入力するボタンtage setting mode. The voltagディスプレイ上の値が編集可能になります。
- 回転する 調整ノブ to change the desired voltage value. Press the knob to move between digits.
- を押す I button to enter current setting mode. The current value on the display will become editable.
- 回転する 調整ノブ to change the desired current value. Press the knob to move between digits.
- 希望のボリュームになったらtage and current limits are set, press the オン/オフ 出力を有効にするボタン。
3.4 Protection Functions (OVP, OCP)
The SPE6053 includes multiple protection features:
- オーバーボルtage 保護 (OVP): Prevents damage to the load by limiting the maximum output voltage。 を押します オーバーバイ button to set the overvoltage制限。
- 過電流保護（OCP）： Protects the load from excessive current. Press the OCCP button to set the overcurrent limit.
- 短絡保護: 短絡が発生した場合には自動的に出力をシャットダウンします。
- 過電力保護: Limits the total output power.
- 熱保護: ユニットを過熱から保護します。
It is recommended to set OVP and OCP values slightly above your desired operating voltage and current to provide a safety margin for your connected circuit.
3.5 メモリ機能
The power supply features 4 groups of memory parameters for quick recall of frequently used settings. Press the メモリ button to access these functions. Refer to the on-screen prompts for saving and recalling parameters.
3.6 USB Charging and PC Software Control
The front panel includes a 5V/1A USB output port for charging mobile phones or other compatible devices. Additionally, the rear USB communication port allows for firmware updates and control via PC software. This enables advanced programming and monitoring capabilities.
