4. セットアップとインストール
Proper installation is crucial for the safe and effective operation of your laser power supply. Always ensure the power supply is disconnected from the main power source before performing any wiring or installation procedures.
4.1 配線図
Refer to the following diagram for correct wiring connections. Ensure all connections are secure and properly insulated.

Figure 4.1: Main wiring diagram showing input power, control signals, and laser output connections.
- AC Input (L, N, FG): Connect your 220V AC power source to these terminals. FG is for Frame Ground.
- ハイボリュームtage Output (LASER): ハイボリュームを接続するtage output to your CO2 laser tube. This connection carries high voltage and must be handled with extreme caution.
- Control Signals (H, L, P, G, IN, 5V): These terminals are for connecting to your laser controller board.
- H (Switch Laser Control Active High): For laser control via high-level signal.
- L (Switch Laser Control Active Low): For laser control via low-level signal.
- P (Water Protection): Connect to your water protection sensor. The laser will not fire if water flow is not detected.
- G (Signal Ground): 制御信号の共通基盤。
- IN (Input Control Signal 0-5V): For analog power control (0-5V).
- 5V (Output Power 5V): Provides 5V output for external devices.
- For Laser Signal Input: Typically an RJ45 port for specific controller connections.
4.2 External Ammeter Connection
The power supply supports an external ammeter for real-time current monitoring. Connect the ammeter as shown below.

Figure 4.2: Connection of the external ammeter to the power supply's dedicated port.
The external ammeter provides a digital display for current output and status indicators for water protection and laser signal. The trimmer potentiometer on the ammeter allows for fine-tuning of the current.

5. 操作手順
5.1 電源のオン/オフ
- 電源を入れる前に、すべての接続が正しく安全であることを確認してください。
- Turn on the main power switch to the laser machine. The power supply will initialize.
- To power off, turn off the main power switch.
5.2 Laser Test Function
The power supply includes a "TEST" button for manually checking the laser output. This is useful for troubleshooting or initial setup.
- Locate the red "TEST" button on the power supply unit.
- Press and hold the button to activate the laser output. The laser will fire at a low power setting.
- Release the button to stop the laser output.
- 注意: Never look directly into the laser beam. Always wear appropriate laser safety glasses when performing this test.
5.3 電流調整
The laser output current can be adjusted using the trimmer potentiometer on the external ammeter. Rotate the knob to increase or decrease the current as needed for your application. Monitor the current display on the ammeter during adjustment.
5.4 安全機能
- TTL Level Start/Stop: Allows for precise control of laser firing via digital signals from your controller.
- Output Open Circuit Protection: Protects the power supply from damage if the laser tube connection is interrupted.
- Water Through Signal Indication: The power supply will not allow the laser to fire if the water cooling system is not functioning correctly, indicated by the water protection status on the ammeter.
- Laser Output Indication: Provides visual feedback when the laser is actively firing.
6. メンテナンス
Regular maintenance ensures the longevity and optimal performance of your Cloudray Laser Power Supply.
- 清潔に保ちます: Periodically clean the exterior of the power supply, especially the fan vents, to ensure proper airflow and prevent overheating. Use a soft, dry cloth.
- 接続を確認してください: Regularly inspect all wiring connections (AC input, laser output, control signals) to ensure they are tight and free from corrosion or damage.
- 環境条件: Ensure the power supply operates within the specified environmental temperature range (-30°C to +65°C) and humidity levels.
- ファン操作: Verify that the cooling fan is operating freely and quietly. A noisy or non-functioning fan may indicate a problem.
