Figure 4.1: HI-FOCUS HF-PSF108 Power Supply Front View. This image shows the top panel of the power supply unit, displaying the model number (HF-PSF108), input voltage range (90-285V DC, 50-60Hz), output specifications (DC 12V-1A per channel), a voltage adjustment switch with 'Ex. Long', 'Long', and 'Normal' settings, and eight pairs of output terminals.
4.1 Key Components
- Input Terminals: For connecting the main AC power source (90-285V AC, 50-60Hz).
- Output Terminals: Eight pairs of terminals for connecting up to eight CCTV cameras (12V DC, 1A per channel).
- Voltage Adjustment Switch: Allows selection of output voltage compensation for different cable lengths ('Normal', 'Long', 'Ex. Long').
- Ventilation Grille: Ensures proper heat dissipation.
- Individual Power LED Indicators: Each output channel may have an LED to indicate power status.
- Resettable Fuses: Each channel is protected by a resettable fuse against overload and short circuits.
5. Setup and Installation
Follow these steps for proper installation of your HI-FOCUS HF-PSF108 power supply.
5.1 Mounting the Unit
- Choose a secure, dry, and well-ventilated location for mounting.
- Ensure there is sufficient space around the unit for heat dissipation and cable management.
- Mount the unit using appropriate screws and anchors suitable for the mounting surface.
5.2 Connecting Power Input
- WARNING: Ensure the main power source is OFF before connecting.
- Connect the AC power cable to the input terminals of the power supply. Refer to the unit's labeling for correct polarity (Live, Neutral, Ground).
- Ensure all connections are secure to prevent loose contacts and potential hazards.
5.3 Connecting CCTV Cameras
- Connect each CCTV camera's power input cable to one of the 8 output terminal pairs on the power supply.
- Observe correct polarity: connect the positive (+) wire of the camera to the positive (+) terminal of the power supply, and the negative (-) wire to the negative (-) terminal.
- Ensure all connections are tight and secure.
5.4 Voltage Adjustment Switch
The unit features a voltage adjustment switch to compensate for voltage drop over long cable runs. Select the appropriate setting based on your cable length:
- Normal: For standard cable lengths.
- Long: For moderately long cable runs.
- Ex. Long: For very long cable runs to ensure cameras receive sufficient voltage.
Adjust this switch before powering on the unit. Incorrect settings may lead to camera malfunction or reduced lifespan.
6. Operating Instructions
After completing the installation and verifying all connections:
- Turn on the main power supply to the unit.
- Observe the individual power LED indicators (if present) for each channel. A lit LED indicates that the channel is receiving power.
- Verify that all connected CCTV cameras are receiving power and operating correctly.
7. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your power supply unit.
- Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation grilles are free from dust and debris.
- Connection Check: Periodically inspect all power input and output connections to ensure they remain secure.
- Environmental Check: Ensure the operating environment remains within the recommended conditions (temperature, humidity).
- Fuse Reset: If a channel stops providing power, check the corresponding resettable fuse. Disconnect the camera from that channel, wait a few moments for the fuse to reset, then reconnect the camera. If the issue persists, troubleshoot the camera or cable.
8. Troubleshooting
If you encounter issues with your HI-FOCUS HF-PSF108 power supply, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to cameras | Main power disconnected Faulty input cable Internal fault | Check main power switch and connections Replace input cable Contact technical support |
| One camera not receiving power | Loose connection Tripped resettable fuse Faulty camera/cable | Check camera power connection Disconnect camera, wait for fuse reset, reconnect Test camera/cable with another power source |
| Cameras flickering or unstable video | Incorrect voltage adjustment Excessive cable length Overloaded channel | Adjust voltage switch to 'Long' or 'Ex. Long' Reduce cable length or use thicker gauge cable Ensure camera current draw is within 1A per channel |
| Unit overheating | Poor ventilation Overload | Ensure adequate airflow around the unit Reduce the load on the power supply |
