Regulated 12V DC Power Supply Unit with 9 Channels, Backup Battery, for Burglar Alarms, CCTV, and Access Control

Revised Content:

The uninterrupted power supply (UPS) battery backup function of this product can prevent unexpected power outages in CCTV systems. The seamless transition from AC to battery mode makes it an ideal choice for connecting digital video recorders (DVRs). It effectively addresses the issue of unstable AC input.

This power supply unit features a universal AC input range of 100-240VAC, 50-60Hz, and provides a regulated 12VDC low-voltage output, which can be adjusted from 12V to 15V using the built-in trimmer. Each output is individually protected by a PTC (Positive Temperature Coefficient) fuse and has a corresponding LED indicator.

The installation process is straightforward:

1. Mount the enclosure in a location that is sheltered from direct sunlight and protected from moisture.
2. Knock out the appropriate 22mm conduit holes for the input and output cables.
3. Turn the internal power switch to the "OFF" position.
4. Connect your camera cables to the individually protected 12VDC outputs, accessed through the terminal blocks marked "(+)" and "(-)" respectively.
5. Connect the battery using the battery charging cables, ensuring the positive and negative terminals are correctly aligned.
6. Secure the battery using the provided battery fixing mount.
7. Connect the AC mains voltage (100-240VAC) to the 3-pin IEC socket.
8. Turn the internal power switch to the "ON" position. The green LED on the front of the unit should now be illuminated.
9. Close the cover and secure it with the provided door lock and screws.

The key features of this product include:

1. LED indicators: Red for AC, Green for DC, and Yellow for battery.
2. Lockable enclosure.
3. Air vents for heat dissipation.
4. Voltage adjustment trimmer (12-15V).
5. Individual PTC fuses and LEDs for each DC output.
6. Low-voltage outputs accessed through terminal blocks, with positive (+12VDC) and negative (0VDC) markings.
7. Battery fixing mount.
8. Battery charging cable.
9. Prefabricated conduit holes for cable threading.
10. AC input: 3-pin IEC socket.
11. Wall-mounting holes.
