8-CHANNEL POWER SUPPLY CCTV CAMERA DISTRIBUTION POWER SUPPLY BOX
DC 12V 20A 120W OUTPUT
MODEL: TX-07-120W-8CH
12V DC Centralized Power Supply Box (commonly models like TX-07-120W / TX-07 / TX-07 12V60W dual internal modules) designed primarily for CCTV camera installations, access control systems, and low-voltage LED/security setups.
-
Dual Module Architecture (2x 12V 60W Transformers):
-
Rather than using a single 120W switching circuit, this board features two isolated 12V 60W switching power supply modules on a shared PCB base.
-
This provides total power distribution up to 120W (10A overall output at 12V DC) while balancing line loads across separate primary transformers.
-
-
8 Channel (8-Port) Output Terminal Rail:
-
Features a row of screw terminals with PTC auto-reset fuses or individual glass fuse protection per channel for short-circuit and over-current protection.
-
-
Safety Shielding & Grounding:
-
Includes a clear acrylic protective shield over the high-voltage AC side to prevent accidental contact during live maintenance.
-
Integrated high-voltage input filter capacitor, line choke, and dedicated AC grounding connection directly attached to the metal enclosure frame.
-

Protection Mechanisms—Over-voltage, Over-current, Short-circuit protection, Thermal regulation
Enclosure-Wall-mount lockable metal cabinet with knockouts for conduit/cabling
Practical Usage & Wiring Guidance
-
CCTV Camera Networks: Provides centralized DC power for up to 8 analog/AHD/TVI/CCTV cameras, replacing individual wall adapters.
-
Access Control & Locks: Ideal for powering 12V door controllers, magnetic locks, keypad readers, and motion sensors.
-
LED Strip Lighting: Can feed up to 8 separate 12V DC low-voltage LED circuits or zone controllers.
Connection Steps:
-
AC Mains Input: Connect Live (L), Neutral (N), and Ground (Earth) to the AC input block located under the protective transparent guard.
-
DC Output: Connect each camera/device cable (+ and -) to one of the 8 pairs on the terminal strip.
-
Load Management: Keep total continuous current draw below 8A–8.5A (80% capacity rating) to maximize life span and prevent excessive heat buildup inside the metal cabinet.
