Professional 12V 20A Power Supply 240W CCTV Metal Box

CCTV Centralized Power Unit

The Professional 12V 20A Power Supply provides a reliable, centralized DC output for large-scale security camera installations. This hardware converts standard AC mains electricity into stabilized direct current. It maintains consistent voltage levels across all connected peripherals. The internal switch-mode power supply (SMPS) architecture ensures high efficiency during continuous operation. Consequently, it minimizes heat generation within the enclosure. This system supports multiple camera channels from a single source point.

Key Features

• Industrial Metal Enclosure
  The heavy-duty ventilated steel housing facilitates passive thermal management through airflow dissipation.

• Individual Circuit Protection
  Each output channel utilizes independent fusing to prevent total system failure during a single device fault.

• Protection Mechanisms

  • Auto-resetting PTC fuse technology for short-circuit protection
  • Over-voltage suppression to safeguard sensitive camera sensors
  • Overload protection prevents damage during peak current draw
