Pack of 2 Airflow Cabinet Fans 12V DC for Security and Network Cabinet Cooling

12V DC fans are the correct specification for security and CCTV equipment cabinets where the power supply inside the cabinet is a 12V DC PSU rather than a mains-connected PDU. Alarm panels, DVR power supplies, and CCTV PSUs all produce a 12V DC output, which these fans can be connected to directly.

In a security installation in a small wall cabinet where the only power in the cabinet is 12V from the alarm or CCTV power supply, 240V AC fans would require a separate mains outlet inside the cabinet, adding cost and wiring complexity. The 12V DC fans run directly from the available low-voltage supply.

Fan function and installation position are identical to the 240V variant: the fans are installed in the top of the cabinet to draw air upward through the equipment, maintaining operating temperatures within safe limits.

The distinction from the 240V AC fans (Cabinet FAN-240V) is the power supply requirement: 12V DC fans require a 12V DC source; 240V AC fans require a mains connection. The correct choice depends on what power is available inside the specific cabinet installation.
