Power Supply DAHUA PFM320-010EN 320W 12V – CCTV / Security Power Unit

The DAHUA PFM320-010EN 320W 12V is a dedicated power supply unit designed for CCTV and security installations that require stable 12V DC power. Compact and engineered for continuous operation, this unit delivers a regulated output to support multiple cameras and auxiliary devices in small to medium surveillance systems. Its form factor allows for rack or surface mounting, helping integrate power distribution into control rooms, network cabinets, or equipment racks while minimizing footprint.

Advantages

The power unit supplies a continuous 12V DC output with a total capacity of 320W, offering consistent voltage regulation to reduce flicker and operational interruptions for connected cameras and peripherals. Its compact chassis provides flexible installation options, and built-in protections against common electrical faults help safeguard both the power unit and connected devices. Designed for security environments, the unit supports stable, long-term operation required for 24/7 surveillance systems.

Suitable for

• Small and medium CCTV camera installations
• Security system control rooms and equipment cabinets
• Powering 12V DC cameras, IR illuminators, and auxiliary security devices
• Environments where rack or surface mounting is preferred

Key specifications

• Output voltage: 12V DC
• Total power capacity: 320W
• Form factor: compact chassis suitable for rack or surface mounting
• Output type: regulated DC supply for multiple devices
• Intended use: continuous operation for surveillance and security equipment
• Protection features: built-in safeguards against common electrical faults (overload/short-circuit/over-voltage protection)

How to use

Install the power supply in a well-ventilated area inside a cabinet or on a suitable flat surface, or mount it in a rack if rack-mounting options are available. Connect the unit to an appropriate mains source according to local electrical regulations and then distribute the 12V DC outputs to cameras and compatible devices using correct-gauge cabling. Verify polarity and connection points for each device before powering on. After initial connection, observe the unit during startup to confirm stable voltage output and proper operation of connected devices.

Usage recommendations

For reliable long-term performance, place the unit where ambient temperature and ventilation meet the manufacturer's environmental requirements, use adequately sized cables to minimize voltage drop across runs, and ensure regular visual inspections of connections and load distribution. When integrating into a surveillance system, plan the load per output channel to avoid overloading and consider centralising power for easier maintenance.
