Dahua DH-PFM320S-50 12V 50W Switching Power Supply – CCTV and Security System Power Unit

PFM320S-50 is a 12V DC / 50W switching power supply designed for video surveillance systems and professional electronic equipment requiring stable, continuous power. Commonly used to power IP and analogue cameras, DVR/NVR units, and sensors in residential, commercial, and industrial security installations.

The regulated 12V DC output at up to 50W covers the power requirements of most surveillance cameras, including multi-device configurations fed from a single supply. Built-in overvoltage and overcurrent protection prevents damage to connected equipment during mains fluctuations, ensuring uninterrupted operation without manual intervention.

The compact form factor simplifies installation inside distribution boards, equipment enclosures, and technical spaces with limited room. Switching topology delivers higher energy efficiency compared to traditional linear supplies, reducing heat dissipation and power draw during continuous 24/7 operation.

Recommended for security system installers, AV integrators, and technical staff equipping surveillance installations across residential, commercial, and industrial sites. Suitable as a dedicated power source for cameras, DVR/NVR units, motion sensors, and other equipment with a 12V DC continuous power requirement.
