Dahua 12V DC / 2A Camera Plug Pack

The Dahua PFM320S-50 is a 12VDC, 50W switching power supply built to power multiple CCTV cameras from a single unit rather than one camera per adapter. It accepts a wide 90–264VAC input range to handle electrical fluctuation across different regions, delivers a rated 4.2A output, and allows the output voltage to be fine-tuned ±10% (10.8–13.2VDC) to match different camera loads via adjustable output resistance. Rated for –20°C to +50°C operation (with reduced 60% output up to +70°C), it mounts to a wall or ceiling in a compact metal enclosure. Built-in surge and ESD protection, plus a 3-month high-temperature aging test during manufacturing, are aimed at reliability in continuous-duty installations.
