Long Description
The DH-PFM344D-20CH-BS provides a centralized and organized power solution for multi-camera surveillance installations. With 20 independent output channels, it can supply multiple compatible CCTV cameras and security devices from a single power unit, helping simplify installation and power distribution.
The unit accepts a 100–240VAC input and provides three selectable DC output levels: 12VDC (Normal), 13.5VDC (Long), and 15VDC (Ex-Long). This adjustable output allows the power supply to compensate for voltage drops over different cable distances. The unit provides up to 5A at 12VDC, with a maximum total rated output of 60W.
For improved system reliability, the power supply incorporates overcurrent, overvoltage, and short-circuit protection, along with surge protection of ±4kV common mode and ±2kV differential mode. It is housed in a compact gray enclosure and supports wall-mount installation, making it suitable for professional CCTV and security-system deployments.
