The DH-PFM320S-50 is a professional-grade switching power supply designed to deliver stable 12VDC output for multiple CCTV cameras and devices. It supports a wide input voltage range (90–264Vac), making it suitable for regions with electrical fluctuations.
The unit provides 50W output power with a rated current of 4.2A, and allows DC voltage adjustment (±10%) between 10.8V and 13.2V, ensuring flexibility for different loads in field applications. Built with high reliability, it passes a 3-month high-temperature aging test, guaranteeing long-term performance.
It includes surge protection (±2000V line-to-ground, ±1000V line-to-line) and ESD protection (±6000V contact, ±8000V air). With compact dimensions (99 × 82 × 30 mm), wall or ceiling mount installation, and metallic silver finish, the DH-PFM320S-50 is ideal for professional surveillance environments.
