19V 11A 209W Desktop Power Adapter with PFC | OEM Power Supply Manufacturer

The Guangdong QINX 19V 11A 209W desktop power adapter is designed to provide a continuous and regulated 19V DC output for equipment operating under demanding workloads. Since the output power exceeds 200W, the adapter incorporates active Power Factor Correction (PFC) technology, helping improve power conversion efficiency, reduce input current harmonics, and enhance overall energy utilization.

Built with premium switching components and high-reliability circuitry, the adapter offers excellent voltage regulation, low ripple characteristics, and stable performance during long-term continuous operation. Its universal 100-240VAC input enables deployment in global markets without requiring input voltage selection.

To satisfy diverse OEM requirements, Guangdong QINX provides extensive customization services, including DC output cable specifications, connector styles, cable lengths, enclosure appearance, company logo printing, product labels, packaging, and private-brand manufacturing. These flexible solutions make the adapter suitable for equipment manufacturers, system integrators, and industrial automation projects.
