Factory Direct 16V 25A 400W Desktop Power Adapter with Active PFC & Custom DC Connectors | Guangdong QINX

The Guangdong QINX 16V 25A desktop power adapter delivers a regulated 16V DC output with 25A continuous current, supplying 400W continuous power for high-current electronic devices operating in demanding industrial and commercial environments.

Since the output power exceeds 200W, this model adopts Active Power Factor Correction (Active PFC) technology to improve input power factor, reduce total harmonic distortion (THD), increase conversion efficiency, and minimize energy loss. The advanced PFC architecture helps ensure stable electrical performance while meeting international energy-efficiency and EMC requirements.

Designed with a 100–240VAC universal input, the adapter automatically supports worldwide AC power standards, making it suitable for products distributed across global markets. Its robust desktop enclosure utilizes an optimized thermal management system with efficient heat dissipation, enabling reliable full-load operation and extending product service life.

Guangdong QINX offers complete OEM and ODM customization, including output cable length, private labeling, enclosure color, packaging, connector selection, and electrical specifications. Optional DC connector configurations include 5.5×2.1mm, 5.5×2.5mm, 6.5×4.4mm, GX16, GX20, GX25 aviation connectors, M12/M16 waterproof connectors, XT60, XT90, Anderson SB50/SB120 connectors, Hirose circular connectors, Molex Mega-Fit connectors, Power DIN connectors, Weipu SP series connectors, Amphenol industrial connectors, and other custom cable assemblies tailored to customer requirements.
