Factory Direct 29V 14.5A 420W Desktop Power Adapter with Active PFC & Optional DC Connectors | Guangdong QINX

Designed for demanding applications, the 29V 14.5A 420W desktop power adapter delivers a stable and regulated 29V DC output while providing sufficient current capacity for power-hungry equipment. Because the output power exceeds 200W and the output current exceeds 12.5A, Active PFC is incorporated to improve input power factor, reduce harmonic distortion and increase overall conversion efficiency.

The adapter accepts a universal 100-240VAC input, making it suitable for deployment in North America, Europe, Asia and other international markets. High-efficiency switching circuitry ensures precise voltage regulation, low ripple and excellent load response performance, helping connected equipment operate reliably even under continuous workloads.

Its robust desktop housing is designed for long service life and efficient thermal dissipation. Guangdong QINX also offers customized solutions including output cable lengths, connector styles, enclosure markings, private-label branding and retail packaging, making the adapter suitable for OEM manufacturers, industrial integrators and commercial equipment suppliers.
