Factory Direct 20V 20A 400W Desktop Power Adapter with Active PFC and Optional DC Connectors | Guangdong QINX

The Guangdong QINX 20V 20A 400W desktop power adapter delivers a regulated 20V DC output with a continuous current of 20A, providing 400W of dependable power for equipment operating under demanding conditions. Built with advanced switching power technology, it offers precise voltage regulation, low ripple and noise, rapid transient response, and high conversion efficiency, helping ensure reliable operation of sensitive electronic systems.

To meet the requirements of high-power applications, this model incorporates active Power Factor Correction (PFC) technology. The active PFC circuit improves power factor, reduces harmonic distortion, enhances energy utilization, and contributes to stable AC input performance, making it suitable for continuous-duty industrial and commercial installations.

With a universal 100-240VAC, 50/60Hz input, the adapter supports worldwide operation without requiring different regional versions. Guangdong QINX also provides flexible OEM and ODM services, including customized DC connectors, output cables, cable lengths, enclosure colors, silk-screen printing, private branding, packaging, and tailored electrical specifications to satisfy specific project requirements.
