30V 14A 420W Desktop Power Adapter with Active PFC for Industrial & Automation Systems | Guangdong QINX

Engineered for continuous high-power operation, the Guangdong QINX 30V 14A 420W desktop AC/DC power adapter integrates active Power Factor Correction (PFC) technology to improve conversion efficiency, lower harmonic distortion and enhance overall power quality. Its wide 100–240VAC input range allows the same model to be used in international markets with compatible regional AC power cords.

The power supply utilizes a high-efficiency switching circuit with precision voltage regulation to deliver a consistent 30V DC output under varying load conditions. Low ripple and excellent transient response help ensure reliable operation of sensitive electronic equipment, while the heavy-duty desktop enclosure and optimized airflow design promote efficient thermal management during long-term operation.

With a maximum output of 420W, this adapter is well suited for robotic automation systems, industrial PLC controllers, machine vision equipment, laser devices, communication infrastructure, intelligent inspection systems, LED display controllers, medical diagnostic equipment, semiconductor processing equipment and advanced manufacturing machinery.

Guangdong QINX offers flexible OEM and ODM manufacturing solutions, including customized output specifications, DC cable length, connector selection, housing color, logo printing, product labeling, packaging design and AC plug types for different countries.
