Import Desktop Ac Dc Adapter — Buy in Bulk from Supplier in China

This desktop AC-DC adapter delivers dual output voltages: 12V at 2A and 5V at 2A, providing a total rated output power of 34W. It accepts input from 90VAC to 264VAC, making it suitable for global use with 50/60Hz frequency. The unit is designed for powering hard disk drives and other low-voltage industrial electronics requiring stable dual-rail power. Input current is limited to 1.0A maximum under full load.

The adapter achieves a minimum efficiency of 80% under standard operating conditions and includes protection circuits for over-current, over-voltage, short-circuit, and over-power conditions. Output ripple and noise are capped at 1% maximum, ensuring clean power delivery to sensitive components. The casing is constructed from flame-retardant polycarbonate, and internal components are conformal-coated for humidity resistance. These specifications align with standard industrial-grade desktop power supplies used in surveillance and embedded systems.

Buyers include manufacturers of security DVR systems, network-attached storage devices, and industrial automation controllers in Europe, North America, and Latin America. The adapter is typically integrated into end products as a component, not sold as a standalone retail item. Packaging is bulk polybag with anti-static lining. Lead time is 10 to 15 days after order confirmation. MOQ is 100 units. Buyers should request test reports for output stability under varying load conditions before bulk procurement.
