Import 5vdc 1a 5w Ac/Dc Power Adapter — Buy in wholesale FOB from Supplier in China

The 5VDC 1A 5W AC/DC power Adapter from Foshan Great Power Supply Co., Ltd. is a wall-mounted switching power supply designed for low-power electronics across multiple voltage markets. It accepts 100-240VAC at 50/60Hz through interchangeable plug systems (EU, AU, UK, and US options), with single-output DC regulation at 5V. The adapter employs a flyback or similar switching topology with 85% minimum efficiency and 200mV peak-to-peak ripple and noise specification. Protection features include over-voltage protection (OVP), short-circuit protection (SCP), over-current protection (OCP), and over-temperature protection (OTP). The housing uses PC/ABS thermoplastic with internal copper windings and a PCB with solid-state components.

The modular plug system allows a single SKU to serve multiple geographic markets without external adapters, reducing inventory complexity for distributors. The 5.5mm x 2.5mm or 5.5mm x 2.1mm DC jack is standard for CCTV and networking equipment, with cable lengths from 0.5 to 2 metres configurable at order. PC/ABS housing offers better heat resistance than pure ABS, with typical Vicat softening points of 110-130°C. The 2% output voltage accuracy claim indicates closed-loop regulation rather than simple transformer-based design. Standard 5W adapters in this category typically measure 50-70mm in length and weigh 80-150g depending on plug type and cable inclusion.

Primary applications include CCTV power supplies, network router and switch powering, small household appliances, and security device energisation. The CE marking and broad international approvals (GS, TUV, CCC, FCC, ROHS, PSE, CB, SAA mentioned) position this unit for global distribution. The supplier indicates OEM capability with 650,000 units monthly output across six production lines. Buyers should confirm the exact MOQ, lead time, and whether the quoted 2-year warranty applies to all export markets or selected regions. The interchangeable plug system and multiple DC jack options make this suitable for kit-based distribution models.
