Import 300w Wide Input Ac/Dc Switching Power Supply — Buy in wholesale FOB from Supplier in China

The TPC/GKF-320-XS series from Guangzhou Top Power Electronics Technology Co., Ltd. delivers a rated output power of 300 to 312 watts across a universal AC input range of 90 to 264 VAC. The series offers two regulated output options, 12 VDC and 24 VDC, with preset voltage tolerances held to within 0.10 V at 25 degrees Celsius. Efficiency reaches 84.5 percent at 12 V and 87 percent at 24 V under rated load conditions, with built-in active power factor correction maintaining PF greater than 0.95. A built-in cooling fan with speed control and altitude capability up to 5000 metres suit the unit for demanding installation environments without requiring an external heat sink.

The power supply employs a compact, ultra-small form factor that relies on internal thermal management rather than external heat sinking. Protection circuitry includes short circuit, overload, and overpower shutdown modes. The design is RoHS compliant and withstands 300 VAC surge inputs for five seconds, indicating compliance with industrial immunity standards typical of telecom and embedded equipment. Construction prioritises long service life and voltage stability over extended operating periods.

Target applications span telecommunications infrastructure, industrial process control, instrumentation, data acquisition systems, signal control arrays, new energy installations, security systems, DC motor drives, and CNC machinery. Buyers sourcing this unit should confirm with Guangzhou Top Power Electronics Technology Co., Ltd. the exact part number required, either TPC/GKF-320-12S or TPC/GKF-320-24S, since current ratings and output voltage differ substantially. Operating temperature range is -20 to 65 degrees Celsius, though derating curves for temperatures above 50 degrees Celsius should be requested from the supplier.

Guangzhou Top Power Electronics Technology Co., Ltd. maintains its registered address at Building No. 3, Rui Fa Road No. 15, Guangzhou Science Town, Huangpu District, Guangzhou 510530, Guangdong Province, China. The supplier holds an imported tier designation on the platform with a harbor trust classification. Both response rate and average response hours currently read zero, which indicates the supplier has not yet established a track record of inbound enquiry responsiveness through this channel. No factory audit details, employee counts, revenue figures, or client references are stated in the available profile.

The listing presents the TPC/GKF-320-XS series as the core product line, with emphasis on precision voltage regulation, built-in active PFC, and protection features for telecommunications and industrial control markets. Buyers should note that the profile does not list ISO certifications, UL file numbers, or CE declaration documentation, so compliance evidence should be requested directly. The supplier's location in Guangzhou Science Town places it within a major electronics manufacturing cluster, though this geographical observation does not imply any particular production scale or capacity.
