从China供应商批发进口10w 4kv Isolation Wide Input Ac/Dc Converters — FOB条款

Guangzhou Top Power Electronics Technology Co., Ltd. supplies these 10W 4KV isolation wide input AC/DC converters from its facility in Guangzhou's Huangpu District. The unit delivers 10 watts of rated output power with a universal input voltage range that accepts both AC and DC sources, and a fixed switching frequency for stable conversion. The 4,000-volt isolation barrier protects downstream circuits and personnel, while built-in overheat protection extends component life under sustained load.

Converters in this class typically use a switching topology with an internal MOSFET and transformer to step down high-voltage input to a regulated low-voltage DC rail. Typical isolation test voltage for industrial-grade modules falls between 3,000 and 5,000 volts, placing this unit at the upper end of the common range. Industry-standard packages for 10W open-frame or encapsulated converters include pin-compatible SIP, DIP, and chassis-mount formats, and common output voltages span 3.3V, 5V, 12V, 15V, and 24V DC. Buyers should confirm the exact output voltage, package style, and operating temperature range with the supplier, as these details are not listed in the current data.

These converters are used in industrial automation controllers, telecom base stations, medical monitoring devices, and security systems where a compact, isolated power stage is needed. OEMs, system integrators, and contract electronics manufacturers sourcing from China typically request datasheets, RoHS or REACH declarations, and sample units before placing bulk orders. The supplier's listing references CE and ISO certifications, but buyers should verify current certificate numbers and validity directly with Guangzhou Top Power before committing to large-volume purchases.

Guangzhou Top Power Electronics Technology Co., Ltd. is based at Building No. 3, Rui Fa Road No. 15, Guangzhou Science Town, Huangpu District, Guangzhou 510530, Guangdong, China. The supplier is listed on the platform as an imported-tier seller with a harbour trust classification, though the current data shows a 0% response rate and no recorded average response time.

The listing positions the company as a provider of power electronics components, specifically AC/DC converters, for industrial and consumer applications. No details are provided on the company's founding year, workforce size, production capacity, export markets, or client portfolio. Buyers evaluating this supplier should request a company profile, factory audit report or video, and recent shipment references to assess manufacturing capability and reliability before placing orders.
