DC-DC Converter Manufacturer

Shenzhen Wengao Electronic Co., Ltd. is a manufacturer based in Shenzhen, China, that designs and manufactures DC-DC converters and DC-DC battery chargers. The company was established in 2015, and its product range covers the conversion jobs that sit between a power source and the equipment it runs: stepping a voltage down, stepping it up, holding it steady across a wide input range, keeping input and output electrically separate, and charging a battery from a DC source while a vehicle or a vessel is running.

A DC-DC converter answers a practical question that comes up in almost every piece of DC-powered equipment: the available voltage is not the voltage the load needs. A 48 volt battery bank must feed 12 volt equipment. A 12 volt vehicle system must charge a 24 volt auxiliary battery. A telecom cabinet must deliver clean, isolated power to sensitive boards. Each of those jobs has its own converter shape, and this site is organised around those shapes rather than around a single generic product.

The catalogue is built on six lines. Isolated DC-DC converters keep the input and output circuits electrically separate, which suits telecom equipment, industrial control and other applications where noise or fault isolation matters. Buck DC-DC converters step voltage down, for example from 72 volts to 12 volts in a golf cart or an electric vehicle. Boost DC-DC converters step voltage up, for example from 12 volts to 48 volts. Buck-boost DC-DC converters cover both directions across a wide input range. DC-DC battery chargers charge lithium and lead-acid batteries from a DC source, including bidirectional models that move energy in both directions. Marine battery chargers are the onboard line for boats and vessels.

Only two product lines on this site carry full published specification sheets, and each of them has its own detail page. The first is the WGI10 isolated converter series, with an input range of 36 to 90 volts, a 12 volt output, a 10 amp output current, 120 watts of output power, and a 110 by 70 by 23 millimetre footprint. The second is the WG-BC1500M bidirectional battery charger series, which is waterproof, moves energy in both directions, communicates over RS485, and serves 12 volt, 24 volt, 36 volt and 48 volt lithium and AGM batteries. Every other product on this site is presented at category, application or selection level, with its voltage conversion or battery type stated and no invented performance figures.

Buyers often arrive with a system rather than a part number. A golf cart builder needs a reliable step down from a high-voltage pack to 12 volt accessories. A boat owner needs an onboard charger that works while the engine runs. An RV builder needs a dual battery setup that charges a house battery from the starter system. A telecom installer needs isolated power that keeps noise out of the cabinet. The application and selection pages on this site are written for those situations, and they point back to the category pages whose products match the job.

The company describes a catalogue of more than 500 models and a workforce of more than 100 people, and it describes exports to more than 130 countries, including the USA, Japan, Europe, Australia, Canada and Korea. Those are the company's own descriptions, and they are presented here as such. No individual customer is named anywhere on this site, and no export figure is broken down by customer or by country, because no such breakdown has been published.

If you are sourcing converters or chargers for a project, start with the category that matches your conversion, check the detail pages for the two lines with full specifications, and then send an inquiry through the contact form. State the input and output voltages, the battery type where relevant, and the application, and confirm quantity, price and delivery time during the inquiry, since those commercial terms are confirmed per inquiry rather than published here.
