DEE VAN Enterprise was established in 1971
With over 5 decades of power design experiences, our products undergo strict adherence to ISO standards from design to production, making us a renowned power supply manufacturer both domestically and internationally.

Throughout the half-century journey, DVE has been a leading provider of high-quality equipment for a wide range of consumer electronics, from personal computers and networking devices to medical equipment and mobile communication devices. In recent years, we have expanded our focus to include energy-saving and energy storage products in alignment with the global push towards sustainability.

Since our inception in the early 1970s, we have earned international recognition and certification for our products, complying with stringent standards in countries such as Switzerland, the UK, Northern Europe, and Germany. We have also obtained certifications from respected organizations like UL in the United States and CSA in Canada. In 1995, we achieved ISO international quality certification, solidifying our position as a global leader in power supplies, transformers, and related products.

Beyond our business endeavors, we are committed to environmental sustainability. We have invested significantly in research and development and have implemented eco-friendly practices within our facilities. For example, at our LongChuan operation, over 40% of the total area is dedicated to green spaces, not only reducing greenhouse gas emissions but also improving overall environmental quality.

As we navigate the evolving landscape of global environmental change and sustainable development, we remain steadfast in our half-century legacy and continue to forge ahead confidently towards where our products and practices make a positive impact on the world.
