Delta was established in 1971 to provide power supply and heat dissipation treatment programs for the world. Over the past 20 years, Delta's development in Chinese mainland has become increasingly deep-rooted, and its business operations cover development, production, sales and service. With innovative skills, continuous strengthening of engineering development equipment and sophisticated testing equipment, Delta continues to introduce efficient, energy-saving, and reliable products and treatment plans.
Delta has a deep history in the development and production of general-purpose inverter products. In response to the needs of domestic customers, Delta has developed two types of inverters. The first is a general standard product, which has a wide range of applications and can comprehensively improve the automation level of customer equipment. The other category is special products for occupations, which are developed for the special processes and needs of occupations.
