Delta has a history of over 70 years in power management. The roots of Delta’s telecom power supplies are in the 1930s, when Hassler started collaborating with the Swiss PTT. In Finland, Valtion Sähköpaja (State Electric Works) began producing direct current (DC) power systems already in the 1940s. A merger combined the Swiss and Finnish operations in the early 1990s.

From Taiwan to global
Delta Electronics was founded in Taiwan in 1971. Under its owner and President Bruce Cheng, Delta began producing television coils and intermediate frequency transformers. Rapid growth led to annual sales of $100 million in the 1980s. Delta expanded to the US, Europe, Thailand and Japan, reaching third position in the US power supply market by the end of the decade. By 1994, Delta’s annual revenues exceeded $500 million. Two years later Delta crossed the $1 billion mark, and by 2000 its revenues exceeded $2.5 billion.

In 2003, Europe and Asia joined forces in the telecom power systems business in an acquisition. Today, over 4500 people work for UPS, telecom power and photovoltaic solutions and Delta has operations in more than 70 countries in this area.

Currently the power supply solutions of Delta cover a broad range of InD and OutD systems and HelpD services. The products are manufactured in all main markets in Asia, Europe and the Americas.

Delta has a similarly strong history in the uninterruptible power supply (UPS) business. The company began designing and manufacturing UPS solutions 15 years ago and has delivered its solutions around the world. Delta’s global service teams and partner networks ensure customer satisfaction by providing value-added support, service, spare parts and enhancements to safeguard customer investments and to ensure the efficient use of equipment.
