Server Storage Networking (SNT)

 

AC/DC Power Supply (6000W)
with 98 % efficiency

Delta’s worldwide R&D team has accumulated decades of experience and knowledge in developing highly sophisticated customized power supplies for well-known companies in the IT domain, networking and telecommunications industry. We have applied our knowledge into developing new products beyond traditional power supplies which enabled us to become a system solution provider.

In 2016 more than 20 products have been launched and transferred from design to mass production. Efficiency continued to be the key driver for our customers, especially for the Internet industry. In addition to efficiency, higher power density is a key requirement especially because of the open compute server market. We have met these dynamic market requirements by incorporating a new circuit topology using high integrated magnetic component design, the latest semiconductor technology and a modular design approach, to achieve the highest possible power density and efficiency. Delta deployed a new platform design, rated to 3kW power with power density of 60W/in³ and peak efficiency of 97% to several custom specific products. In addition, Delta team has developed the next generation technology to achieve efficiency > 98 % with same power density. Here the next step for a 6 kW AC/DC technology platform was developed as well and will be rolled out in the next year. These technology platforms have a high degree of standardization and allow flexible customization with minimum design effort. So one platform design is the basic for multiple custom specific product.

In addition to pure power supply design, R&D’s core achievement was the continuous extension of our product offering to additional products used in Datacenters, like complete severs shelfs with distribution panel and power distribution units. Our R&D team was able to meet and even surpass our customers’ expectations moving forward to solutions offering.

Power Solutions for Electric Vehicles (EV)
