All-Si PSUs (6000W & 3000W variants)
employing cost effective standard Mosfets.

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 2017 we were able to get the award of the Power-Shelf for the new open19 community. The Shelf hosts 6 AC/DC PSUs with 3200W and 12V output, which output power is current limited and splitted into 50 separate outputs. Each of the outputs is capable to act like a 400W PSU with all features known from a AC/DC supply, like PMBus monitoring, turn on/off, hot-plug, current limit, short circuit protection, etc.. This system includes 50 PSUs with standard 1U height which are installed in a centralized Rack. The system has the advantages of a modular, distributed power architecture on the one hand and on the other hand the benefits of a high power centralized architecture. In parallel to this complex design we are developing products with > 98% peak efficiency delivering 3000W and 6000W output power having at the same time a power density of > 60 W/in³. These 54V PSUs still use traditional Si-Mosfet technology and the high efficiency is realized by special control & modulation techniques.

These “base” technology platforms have a high degree of standardization and it can be used very flexibly for our new “rapid customized Standard” PSUs, which program was also successfully.

In addition to only power supply design, R&D’s core achievement was the continuous extension of our product offering to additional products used in Datacenters, like complete sever 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.
