Top for 25 years

You can accept 25 years of success. Or celebrate it.

SITOP has been the heart of automation for 25 years, reliably supplying the right DC voltage to industries around the world. Our extensive portfolio of power supplies and add-on modules offers proven quality and reliability, maximum performance and maximum efficiency. And more besides: continuous development and constant innovation have already made SITOP the industrial power supply for Industrie 4.0.

There’s a good reason for success. Three, in fact.


Jörg Freitag

General Manager, Siemens Power Supplies SITOP

“For 25 years now, the SITOP product family has defined the market for industrial power supplies. The success story began in 1993, with the introduction of the ‘SITOP power basic line.’ It offered many benefits compared with the unregulated power supplies that dominated the market at the time, being smaller, lighter, and with a higher efficiency rating, all for the same price. Ever since, we have continued to define this market with innovative products and solutions. With our most recent innovations for system integration and open communication, we have made SITOP the perfect source of data for Industrie 4.0.


As our customer and partner, you have played a major part in this success story. A big thank you for being so committed to SITOP!”

“SITOP provides us with a broad range of products for all fields of application, and all current and voltage ranges. That makes performing all our tasks both technically efficient and cost-effective. We use Siemens components because we can simply install them and then forget about them.”

Rainer Sachert

Operating engineer Max-Planck-Institut for radio astronomy, Bad Münstereifel-Effelsberg, Germany

“The power supply is the Achilles heel of plant operation. To prevent a short-term voltage drop from causing malfunctions or putting individual parts of the treatment plant out of action, we fitted a modular protection system for our 24 V power supply using Siemens SITOP power supply units.”
