SITOP Power Supplies:

Sitop Power represents the new generation technology worldwide. We have sold more than 100,000 SITOP power supplies round the globe and this is one of our greatest success stories. Continuous customer feedback also provides the basis for consistent and intensive further development. Thanks to all of this, a new generation has emerged with even more functionality and more compact. This new generation has been downsized more than ever before. In addition, it's designed for universal applications running in severe, industrial environments or in sensitive public networks, whether in Europe, Asia, America, or elsewhere in the world.
The innovative product family -extremely user friendly and market compliant
With SITOP power, the user can get exactly everything that he needs, even graduated performance ratings. The members of the innovative SITOP power family consist of 2A, 5A, 10A, and 20A power supplies for connection to 120/230 V AC. The other product family includes power supplies delivering 10A, 20A, 30A, and 40A output current for three-phase AC networks between 360VAC and 550VAC. Since all power supplies satisfy class. B noise interference suppression requirements, these may be used without any trouble in residential areas. Along with the additional advantage of price, we provide 5A and 10A power supplies for strictly industrial environment.
By closely matching SITOP power to the needs of the market, we are able to offer range of products to suit customer budget and requirements, in the global market place. This in turn, provides long-term access to new export markets. Thus, SITOP power offers opportunities which do pay off immediately as well as in the future. The advantages of stabilized power are mentioned below:
Power for the AS I bus
SITOP power is the first choice for special and stringent uses. In order to supply power to the AS-I Bus, these are two specially designed power supplies with an output voltage of 30 V: 2.4 A IP 65 with 24 V input and 7 A with a wide input voltage range.
The powerful source is supplying stabilized power everywhere. It is a well-known fact that what ever runs in stabilized supplies lasts longer and is safer. This is true for DC power supplies. The other advantages of SITOP power are described below.
Efficient and cost-effective
It is now possible to lower current operating costs without losses in power by using SITOP power. The high efficiency of up to 90% guarantees considerably less power consumption and at the same time, distinctly lowers operating temperatures. Thus, critical values are reduced to the smallest common denominator.
Fast and low-cost installation
In SITOP power profitability is practically already included. Thanks to the light weigh of the whole product range and the simple DIN rail mounting, fast and cost-effective installation is guaranteed.
A longer lifetime through a higher quality of life
It is true that whatever is handled with care also lasts longer. The constantly stable 24 V output voltage protects against over and under voltages in the extended allowable range of variations of the input voltage. This in turn leads to a significant increase in the lifetime and operating safety of connected loads. In addition, up to 10% of leakage power can be saved. Furthermore SITOP power supplies optimally control network failures, over voltage surging, or HF interference keeping the nominal current remains absolutely constant up to a temperature of 60° C.
Leading the world through innovation

All industrial fields worldwide are benefiting from the advantages of stabilized power supplies. Especially those using Sipower and Sitop Power receive the highest benefits. The advantages these power supplies offer are:
Two families to choose from, Sitop Power
These are switched mode power supplies made by Siemens AG, Germany, with excellent aesthetics for smarter look-up. The family includes an entire range from 24V/2A to 24V/40A power supplies (single phase, three phase). With an extremely high efficiency of around 90%, they reduce energy wastage drastically. They open way to the export market as they come with all major certifications including the prestigious CE mark. The CE mark enables these to be sold in the European market.
Sipower
When it comes to design, reliability, protection and cost-effectiveness, these indigenously developed and manufactured switched mode power supplies stand ahead of the best in the world. With a unique price by performance ratio, Sipower power supplies fit in perfectly for lower power application of single phase 24V/2A and 24V/5A. Sipower is highly suitable for the Indian power/mains conditions, owing to the various protection and safety functions and ability to withstand tough environmental conditions. The economy is ensured by saving upfront cost and running costs due to low price and high efficiency.
Efficient and cost-effective
The high efficiency of up to 90% of the power supplies guarantees considerably less power consumption and distinctly lowers the heat dissipation. This reducing the need of forced cooling. It further results in lower current operating costs without loss in power. The light and compact power supplies eliminate the need of huge panels which further brings down the panel costs.
Extend the lifetime of your equipment
The constant stable 24V output voltage protects modules against over voltage and under voltage in the extended allowable range of variations of the input voltage. This not only improves the operating safety but also ensures a longer lifetime of the modules.
Build in safety with built-in safety
It is owing to the integrated electronic short-circuit protection that has done away with the need of additional fuses in the 24V circuit. A substantial output buffering time ensures a minimum power for some time immediately after a mains power failure. This makes it highly suitable for use with programmable controllers. The power supplies are available in the technical specifications.
