product overview
SITOP - Reliable 24V Power Supply
The efficient operation of a machine or factory requires a reliable and stable power supply. The high-quality and reliable SITOP power supply ensures a high level of DC power supply in the industrial engineering field and building systems. They not only provide a stable 24V power supply, but also other output voltage power supplies. Even under large input voltage variations, the output voltage can still maintain high accuracy stably. This allows the switching power supply to be used in numerous sensitive electronic systems - providing up to 40 A of current to the load. The naturally ventilated power supply has the characteristics of compact structure, sturdy design, high efficiency, and high overload capacity. The wide range of input voltages and international certification have enabled it to be widely used in various power grids around the world.
Complete SITOP power supply range
In addition to the power supply, the complete product line offers unique module options - from preventing mutual interference between the primary and secondary sides to providing full-featured protection.
Modular
High performance power supply for high demand solutions:
SITOP modular
The initiator and industry leader of modular power supply, Siemens' highly reliable 24V modular power supply excellently meets the usage requirements under extremely harsh conditions worldwide. This power supply product has a metal casing that can be securely installed on standard rails and can also be easily expanded with SITOP DC UPS modules and other expansion modules. This modular design not only brings unparalleled benefits to customers in terms of flexibility and ease of operation, but also in terms of cost-effectiveness.
Even without expansion modules, the SITOP power supply basic unit still has a wide range of functions. A wide range of voltage inputs can enable it to be applied in most parts of the world, even in different power supply networks, while also compensating for large voltage fluctuations to ensure stable output voltage. At the same time, a brief interruption in the power grid can still maintain a certain amount of DC power output. The single-phase SITOP power supply with output currents of 5 A and 10 A has a wide range of voltage inputs, making it suitable for two-phase or three-phase power grids.
The new SITOP power supply has impressively proven that even high-capacity power supplies with output currents of 20 A and 40 A do not require a lot of space. Its width is only 70 mm and 150 mm, which is relatively compact compared to similar products from other manufacturers with the same capacity and performance.
No matter how compact the design is, SITOP modular power supplies still have strong performance and can provide a high degree of safety. They can not only provide up to 3 times the rated current in a short period of time, but also have an overload capacity of 1.5 times the rated current for 5 seconds. Therefore, there is no problem with using it on loads with high starting currents. After overload, you can choose to start automatically or turn off the power.

extension module
Provide reliable protection against various power hazards:
SITOP extension module
The power unit cannot guarantee that it will not malfunction. Power outages, sudden changes in main voltage, or a load error can all lead to factory shutdowns, resulting in high costs. The expansion module provides protection against interference from the primary and secondary edges, up to full range protection.
Signal module: It combines signal control and remote on/off in an optimal way with SITOP basic models (components without complete signal control) to serve automation processes.
For a wide range of applications, redundant modules can decouple SITOP power supplies of the same type
The buffer module utilizes capacitors as energy reserves to provide 3 seconds of power on during power outages.
The SITOP diagnostic module and the new SITOP PSE200U selective module provide selective protection for individual overload and short-circuit paths of 24V. With this protection and fast fault location method, downtime is reduced to a lower limit. The new features of the selective module include fine adjustment of current range (from 0.5 A), remote reset, and individual channel button reset.
DC UPS
A 24V power supply that can be trusted even in the event of a power outage: uninterruptible power supply
Our power supply can ensure stable output even with millisecond level voltage fluctuations. Large voltage fluctuations, even power outages, undoubtedly require special measures: the buffer module (see SITOP expansion module) can ensure better protection for up to 3 seconds in the event of a brief power failure. Longer power outages up to the minute level can be bridged using the newer capacitor technology, maintenance free SITOP UPS500. A DC UPS module with a battery module can operate safely for several hours. These two DC UPS systems can be easily integrated into PC based automation solutions using free software tools.
The new SITOP UPS500 is completely maintenance free as it is stored in a large capacity energy double-layer capacitor, which has a long service life even at high temperatures and does not require replacement. Because there are no gas emissions, the installation location does not require ventilation. The innovative DC 24V UPS buffer range reaches the minute level, enabling backup data and safe shutdown of computer applications (such as using SIMATIC PC). The SITOP UPS 500S is designed specifically for installation on standard mounting rails and can be modularly expanded to extend backup times. The UPS500P with a protection level of IP65 is suitable for decentralized use. The SITOP DC UPS module using up to 12 Ah lead gel batteries can run continuously for several hours. Its effectiveness, battery power supply line, aging status, and charging status are monitored for a long time. A comprehensive battery management system ensures optimal charging of battery modules and a longer lifespan.
