Siemens SITOP UPS 1600/UPS 1100: High reliability DC uninterruptible power supply system for industrial automation

USB interface (-1AY0): Used to connect to a PC and run the free SITOP UPS Manager software provided by Siemens for configuration, monitoring, and data analysis.

Integrated web server: No additional software is required, remote access can be achieved through a web browser to view real-time data, alarm history, trend charts, and perform user management (V2.1 and above versions support HTTPS and write access). The web server is not activated by default when it leaves the factory (starting from V2.1).

Seamless integration into the industrial automation ecosystem

The design of SITOP UPS1600 fully embodies the concept of "fully integrated automation".

TIA Portal Integration: UPS1600 can appear directly in the hardware directory from TIA Portal V13 (in conjunction with HSP) or by installing GSD files (TIA Portal V12). Users can drag it into the network view, assign controllers, and easily configure battery modules just like configuring other PROFINET devices. All parameters, such as buffer time, switching threshold, charging parameters, and web server settings, can be centrally configured in the device properties and downloaded to the device.

SITOP UPS Manager software: This free software running on Windows XP/7 provides more powerful local monitoring and management capabilities. It supports connection via USB or Ethernet to achieve:

Comprehensive device parameter configuration and firmware updates.

Trigger custom applications based on events such as power failure, insufficient buffering time, and battery replacement (such as shutting down the computer, sending emails/SMS).

Intuitive trend chart display, showing the historical changes of parameters such as load current, input voltage, and remaining buffer time.

Master slave operation: Under Ethernet connection, a PC can be configured as the master station to manage other PCs acting as slave stations in the network and achieve coordinated shutdown of devices within the network.

OPC UA Server Function (since V4.71): Provides a non proprietary interface for standardized, cross platform data access, facilitating integration with higher-level MES or SCADA systems.

Integration with SIMATIC STEP 7 Classic: For users using STEP 7 V5.4 and above, UPS1600 can also be integrated into PROFINET IO systems for configuration, parameter allocation, and diagnosis by installing GSD files.

Key points of engineering design, installation, and maintenance

Safety and Regulations: The manual emphasizes at the beginning that the equipment must be operated by qualified personnel in accordance with relevant documents and safety regulations. Installation must comply with DIN/VDE or local regulations (such as EN 50272-2). The input 24V power supply must comply with the SELV standard (EN60950-1).

Installation and wiring:

UPS1600: The standard installation position is vertical, with the terminals facing downwards to ensure heat dissipation. Maintain a minimum distance of 50mm between the top and bottom. The power terminals (IN, OUT, BAT) support different wire diameters (such as the 10/20A model supporting 0.2-6mm ²), and require the use of cables with a temperature resistance of at least 90 ℃ (in compliance with UL508).

UPS 110: Supports wall mounted or rail mounted installation (some models). Installed in the coolest position of the control cabinet (such as the lower part). When connecting battery modules, it is necessary to ensure that the power line (X1) and communication line (X2) are correctly connected, and that the parallel connected battery modules have the same model and status as much as possible.

Maintenance: The battery is designed to be maintenance free, but has a certain lifespan (approximately 4 years at 20 ° C). SITOP UPS 1100 provides a convenient battery replacement process: open the cover, press and hold the replacement button for more than 2 seconds (LED flashing), remove the fuse, replace the battery with the same model, press and hold the button again to confirm, and then reinstall the fuse. The system will automatically reset the relevant running timers and counts.

Technical data and environmental adaptability

The system demonstrates a robust industrial grade design:

High efficiency: The full load efficiency can reach 97.5% -98.5%, with low power loss.

High MTBF: Under 40 ° C, rated load, and 24-hour operating conditions, the average time between failures exceeds 320000 hours.

Wide environmental range: The working temperature of UPS1600 is -25 ° C~+70 ° C (natural convection, derating is required at 70 ° C), and the storage temperature is -40 ° C~+85 ° C. The working temperature of the UPS 110 battery module is usually 0 ° C~+40 ° C (some new versions support -15 ° C~+50 ° C).

Altitude impact: When operating above 2000 meters, for every 1000 meters increase, the output current needs to be reduced by 7.5%, or the ambient temperature needs to be reduced by 5K.

Complete certification: equipped with multiple international certifications such as CE, cULus, ATEX/IECEx explosion-proof (II 3G Ex nA nC IIC T4 Gc), CB, GL classification society, etc.

Strong electromagnetic compatibility: Complies with EN 61000-6-2 (industrial environment immunity) and EN 61000-6-3 (residential emission) standards, and has good ESD, EFT, and Surge immunity capabilities.
