A reliable, uninterruptible power supply is essential for maximum system availability. That’s why Siemens provides a full range of perfectly coordinated DC UPS modules with our SITOP power supply units. DC UPS devices provide secure and cost-effective protection should primary power fluctuate or fail, thus ensuring uninterrupted system operation.

Every power failure can bring a plant to a standstill and cost a lot of time and money. The SITOP DC UPS offers perfect protection against unexpected outages and ensures uninterrupted plant operation.
The buffer module reliably provides 24 V backup for up to 10 seconds for the SITOP smart and SITOP modular power supplies and even up to minutes through the maintenance-free DC UPS with capacitor technology. The DC UPS modules with batteries, which can communicate via Ethernet/PROFINET and are fully integrated in TIA (SITOP UPS1600), can reliably provide 24 V up to scale of hours.
The SITOP DC UPS systems differ in their storage capacity, their performance and in their functionality, for example, their ability to be integrated into the automation system requiring backup. The selection matrix is designed to give you some guidance for selecting the right 24 V backup for your application.
The SITOP Selection Tool supports you in selecting the right DC UPS configuration.

The OPC UA certification ensures the abidance of the following key aspects:
- Compliance to the OPC Specifications- Interoperability with other vendors’ products- Robustness and recovery from error conditions - Efficiency of CPU, RAM, and bandwidth etc.- Usability ensures a good user-experience
At +40 °C, the 5 Ah battery module LiFePo for the SITOP UPS1600 based on lithium iron phosphate only needs to be replaced after nine years, as compared to after one year for lead batteries.
The standardized interface is now integrated in the UPS Manager of the uninterruptible power supply UPS1600 and allows flexible integration into a wide range of systems.
Different 24 V supply concepts, such as redundant power supply or buffering in case of power failure, can be easily integrated into the process control system with the help of software blocks and faceplates. This means that PCS 7 users automatically receive information about operating status conditions, maintenance requirements or disturbances, e.g. power failure.
