Add-on modules
Add-on modules for protecting the power supply
Mission-critical processes and plants generally require additional protective measures. The SITOP add-on modules individually protect production lines and processes against different types of hazards, from power supply unit failure and overloads in the 24 V circuit to power failure on the input side or high inrush currents.
Add-on modules
Your power supply portfolio for every application
The comprehensive SITOP power supply portfolio offers controlled 24 V DC power supplies for a wide range of applications and requirements, while SITOP DC UPS and add-on modules extend power supply protection to the DC side in the event of power failures.
SITOP power supplies bring production to life
Regardless of the industry or the requirement, efficient and reliable power supply is the basic requirement for operating any plant. There are good reasons for using the extensively proven SITOP switched-mode devices, DC UPSs, and add-on modules.

Highlights of the SITOP power supply portfolio
The SITOP family is expanding with the new selectivity modules SITOP SEL1200 and SEL1400. But what’s the difference between the two new modules? Simply watch and find out for yourself what distinguishes a switching tripping characteristic from a limiting one.
In dialog with your power supply: The SITOP PSU8600 power supply system can be fully integrated in an automation system – in Totally Integrated Automation (TIA) via PROFINET or in OPC UA via Industrial Ethernet with open communication. The operating data is recorded and can provide diagnostic and maintenance information.
The heart of automation: SITOP power supplies are known worldwide for their extreme reliability and ability to handle critical network conditions. The portfolio contains controlled 24-V DC power supplies for a wide range of applications, while DC UPS and add-on modules extend power supply protection to the DC side in the event of power failures.
