What are the uninterruptible power supplies that output 24v

Uninterruptible power supplies (UPS) protect the 24 V supply voltage against unexpected power failures. In the BLOCK portfolio, capacitive UPS solutions provide 24 V DC power supply for up to several minutes. Equipped with ultracapacitors, these solutions are designed for long service life and operation in demanding temperature ranges.

Certain automation devices can work with a variety of voltages; however, most control system components like HMIs, PLCs, I/O modules, and relays have been designed to use a 24V DC power supply.

The choices can feel overwhelming, especially when every detail matters. One option that stands out for both versatility and power is the 24V power supply. This type of power supply isn't just any regular power source—it's a balanced solution offering efficiency, reliability, and power, all rolled into one compact unit.

There are two main types of 24V DC power supplies – linear and switch mode. Linear power supplies are older technology and less expensive, but they have a stable DC voltage output with little electrical noise.

PLCs, sensors and actuators are usually provided with 24 V DC from a switched-mode power supply. Modern power supply units such as SITOP offer a maximum degree of security for the supply. However, they are not invulnerable to longer power supply failures. Critical applications therefore require upgrading to an uninterruptible power supply.

This UPS module for 24 V DC with output currents that range from 5 to 40 A enables the user to create a custom solution which combines a power supply, a UPS module and energy storage. It operates on a nominal input voltage of 24V DC, supporting a range of 18V to 30V DC. Yes, it supports parallel connection with up to two modules for redundancy.
