6EP1961-3BA21 SIEMENS

The SITOP PSE202U redundancy module (6EP1961-3BA21) from Siemens enhances power supply reliability by enabling redundant operation. Designed for a 24 V DC input and output, it supports a maximum current of 40 A. This module is specifically tailored to decouple two SITOP power supplies, each with a maximum output current of 20 A. By connecting two power supplies in parallel through the PSE202U, the system ensures continuous operation even if one power supply fails. The module automatically switches to the functioning power supply, preventing downtime and maintaining critical processes. Its robust design and seamless switchover capability make it ideal for applications demanding high availability. The SITOP PSE202U offers a cost-effective solution for creating a redundant power supply system, minimizing the risk of interruptions and maximizing system uptime. This redundancy module is easy to integrate into existing systems, providing a reliable and efficient way to enhance power supply resilience. It is suitable for various industrial applications where uninterrupted power is essential.
