Product Overview
The 6EP1961-3BA01 is a DIN-rail-mount buffer module in Siemens' SITOP PSE201U family. It provides a short hold-up time (buffer) on 24 V DC power rails to maintain system voltage during brief interruptions. Supporting up to 40 A of output current, it is used to bridge short power failures in automation control systems, such as PLC racks, distributed I/O, and safety power circuits.
Best Suited For
- Bridging short power interruptions in 24 V control systems
- Maintaining PLC and I/O operation during supply faults
- Integration into SITOP smart/modular power architectures
- DIN-rail mounting in control panels
- High-current 24 V buffer for critical loads
