The SIEMENS 6EP1961-3BA21 is a SITOP PSE202U redundancy module designed to manage 24 V DC power distribution and provide reliable redundancy for dual power supplies. It allows decoupling of two SITOP power sources, handling up to 40 A total with a maximum of 20 A per output, so connected loads continue to receive power if one supply fails. Use it to maintain continuous operation of control systems, reduce downtime during supply faults, and simplify power system layouts where dual-supply redundancy is required.
