Siemens 6EP4348-7RB00-0AX0 SITOP RED1200 24/48V 80A Power Supply Redundancy Module

The Siemens 6EP4348-7RB00-0AX0 is a SITOP RED1200 redundancy module that decouples two parallel 12-48 V DC power supplies feeding a single 24 V-class output rated 80 A. It reaches 97.5% efficiency and keeps the load powered if either input supply fails, with each input path protected by internal decoupling, suited for machines where continuous operation must survive a single supply fault.

Selection Notes

RED1200 decouples two SITOP power supplies sharing one 24 V output rail, so either supply can fail or be serviced without an output interruption; pick this over simple diode-OR redundancy when 80 A total output and 97.5% efficiency matter more than the lower cost of a diode module. An input range down to 12 V DC also allows pairing with 24 V or 48 V-class supplies on the same rail.

Applications

Used downstream of two parallel SITOP supplies in process control, machine safety circuits, or continuous-production lines where a single power-supply failure must not interrupt the 24 V DC load.
