  • Description

The Siemens 6EP4346-7RB00-0AX0 SITOP RED1200 is a redundancy module that decouples two SITOP power supplies, each up to 10 A, into a single 24/48 V DC output rated 20 A. It reaches 97.5% efficiency with only 0.1 W no-load loss, letting either input source fail without interrupting the downstream 24 V bus.

Selection Notes

A 20 A rated output paired with two inputs each capped at 10 A (per the module's two-supply decoupling spec) means this RED1200 unit is sized to redundantly back a load up to 20 A total — for a larger protected load, a higher-current SITOP power supply pair is needed upstream, not a different RED1200 variant. The output formula (Vin - approx. 0.6 V) indicates diode-based decoupling, so it needs no control power or configuration and drops directly into an existing 24 V DC bus between two supplies. The -40…+70 °C operating range and 97.5% efficiency keep self-heating low even in sealed enclosures.

Applications

Redundant 24 V power feeds for PLCs and safety-critical control loops, and dual-supply cabinet designs that need to eliminate a single point of failure.
