Siemens 6EP3346-7SB00-3AX0 SITOP PSU6200 1AC 48V/10A DIN Rail Power Supply

The Siemens 6EP3346-7SB00-3AX0 is a SITOP PSU6200 single-phase power supply that accepts 120-240 V AC or 110-240 V DC input and delivers a stabilized, adjustable 48 V DC output rated at 10 A (480 W, 576 W up to 45°C), with galvanic isolation and a diagnostic interface reporting DC-OK status via an electronic contact.

Selection Notes

The 6EP3346-7SB00-3AX0 is the 10 A member of the PSU6200 1AC family, sized for control cabinets where a single-phase 120-240 V AC feed or 110-240 V DC is available rather than three-phase power. Its diagnostic contact reports DC-OK status directly through an electronic contact, useful when the downstream controller needs a hardware interlock rather than a fieldbus read. Pick the lower-current 5 A sibling for smaller 24-48 V DC loads under 240 W, and move to a higher-current PSU6200 variant when the connected load approaches the 480 W continuous rating (576 W is only available up to 45°C ambient, so derate above that point). The DIP-switch-selectable parallel operation lets two units share a larger 48 V DC bus for load sharing or basic redundancy, and the listed redundancy module accessory decouples the outputs for that purpose without modifying the base unit's wiring.
