Siemens 6EP3336-7SB00-3AX0 SITOP PSU6200 24V DC/20A Power Supply 120-240V AC Input

The Siemens SITOP PSU6200 (6EP3336-7SB00-3AX0) is a stabilized 24V DC power supply rated 20A/480W, accepting a wide-range 120-240V AC or 110-240V DC input with automatic voltage selection. It includes a diagnostic interface output contact, buffers mains dips for at least 25ms, and reaches 95.5% efficiency in a DIN-rail-mount enclosure with push-in terminal connections.

Selection Notes

At 20A/480W, this PSU6200 variant sits above the smaller 5A SITOP PSU8200-class units; pick it when the connected load exceeds what a single lower-current unit supplies, or use the DIP-switch-selectable parallel mode with a second unit for N+1 redundancy or higher combined current. The electronic diagnostic contact (30V DC/0.1A) gives a wired DC-OK signal usable directly by a PLC digital input, unlike LED-only status indication.

Applications

Used for higher-current 24V DC distribution in machine-building and process panels needing wide-range AC/DC input flexibility, SEMI F47 voltage-sag immunity, and marine or offshore power distribution given its shipbuilding, ABS, and DNV approvals.
