Selection Notes

The 6EP3446-7SB00-3AX0 is the 10 A, 400-500 V 3AC-input member of the PSU6200 48 V family, the three-phase counterpart to the 1AC 6EP3346-7SB00-3AX0 at the same current and power rating. Choose this 3AC model where the panel already has a three-phase feed and the 1AC model's single-phase input would mean an extra transformer or tap; choose the 1AC model instead where only single-phase power is present. Within the 3AC PSU6200 line, step down to the 5 A variant for smaller 48 V loads under 240 W, or use the DIP-switch-selectable parallel mode with a second unit to extend the 480 W (576 W derated) ceiling for a larger 48 V DC bus. The redundancy module accessory applies here the same way it does across the PSU6200 family.
