Selection Notes

The 6EP3446-8SB10-0AY0 is the 36 V/13 A member of the compact PSU8200 family, sized for 36 V DC circuits found in some battery-backed or telecom-derived control systems rather than the more common 24 V or 48 V rails. It shares its 70 x 125 x 125 mm enclosure, input range, and mounting method with the 48 V/10 A PSU8200 sibling, so the two can be mixed on the same DIN rail layout without redesigning the cabinet. Choose the 48 V/10 A variant instead when the downstream load runs on a 48 V rail; this 36 V/13 A model's 468 W output is close to the other unit's 480 W, so the choice between them is driven by required output voltage rather than available power.
