Siemens 6EP1433-0AA00 SITOP PSU300E 3AC 400-500V 24V/5A DIN Rail Power Supply

The Siemens 6EP1433-0AA00 is a SITOP PSU300E three-phase power supply that converts 400-500 V AC into a stabilized 24 V DC output rated 5 A (120 W). It mounts on a 42 mm-wide DIN rail, holds the output adjustable from 24 to 29 V via potentiometer, and bridges a 50 ms mains dropout at rated load, suited to 24 V loads fed directly from a 400 V three-phase distribution board.

Selection Notes

The 6EP1433-0AA00 draws directly from a 3-phase 400-500 V distribution board rather than the single-phase 100-230 V input used by the SITOP PSU100 series, which matters where the panel already has three-phase power and a single-phase tap would add wiring. Output is adjustable to 29 V (up to 120 W) via potentiometer, useful for compensating voltage drop on a long 24 V run or lifting the set point for downstream equipment specifying a slightly higher supply. No internal input fuse is fitted, so the recommended external protection, a 6 A characteristic B or C miniature circuit breaker or an equivalent motor-protective circuit breaker, must be installed in the feeder for the unit to be protected against an upstream fault.
