Siemens 6EP1333-1LB00 SITOP PSU100L 120/230V AC 24V/5A DC Power Supply

The Siemens SITOP PSU100L 6EP1333-1LB00 is a single-phase stabilized power supply that converts a 120/230 V AC input, selectable by an on-device switch, into a controlled 24 V DC output rated at 5 A (120 W). It mounts on a DIN rail EN 60715, carries IP20 protection, and buffers the output for at least 20 ms during a mains dip.

Selection Notes

The dual-range 120/230 V input, switch-selected rather than auto-sensing, means the installer sets the correct range for the site mains before commissioning. At 5 A / 120 W rated output with 2 units allowed in parallel for redundancy or increased power, this PSU100L covers small to mid-size 24 V DC control loads; step up to a PSU100S or PSU300S output-current class if the connected load exceeds 5 A continuous. The 20 ms minimum buffering time at Vin = 93/187 V is the figure to check against the downstream PLC's ride-through requirement for short mains dips.

Applications

Powers 24 V DC control circuits, PLC I/O, and relay logic from a single-phase 120/230 V supply in control cabinets and machine panels where DIN-rail mounting and compact width matter.
