The Siemens 6EP1336-1LB00 is a SITOP PSU100L stabilized power supply converting 100-240 V AC (85-264 V wide-range) input into a regulated 24 V DC / 20 A output. It reaches 92% efficiency, delivers a constant-current short-circuit characteristic at 24 A, and mounts on a standard 35 mm DIN rail in an IP20 enclosure measuring 110 x 125 x 125 mm.
The 20 A rated output with a 24 A constant-current short-circuit characteristic sizes this unit for panels needing more headroom than a 10 A SITOP module - two PSU100L units can be paralleled to raise available current further. Wide-range 85-264 V AC input, which also accepts 88-370 V DC, means the same part works across single-phase mains variations without a voltage-selector switch. The output voltage trim range of 22.8-26.4 V via the onboard potentiometer lets it compensate for voltage drop on long DC distribution runs to remote I/O.
Used as the 24 V DC bus supply for PLC racks, remote I/O, and sensor/actuator power in control panels where load current exceeds what a compact 24V/10A supply can deliver.
