The Siemens 6EP1334-1LB00 is a SITOP PSU100L single-phase power supply that converts a switch-selectable 120 V or 230 V AC input into a stabilized 24 V DC output at up to 10 A. It delivers 240 W of active power at 89% efficiency, mounts on a 70 x 125 x 120 mm DIN-rail housing, and carries an MTBF of 2,333,396 hours at 40°C.
The 10 A / 240 W rating sits at the top of the PSU100L 24 V line covered here, suited to cabinets with a heavier PLC-plus-I/O load than the lower-current variants can carry on one unit. Like the rest of the PSU100L line it supports parallel-switching two units for extra power headroom, and the output is field-adjustable between 22.8 V and 26.4 V via the on-device potentiometer — the same trimming procedure used across the PSU100L range regardless of current rating.
DIN-rail 24 V DC supply for cabinets with larger PLC/IO/HMI loads — multi-slot rack systems or larger machine control panels — running on 120/230 V single-phase AC mains where up to 240 W of continuous output is needed from one unit.
