The Siemens 6EP1333-3BA10 is a SITOP PSU200M stabilized power supply that converts 120-500 V single- or two-phase AC input into a regulated 24 V DC output rated at 5 A. Output voltage is adjustable from 24 to 28.8 V via potentiometer, with 88% efficiency and 25 ms buffering time to ride through short input dips.
The 5 A rated output suits compact DIN-rail automation panels that need a single-phase 24 V DC supply. The wide-range 85-550 V AC input covers both 120 V and 230 V mains via a selector switch, so no separate variant is needed for different supply voltages. Two units can be paralleled for N+1 redundant supply, and the 24-28.8 V adjustment range compensates for voltage drop over long field-cable runs.
Control-cabinet 24 V DC bus supply for PLC and I/O systems, machine-building panels, single-phase AC mains installations, and redundant power configurations using two paralleled units.
