What it is and where it fits
The Siemens 6AG1332-4BA00-7AA0 SITOP power supply delivers a rated 3 A at 24 V DC output from a wide-ranging AC input (85–132 V and 170–264 V at 50/60 Hz). It mounts directly onto the S7-1500 rail, fitting into a 50 mm wide enclosure with dimensions 147 x 129 mm (H x D). Input connections are single screw terminals for L, N, and PE (0.5–2.5 mm²); the output side uses two spring-loaded terminals per pole (L+, M) for fast wiring—no tool needed for the power distribution.
Key ratings and what they mean
The controlled, isolated DC output carries a 1.3 A²·s I²t maximum and a 1.5 s response delay—the latter governs inrush behaviour when powering capacitive loads or driving downstream DC buses. EMC performance meets EN 55022 Class B for conducted and radiated emission and EN 61000-6-2 for industrial immunity—no external filtering needed in most standard control environments. The CE marking confirms compliance with the applicable directives.
