The Siemens 6AG1332-1SH52-7AA0 is a 24 VDC switched-mode power supply from the SITOP family, rated for 4 A continuous output from a universal AC/DC input. The output voltage adjusts from 22.2 to 26.4 V, covering the standard 24 V nominal and providing margin for line drops.
Input and output flex
Input accepts 47–63 Hz line voltage or DC 110–300 V. The feeder circuit should be protected with a 10 A B-curve or 6 A C-curve MCB. Output is galvanically isolated to SELV, with a typical response delay under 0.5 s and a load-step recovery of 1 ms (10–90%). I²t limit of 2.5 A²s helps coordinate upstream protection.
Snaps onto a 35×7.5/15 DIN rail per EN 60715. Dimensions are 90 mm wide, 90 mm high, 55 mm deep.
Thermal behaviour and derating
The internal fuse protects against short circuits, and IP20 enclosure keeps hands out. Efficiency is 89 % at rated load, keeping self-heating low inside the cabinet.
CE marked. Emission complies with EN 55022 Class B (residential/commercial limit) and immunity meets EN 61000-6-2 (industrial environment). No UL or CSA mark listed, so verify local code acceptability.
