Product details

Siemens SITOP 6AG1332-0TA00-7AY0 is a regulated, galvanically isolated DC power supply. Output adjusts from 24 to 28 VDC, rated 3.5 A continuous with no derating up to 70 °C. Input accepts DC from 18 V up to 264 V — wide enough for common nominal voltages or a floating battery bank. Efficiency hits 85 %, so panel heat rise stays manageable.

The 32 mm width snaps onto a standard DIN rail (EN 60715 35×7.5/15). Clearance needed: 50 mm top and bottom for airflow; sides can be flush (0 mm left/right). Depth 100 mm. Output terminals are double screw per pole (+, -) accepting 0.5–2.5 mm²; input uses L, N, FE single terminals same wire range. The internal fuse is 15 A, 100 A breaking capacity, not user accessible. A 16 A MCB (B or C curve) in the feeder is recommended. Start-up voltage is 88 V (though the module begins operating as low as 18 V). Full-scale input is 264 VDC. Line frequency tolerance 47–63 Hz was checked for AC ripple cases.

EMC and signal quality

Emitted interference per EN 61000-6-3, immunity per EN 61000-6-2. That puts it in standard industrial environments — not medical or railway, but fine for most control panels. Output is controlled, isolated DC voltage, which means less noise coupling into downstream 24 V loads. The 0.5 s response delay and 20 ms maximum hold-up time define ride-through during input dips. MTBF at 40 °C is over 1.9 million hours — a long window before you budget a spare for the BOM.
