The package contains the 6AG1331-1SH03-7AA0 with screw terminals for input (L, N, each 0.5…2.5 mm²) and output (+, –, each with two terminals for 0.5…2.5 mm²). Internal fuse is fitted; an external miniature circuit breaker (6 A char. B or 2 A char. C) is recommended for the feeder but not included. Snaps onto standard DIN rail EN 60715 35×7.5/15. No separate mounting bracket required. Rated output is 1.3 A at 24 VDC, 50/60 Hz input. Above +55 °C ambient, derate 2% per K up to +70 °C. The maximum short-term current is 2.4 A; the I²t limit is 0.8 A²s, so the unit can handle motor inrush or capacitor charging within that energy envelope. Output voltage is adjustable 22.2…26.4 V — useful for compensating voltage drop on long cable runs. Response to a load step (10→90% or 90→10%) is 1 ms typical. Input range covers 100…240 VAC, 47…63 Hz, with initial inrush limited to 85 V minimum startup voltage. Efficiency is 85 % typical. Galvanic isolation provides SELV output per EN 60950-1 and EN 50178, so it's suitable for supplying 24 VDC control circuits and sensors. ## Clearance and panel placement Physical envelope: 54 mm wide, 90 mm high, 55 mm deep. Required free space around the unit: 20 mm above, 20 mm below, 0 mm left/right. IP20 rated — install in a suitable enclosure. EMC: EN 55022 Class B for residential and light industrial; immunity per EN 61000-6-2.","metaTitle":"Siemens 6AG1331-1SH03-7AA0 Power Supply, 24VDC 1.3A","metaDescription":"Siemens 6AG1331-1SH03-7AA0 power supply, 100-240VAC input, 24VDC 1.3A rated output, adjustable 22.2-26.4V.
