The Siemens 6ES7307-1KA02-0AA0 is a PS 307 power supply for the S7-300 PLC system. It provides a rated output of 10 A across a 0 to 10 A range, accepting dual AC input ranges of 85 to 132 V and 170 to 264 V at 50/60 Hz (47 to 63 Hz). The 10 A rating means it can power a fully loaded S7-300 rack plus expansion modules without exceeding the supply's headroom — a common spec to check when adding analog or high-current digital output modules.
Mounts directly onto the S7 rail (the standard DIN-rail profile for S7-300). Output uses L+, M with four screw terminals each for the same wire range — handy for daisy-chaining 24 VDC to multiple modules without a separate distribution block. IP20 protection means it's for enclosed cabinets only, no washdown exposure.
Approvals and hazardous locations
Carries a full slate of hazardous-location approvals: ATEX II 3G Ex nA nC IIC T3 Gc, IECEx Ex nA nC IIC T3 Gc, and FM Class I, Div. 2, Groups A, B, C, D, T4. Also UL 508 and CSA C22.2 No. 142 listed (cULus, File E143289). This means it's accepted in Zone 2 / Division 2 environments across Europe, North America, and EAC jurisdictions — a key check for chemical, oil/gas, or pharmaceutical lines where standard industrial supplies won't pass inspection.
