Input flexibility covers 120 V AC, 230 V AC, 120 V DC, and 230 V DC — a single unit handles both AC and DC mains, which simplifies stocking for panels that ship to sites with different utility feeds. ## Temperature range and battery backup — the real-world envelope Without the external battery box, the standard operating range is 0 °C to +60 °C using internal lithium AA cells. With the SIPLUS battery box 6AG1971-0AA00-7AA0 and MONO D-cell batteries, the range widens to -25 °C to +70 °C, which is the key difference from the standard 6ES7407-0KR02-0AA0. The standard 6ES7407-0KR02-0AA0 is rated for 0 °C to +60 °C and does not carry the SIPLUS extended-temperature or conformal-coating designation. If your application sees sub-zero startups or sustained heat near 70 °C, the 6AG1407-0KR02-7AA0 is the correct choice. Backup battery support is optional but specified: internal 2x lithium AA (3.6 V / 2.3 Ah) for 0 °C to +60 °C, or the external box with 2x MONO D-cells for the full -25 °C to +70 °C range. ## Panel fit and electrical integration Equipment protection class I with protective conductor. Inrush current is 63 A peak (full width at half maximum 1 ms), leakage current max 3.5 mA. Overvoltage category II. Mains buffering per NAMUR recommendation is supported, with a stored-energy time of 20 ms on mains failure. Typical power loss is 20 W; active power input is 95 W typ.","metaTitle":"Siemens 6AG1407-0KR02-7AA0 SIPLUS S7-400 PS, 120/230 VAC","metaDescription":"Siemens 6AG1407-0KR02-7AA0 SIPLUS S7-400 power supply, 120/230 VAC/VDC input, 10 A backplane bus at 5 VDC, -25 to +70°C with external battery box.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Industrial PCs"],"specifications":{"Max.":"70 °C; using the external battery box SIPLUS 6AG1971-0AA00-7AA0 for buffer mode","Min.":"-25 °C; using the external battery box SIPLUS 6AG1971-0AA00-7AA0 for buffer mode","Depth":"217 mm","Width":"50 mm","title":"6AG1407-0KR02-7AA0","5 V DC":"Yes","Height":"290 mm","24 V DC":"Yes","120 V AC":"Yes","120 V DC":"Yes","230 V AC":"Yes","230 V DC":"Yes","description":"SIPLUS S7-400 PS 407 10 A based on 6ES7407-0KR02-0AA0 with conformal coating, -25…+70 °C, 10 A, wide range, 120/230 V UC; 5 V DC/10 A, for redundant use","Required Slots":"2","Weight, approx.":"1 200 g","lifecycle_stage":"current","Power loss, typ.":"20 W","Primary/Secondary":"Yes","Rated value 50 Hz":"Yes","Rated value 60 Hz":"Yes","Inrush current, max.":"63 A; Full width at half maximum 1 ms","Overvoltage category":"II","Leakage current, max.":"3.5 mA","Type of output voltage":"DC","Rated value at 120 V AC":"0.9 A","Rated value at 120 V DC":"1 A","Rated value at 230 V AC":"0.5 A","Rated value at 230 V DC":"0.5 A","Active power input, typ.":"95 W","Short-circuit protection":"Yes","Backup battery (optional)":"Yes; 0 °C to +60 °C: 2x lithium AA; 3.6 V/2.3 Ah // -25 °C to +70 °C and/or 100 % RH: 2x external battery box 6AG1971-0AA00-7AA0 and 2x MONO cell design D","Equipment protection class":"I, with protective conductor","Permissible Range, Lower Limit":"47 Hz","Permissible Range, Upper Limit":"63 Hz","Design of electrical connection":"3x 1.5 mm², solid or stranded wire with end sleeve, external diameter 3 mm to 9 mm","for backplane bus (5 V DC), max.":"10 A; no base load required","for backplane bus (24 V DC), max.":"1 A; idling-proof","Mains/voltage failure stored energy time":"20 ms","Installation altitude above sea level, max.":"2 000 m","Protection against fouling acc. to EN 60664-3":"Yes; Type 1 protection","Mains buffering according to NAMUR recommendation":"Yes","Ambient air temperature-barometric pressure-altitude":"Tmin ...
