That 95 K window covers unheated enclosures, outdoor-adjacent cabinets, and process areas where the standard 0…60 °C part would drift outside its guaranteed operating range. ## Output rails and backplane loading The primary backplane bus delivers 10 A at 5 V DC, derated to 7 A above 60 °C — no base load required. Separate 24 V DC, 48 V DC, and 60 V DC input rails supply 4 A, 2 A, and 1.6 A respectively, each with short-circuit protection. The 5 V backplane current is the figure that governs how many S7-400 modules one supply can feed; the 24 V rail handles field-side loads like digital input modules or small relays. Typical power loss is 20 W, active power input 95 W. The inrush current peaks at 18 A for 20 ms — within the rating of a standard C-curve MCB on the primary side. ## Conformal coating and environmental qualification The conformal coating per IPC-CC-830A Class A protects against condensation, conductive dust, and corrosive gas exposure up to EN 60721-3-3 class 3C4 levels. The unit also carries ANSI/ISA-71.04 GX group A/B qualification (excluding trichlorethylene) and salt-spray / oil resistance at levels LC3 and LB3. This is the variant to specify when the cabinet shares a floor with chemical processing, wastewater, or coastal installations. Installation altitude reaches 5 000 m with derated temperature — above 2 000 m the max ambient drops 10 K per 1 500 m increment. Overvoltage category II, equipment protection class I with protective conductor.","metaTitle":"Siemens 6AG1405-0KA02-7AA0 SIPLUS S7-400 PS 405, 10A","metaDescription":"Siemens 6AG1405-0KA02-7AA0 SIPLUS S7-400 PS 405 power supply, 10A wide-range 24/48/60 VDC input, conformal coating, -25 to +70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Supplies"],"specifications":{"Max.":"70 °C; = Tmax","Min.":"-25 °C; = Tmin","Depth":"217 mm","Width":"50 mm","title":"6AG1405-0KA02-7AA0","5 V DC":"Yes","Height":"290 mm","24 V DC":"Yes","48 V DC":"Yes","60 V DC":"Yes","description":"SIPLUS S7-400 PS 405 10 A based on 6ES7405-0KA02-0AA0 with conformal coating, -25…+70 °C, power supply, wide range 10 A, 24/48/60 V DC; 5 V DC/10 A","Required Slots":"2","Weight, approx.":"1.2 kg","lifecycle_stage":"current","Power loss, typ.":"20 W","Primary/Secondary":"Yes","Inrush current, max.":"18 A; Full width at half maximum 20 ms","Overvoltage category":"II","Rated value at 24 V DC":"4 A","Rated value at 48 V DC":"2 A","Rated value at 60 V DC":"1.6 A","Type of output voltage":"DC","Active power input, typ.":"95 W","Short-circuit protection":"Yes","Backup battery (optional)":"Yes; 2x lithium AA; 3.6 V / 2.3 Ah","Equipment protection class":"I, with protective conductor","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; 7A @ > 60 °C, no base load necessary","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.":"5 000 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 ...
