Both limits assume the optional external battery box 6AG1971-0AA00-7AA0 is used in buffer mode — without it, the battery-backed memory hold-up range is narrower. ## Input flexibility and backplane loading It accepts 24 V DC, 48 V DC, or 60 V DC input, with rated currents of 4 A, 2 A, and 1.6 A respectively — so the input current drops as the bus voltage rises, but the output stays at 5 V DC. That 10 A backplane capacity is enough to power a fully loaded S7-400 rack with multiple CPUs and I/O modules; the 24 V DC rail handles any external field-side loads the rack's backplane supplies. ## Conformal coating and harsh-environment credentials The conformal coating (Class A per IPC-CC-830A) protects the PCB assembly from condensation, corrosive gases, and salt spray — it's rated for environmental conditions per ANSI/ISA-71.04 up to Level GX group A/B (excluding trichlorethylene) and Level LC3 (salt spray) and LB3 (oil). That makes this PS 405 a candidate for pulp and paper, chemical processing, offshore, or any location where standard S7-400 power supplies would fail from atmospheric attack.","metaTitle":"Siemens 6AG1405-0KR02-7AA0 SIPLUS PS 405 10A, -25…+70°C","metaDescription":"SIPLUS S7-400 PS 405 10 A power supply, conformal coated, 24/48/60 V DC input, 5 V DC/10 A backplane output, rated -25 to +70 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Industrial PCs"],"specifications":{"Max.":"70 °C; = Tmax; using the external battery box SIPLUS 6AG1971-0AA00-7AA0 for buffer mode","Min.":"-25 °C; = Tmin; using the external battery box SIPLUS 6AG1971-0AA00-7AA0 for buffer mode","Depth":"217 mm","Width":"50 mm","title":"6AG1405-0KR02-7AA0","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 6ES7405-0KR02-0AA0 with conformal coating, -25…+70 °C, 10 A, wide range, 24/48/60 V DC; 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","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; 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","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.":"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 ...
