This industrial automation module accepts wide-range AC\/DC inputs (120\/230 V) and provides mains buffering of 20 ms to ride through brief interruptions. With an optional backup battery (3.6 V \/ 2.2 Ah lithium AA), it ensures data retention during power loss. Part of the Siemens PS407 family, the 6ES7407-0KA02-0AA0 is designed for high reliability in demanding manufacturing environments.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput voltage:\u003c\/strong\u003e 120\/230 V AC\/DC (rated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput voltage:\u003c\/strong\u003e 5 V DC and 24 V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput current (5 V DC backplane bus):\u003c\/strong\u003e 10 A (no base load required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput current (24 V DC backplane bus):\u003c\/strong\u003e 1 A (idling-proof)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive power input (typ.):\u003c\/strong\u003e 95 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower loss (typ.):\u003c\/strong\u003e 20 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInrush current (max.):\u003c\/strong\u003e 63 A (full width at half maximum 1 ms)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLeakage current (max.):\u003c\/strong\u003e 5 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains buffering:\u003c\/strong\u003e 20 ms stored energy time\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional backup battery:\u003c\/strong\u003e 1x lithium AA, 3.6 V \/ 2.2 Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x H x D):\u003c\/strong\u003e 50 mm x 290 mm x 217 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e approx. 1 200 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmbient temperature (operation):\u003c\/strong\u003e 0 °C to 60 °C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDegree of protection:\u003c\/strong\u003e Equipment protection class I with protective conductor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards:\u003c\/strong\u003e FM approval (Ta: 0 °C to 70 °C T4), BIS, compliance with IEC 61000-3-2 and IEC 61000-3-3\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eReal-World Applications\u003c\/h2\u003e\u003cp\u003eThe Siemens 6ES7407-0KA02-0AA0 power supply is ideal for continuous process lines, such as chemical plants or automotive assembly, where voltage stability protects downstream S7-400 PLC modules. Its wide input range accommodates global power grids, reducing inventory complexity. The 20 ms buffering ensures ride-through for short dips, preventing costly production stops. In energy-sensitive applications, the optional battery backup maintains configuration data, supporting quick recovery after outages.\u003c\/p\u003e\u003ch2\u003eMaintenance and Reliability\u003c\/h2\u003e\u003cp\u003eTo maximize ROI, inspect the Siemens 6ES7407-0KA02-0AA0 annually for dust accumulation on the fanless heatsink and verify battery voltage if installed. Operating within 0 °C to 60 °C avoids thermal stress. The short-circuit protection and overvoltage category II isolation extend service life. With a typical power loss of 20 W, this unit contributes minimal heat to the cabinet, reducing cooling requirements. These features lower total cost of ownership compared to less efficient alternatives.\u003c\/p\u003e\u003ch2\u003eSelection Guide and Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing the Siemens 6ES7407-0KA02-0AA0, confirm your S7-400 rack has two free slots for this power supply module. Verify that your input voltage matches 120-230 V AC or DC. For applications requiring data backup, order the optional lithium AA battery separately (3.6 V \/ 2.2 Ah).
