Product description
Siemens 6ES7407-0KA02-0AA0 is designed as the PS 407 10 A power supply for the backplane bus of a SIMATIC-S7-400 station. The input side covers 85 to 264 V AC and 88 to 300 V DC; the rated values are 120 V and 230 V for both alternating and direct voltage. With an AC supply, the permissible frequency range is 47 to 63 Hz. The secondary side provides 5 V DC at a maximum of 10 A and 24 V DC at a maximum of 1 A. No base load is required for the 5-V output, and the 24-V output is idle-proof. Stored energy bridges a line or voltage failure for 20 ms. Typical active power input is 95 W and typical power loss is 20 W. The module occupies two slots and has electrical isolation between the primary and secondary sides. Its design includes protection class I with a protective conductor and overvoltage category II. An optional lithium AA cell rated at 3.6 V and 2.2 Ah is specified as the backup battery. The permissible operating ambient temperature is 0 to 60 °C. The module measures 50 × 290 × 217 mm and weighs approximately 1,200 g. The 10-A output, wide-range input and full order number distinguish this PS-407 version within the S7-400 system.
