PRODUCT DESCRIPTION
6ES7405-0DA02-0AA0 DC rack power supply
Siemens 6ES7405-0DA02-0AA0 is a PS 405 DC power supply for SIMATIC S7-400 automation racks. It converts the documented 24, 48 or 60 V DC supply into the backplane voltages required by compatible rack modules.
The single-slot supply delivers up to 4 A at 5 V and 0.5 A at 24 V. It provides 20 ms input-interruption bridging and accepts optional lithium backup batteries for supported rack backup functions. Primary-to-secondary isolation and the documented inrush and power-loss values guide DC distribution and enclosure design.
