The 6ES7307-1BA00-0AA0: Output is 24 V DC at 2 A; that is the current budget for all modules fed from this supply rail on the S7-300 backplane. Mains buffering holds up the output for at least 20 ms at rated load with input at 93 V or 187 V — enough to ride through a half-cycle dropout. Overvoltage protection on the output shuts down the supply when voltage exceeds 28.8 V, then automatically restarts when the condition clears. No manual reset is needed, which simplifies remote panel recovery. Input is 1‑phase AC, rated 120 V nominal, accepts 85–132 V. Mains buffering is 20 ms at rated load with input at 93 V or 187 V.
