Description
The AC 800F modules are supplied with 5 V DC / 5 A and
3.3 V DC / 5 A auxiliary power by the SA 801F or 5 V DC / 5.5 A
and 3.3 V DC / 6.5 A by the SA 811F power supply. The power
supply has open-circuit, overload, and sustained short-circuit
protection. The electronically controlled output voltage provides
high stability and low residual ripple.
In case of power loss ≥5 ms, the power supply module gener
ates a power-fail signal. The CPU module uses this signal
to shut down operations and enter a safe state. This is re
quired for a controlled restart of the system and the user appli
cation when power is restored. The output voltage remains
within its tolerance limits for at least another 15 ms. Altogether a
maintains a voltage drop of 20 ms will be managed.
