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 generates a power-fail signal.

This signal is used by the CPU module to shut down operations and enter to a safe state.

This is required for a controlled restart of the system and the user application when power is restored. 

The output voltage remains within its tolerance limits for at least another 15 ms.

Altogether a mains voltage drop of 20 ms will be managed.
