ABB Power Supply SA 801F / SA 811F

Features

Input voltage 115 – 230 VAC (self adjusting), output is elec

trically isolated

Power supply outputs provide:

SA 801 F: 5 V DC / 5 A and 3.3 V DC / 5 A

SA 811 F: 5 V DC / 5.5 A and 3.3 V DC / 6.5 A

Enhanced power-fail prediction and shutdown procedures

LED indication for power supply status and operating

status of the AC 800F

Short circuit proof, current limited

20 ms backup energy for use in the event of primary power

failure, according to NAMUR

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. This signal is used by the CPU module

to shut down operations and enter to 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

mains voltage drop of 20 ms will be managed.
