ABB SD 802F 3BDH000012R1 Power Supply Module

ABB SD 802F 3BDH000012R1 Power Supply Module      

Functional Description

The AC 800F modules are supplied with 5 V DC / 5 A and 3.3 V DC / 5 A auxiliary power by the SD 802F

power supply module. 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 an input voltage drop of 20 ms will be managed.

Features

· Redundant input voltage 24 V DC, provides operation in accordance with NAMUR
