AS-i power supplies monitor earth leakage

SAFE System operation is assured with these AS-interface power supplies from Phoenix Contact, thanks to an integrated earth leakage monitor system.

If two earth connections occur in an AS-i network, this can result in undesirable start-up and run-through of a machine. These power supplies recognise the first earth fault condition, and enable machines and systems to be shut down under controlled conditions.

The power supplies have a wide range of inputs from 100 to 240V AC and 130 to 370V DC.
