Preliminary Technical Data

VDE 0884 INSULATION CHARACTERISTICS

This isolator is suitable for basic electrical isolation only within the safety limit data. Maintenance of the safety data must be ensured by

means of protective circuits.

An asterisk (*) on packages denotes VDE 0884 approval for 560 V peak working voltage.
