DIN EN 60747-5-2 (VDE 0884 PART 2) INSULATION CHARACTERISTICS
This isolator is suitable for basic isolation only within the safety limit data. Maintenance of the safety data is ensured by protective circuits.
The * marking on the package denotes DIN EN 60747-5-2 approval for a 560 V peak working voltage.
