DIN V VDE V 0884-10 (VDE V 0884-10) INSULATION CHARACTERISTICS
Note that the * marking on the package denotes DIN V VDE V 0884-10 approval for a 848 V peak working voltage. This isolator is
suitable for reinforced isolation only within the safety limit data. Maintenance of the safety data is ensured by protective circuits.
