Isolation


Galvanic isolation3-port isolation between input, output and power supply


Test voltage4 kV AC (input against output and power supply)
3 kV AC (output against power supply)


Working voltage1000 V AC/DC input against output and power supply with overvoltage category II
(basic isolation)ａnd pollution degree 2,
330 V AC/DC output against power supply with overvoltage category II and
pollution degree 2 according to EN 61010-1
For applications with high working voltages, you should ensure there is sufficient
spacing or isolation from neighboring devices and protection against electric shocks.


Protection against electriSafe isolation according to EN 61140 by reinforced insulation in accordance with
shockEN 61010-1.
Working voltages with overvoltage category II and pollution degree 2:
600 V AC/DC for input against output and power supply
with overvoltage category II and pollution degree 2:
300 V AC/DC for output against power supply.
For applications with high working voltages, you should ensure there is sufficient
spacing or isolation from neighboring devices and protection against electric shocks.
