5.1 Max. ambient temperatures
The ISpac isolators can be used over a wide temperature range. Depending on the isolator
version and installation method different maximum ambient temperatures may result.

5.2 Power dissipation
Data sheets are describing the maximum power dissipation in standard operation (output
20 mA; power supply 24 V DC; load = 250
Ω
). In practice not all isolators are working with
full load. Therefore engineering is done typically with an average power dissipation of 70 %
(P
70%
).
Type max. power dissipation 70 % power dissipation
