24V, 400W, DC/DC CONVERTER
15. ENVIRONMENT
Conformal coating yes all pc-boards are conformal coated
Operational temperature
*)
-40°C to +70°C (-40°F to 158°F) continuous operation, reduce output power
according Fig. 15-1 for input voltages below
100Vdc
+70°C to +85°C (185°F to 185°F) for maximal 10 minutes every hour
Storage temperature -40 to +85°C (-40°F to 185°F) for storage and transportation
Output de-rating 0.08A/V at +70°C or
0.16A/°C at 77Vdc
required for input voltage smaller than 100Vdc
in combination with ambient temperatures
above +60°C (140°F).
Derate linearly between 100Vdc and 77Vdc or
+60°C and +70°C, see Fig. 15-1.

II altitudes from 2000m to 6000m
Degree of pollution 2 IEC 62103, EN 50178, not conductive
LABS compatibility The unit does not release any silicone or other LABS-critical substances and is suitable for
use in paint shops.
Audible noise At load currents below 2A some audible noise will be emitted from the DC/DC converter
*) Operational temperature is the same as the ambient temperature and is defined as the air temperature 2cm below the unit.
**) Do not energize while condensation is present
***) Tested in combination with DIN-Rails according to EN 60715 with a height of 15mm and a thickness of 1.3mm and standard
orientation. Higher levels allowed when using the wall mounting bracket ZM2.WALL
