Installation
Sorensen DCS Series 3kW Supplies
2.4.3 Ventilation
The DCS system supply is fan-cooled, so it requires space on the sides for the ventilation inlets
and space at the rear for the ventilation exhaust. The following temperature ranges apply for the
best results when operating or storing the unit.
Operating Ambient Temperature
0 to 50°C no derating. From 50 to 70°C, derate 2% per °C
Storage Temperature Range
-55 to +85° C
