Anti-Condensation Heater (Diagram 478801)
In areas with high relative humidity, temperature drops cause formation of dew inside the enclosure of
the GPU. On a long-term basis this can affect components such as relays, switchgears and printed
circuit boards (PCBs). Dew formation can however, be avoided by installation of heating elements in
the GPU.
During operation the waste heat from the circuits prevents dew from arising. In stand-by mode where
the internal losses are insignificant, one 30 W anti-condensation heater automatically switches on and
prevents condensation from arising.
