Anti-Condensation Heater (Diagram 478850)
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, two 30 W
anti-condensation heaters automatically switch on
and prevent condensation from arising.

RS485 Interface (Diagram 478850)
All units are supplied with connections for RS232.
The RS485 Interface option provides a galvanic isolated
RS485 connection and allows for multi-point connection.
