3.8 Power Supply
4-28 VDC, app. 70mA at 18VDC. 18VDC PSU with 10m ready made cable is standard equipment.
When connecting any additional sensors, please note, that the supply voltage for the additional
sensors is lead via a reverse polarity protection diode from the weather station's PSU.
Caution: Some additional sensors (LUX-sensor, Rain detector;..) need at least 9 VDC for proper
operation!
CAUTION: Never connect two power sources (i.e. standard RS-232 cable with PSU and
network cable with PoE) at the same time to the MWS 55V!!
This will lead to shorts between the power sources and may damage your MWS 55V!!
Damages as a result of this are not covered by warranty!!

3.9 Heating device
For operation in winter a heating device is available as an option for MWS 55, MWS 10 and wind
and precipitaion sensors series 55.
The heating device operates at a power of 20W at 18VDC.
The heating device is switched on automatically when the internal temperature of the weather
station drops below 7°C. This happens at external temperatures between 1°C..5°C, depending on
the wind conditions.
This turn-on-threshold may be changed by commands via the interface (for details please contact us).
