5.2 Electrical Specifications<br />
Power Requirements:<br />
U-bolt mounting to mast or pole with outer<br />
diameter from 1.25 in to 2.07 in<br />
DSP power 9 to 24 V, (9 to 16 V limit when<br />
using CS215-PWS or other SDI-12 sensors).<br />
Current consumption 200 mA no dew heater or<br />
SDI-12, 1 A with dew heater and SDI-12. The<br />
currents are lower at high supply voltages as<br />
the sensor uses SMPS technology. Hood<br />
heater 24 Vac or dc, 7 A.<br />
