Powering

WMT700 is designed to operate with the same supply voltages as WS425
and no connection changes are necessary. The power consumption
depends on the selected heating options. WMT700 with Heated
Transducers can be used to replace similar WS425 models. When
upgrading from WS425 to WMT700 with Heated Transducers and Arms,
more capacity is required from the power supply unit.

For information on power supply requirements of each WMT700 product
type, see Table 9 below.

For more information on powering, see Vaisala WINDCAP
