The serial wind transmitter WAC155 transmitter accepts 9 ... 31.5 VDC input power. Typical average power consumption is 120 mW (with WA15 series sensors and powersave mode activated).

The power line is protected against incorrect polarity and overvoltage transients caused by nearby lightning strikes. Transient protection is accomplished with discharge tubes, VDRs, and transient zener diodes.

CAUTION If you have the revision B of the board (PCB210450B), the maximum operating voltage is 15.5 V instead of 31.5 V. The component board differs in size and outlook. See Service connector and jumper settings.
