LA6NCA RADIO PAGE POWER EWd

This is a power supply for radio receiver Kw.E.a or Lw.E.a.
Input voltage is 12 Volt DC.





EWd is designed to operate Kw.Ea or Lw.Ea receivers in a vehicle with a 12 volt battery.





The power consumption of Kw.Ea and Lw.Ea is different. Therefore, this must be set on the Power.
Which receiver selected can be seen in the small window on the front.
