I'm looking for information on the DXE-PS-3B antenna relay control circuit
current draw.  (There is no info published in the manual for the product.)
There are at least 11 custom relays in this unit.

   - The current draw for each individual relay coil
   - The maximum possible current draw for the entire PS-3B

My application uses 9 of the PS-3B units, and I'm trying to design the
12Vdc power supply system, including fusing.
