[Moon] Blower relay

[Jerry Kleker]

Hi Oene,

Have you tried putting a diode in series with one of the leads....
then shorting the diode (with the relay) for high speed?

  Hello All,

  Maybe a bit off topic, but think surely one can help me with this.
  I have a blower which runs at 150V AC for cooling the GS35b 
  but want to let it run at normal 230V AC during transmit periods.
  I already tried a conventional relay to switch the motor's both 
  wires between the two voltages, but that leads to lots of sparks and
  black contacts in the relay.
  So I am in need of a circuit schematics of a solid state relais that
  can switch between each voltage.

  Thanks in advance 

  73 Oene
