HI Larry
I am sorry I misunderstood your query, What you need is a 12 V. coil
relay capable of handeling the DC fan current at 48 volts. I
usually go to grainger for these, 12 volt coil (DC) and contact
rating of a single pole single throw relay, or a two pole, single
throw and wire the contacts in series. Find the current rating of
the Fan and make sure the relay contact rating is greater than this.
