Thanks Mike,
My DC current is only powering two things: the Sensor itself, and an Atlas Oil Pump.
When the sensor trips and the pump starts working, it stays at a constant speed, since nothing else is drawing current.
My concern is that somehow, an unregulated transformer would burn-out the sensor switch.
Perhaps the sensor company recommends regulated power supplies because the motion sensor is really built to trigger a loud burglar alarm of some type, and they are worried that the dropping of the current created by the sensor itself will cause the downstream current to the alarm to drop below the minimum voltage to operate it.
Assuming there isn't a burn-out issue with the sensor, I am fine. I guess we will see if it still works in a month or two. :-)
Thanks again,
Mannyrock
