VPI Traveler


The Traveler, and the Classic 1 now have an additional circuit board in them that does essentially what the SDS does...it creates a much better power source for the motor. There are no adjustments, but the tables have improved performance. Harry is always making his stuff better.

Is the circuit board an AC regenerator that also reduces the motor voltage after startup like the SDS?

I doubt that!

BS from VPI!
The SDS regenerates the AC to eliminate line noise. Then the resulting output voltage has a crystal calibrated oscillator with the frequency, that you set. to keep the the motor speed exact, compared to the supplied strobe. The SDS also generates a flattened sine wave that is reduced in amplitude, for reduced noise, after the motor starts.

Do you think a simple circuit board can do all that?

Harry is feeding you B.S.

That little circuit board is no SDS!
