What is the Amp Draw of the Voyager?

greetings,

I'm trying to size a UPS unit w/ automatic voltage regulation to protect my computer and recording equipment against power surges, spikes, brownouts, etc., including my precious Minimoog. Does anybody know the Voyager's power consumption? Do I need this in watts, or will amps suffice?

Thanks!

Simple math:

watts = voltage times current

Solve for current

current = watts divided by voltage

My Voyager SE has a label that says 40 watts, so with US 120VAC that is 0.333 amps.

This is only true on DC voltages. Its not that easy on AC. Just think of the sine shaped main line voltage and you know why there is a difference in the calculation for DC and AC.
Anyway, the figures are only a little lower then that 40 watts.

Ahh, so 40 watts is the maximum load a Voyager will demand?

Yes. That is the meaning of the label on the Voyager or any electric device.

This is only true on DC voltages. Its not that easy on AC. Just think of the sine shaped main line voltage and you know why there is a difference in the calculation for DC and AC.

Complex AC waveforms and three phase power use a different formula, but the simple equation works for sinusoidal AC waveforms and single phase power. It is standard convention in residential power distribution.

You can get a Furman RP-8 power conditioner from Musician's Friend for $49.95 US. Here's the link:

They have a 15 amp load and are very inexpensive. I have several of them and I haven't had any problems with them.
