Powersoft amps running on 220v/240v
« on: May 25, 2015, 11:56:52 AM »

Hello all: I currently have (4) powersoft amps that I use for my rig (2) k20(subs) ../ (1) k10 (mids) .. / (1) k2 (highs) I have been operating these amps on 110v/120v, a friend told me that I could run these on 220v/240v .. is this true and if so what are the advantages?  Thanks

Lower current draw is the advantage.  Powersoft says they use universal PSU, so anything from 115v-230v +/-10%.

What power inlet connector is on your K20 and K10?

As Tim says-current draw.

But why is that important?

With less current draw, there is less voltage loss over cables.

This includes not only the power cable of the device-but also the power distro system.

With less loss-there is more voltage (power) available to the amplifier.

There is no downside to running at 240V-if you have the connections available.

And to add, there is only x amount of power available from the wall/plug.

With a higher voltage-you can get more power out of the device (assuming it is capable)-because there is more power available at the input.

So it is possible to get higher voltage peaks for a longer period of time.

That is a good thing.

I did also look on the powersoft site, I had seen that the power cable which I believe is rated somewhere around 45 amps has the 3 prongs for line, neutral & ground.

That is the connector-not the power cable.

I don't know what size cable is included with the unit-but 45Amps would be around a 5 ga cable-which is a pretty good sized cable.

I doubt the cable is that large-but could be wrong.

It is a large cable, I will try to contact Powersoft to find out for sure before I do anything.. Thank you Ivan.

Why would the size of the cable matter to you?

I would assume that it is already properly sized by the manufacturer.

At 240V, the current draw is half-not double-so that is not a problem.

^^ That's what I was thinking!
And with power being I^2 x R, the power dissipated by the cable due to its resistance will be a quarter of what it was on 110v.

If you're running power distro, powering the amps at 240 volts gives you a few advantages.

1. You can use smaller gauge power cables to get the same result. 
2. If you are supplying power to your amp rack from more than one phase of the distro, you can use only 2 legs and a ground. There's no need for the neutral conductor.
3. No neutral connector means your amps won't fry if the neutral line gets disconnected for some reason.

The disadvantage of running at 240v is that you now have to find 240v.  In some venues, where only regular outlets are available, it could be challenging.  However, since the amps can run at a full range of voltage, all you need is a set of secondary power cords to plug the amps into regular outlets.  Piece of cake.
