Not in your country, but definitely in most of the rest of the world.Steve.
I though most of the rest of the world was 240V per leg. I don't know whether they are single or 3 phase.
Realistically, how many venues in the US can actually provide 3 phase power without a special request.Peter you never did answer my question. Is there anywhere in the USA where your products can be seen, touched, or purchased?
Domestic power here in the UK is 240 volts (or 230 sometimes). This is distributed as 415 volts three phase with only one phase and neutral being connected to each house.Industrial properties which need more power get connected to all three phases and neutral so that both 415v three phase and 240v single phase can be derived from the same incoming supply.Steve.
Thank you all for enlightening me. My requests for 3 phase power, mostly in large convention halls, has always been met with a polite "fill out this form", and a "maybe, check tomorrow." On the other hand I have access to any type power at the facilities I work in for the day job, so I'm not saying 3 phase is rare, I just didn't expect it to be common for entertainment purposes. Thinking back, I suppose that's pretty short sighted (duh).The other half of my question is simplistic. The PKN Audio site shows a number of 1U amplifiers with very respectable specifications, all capable of running from voltages as low as 90V. It would be nice to know if these products are available in the USA, and if so where can they be seen.
Here the power is distributed to each house (apartment) as 3 phase 415V. There are few 3 phase wall outlets in the kitchen usualy and in the living room if you need to heat it on electricity. The rest is 240V, one leg of that 415V. This is divided trough out the house more or less evenly to each leg. Meaning some of the lights are on one leg, the rest on another. Same for the wall outlets. So it is not unusual in the same room to have outlets each out of different leg.All 3 phase outlets are 5 wire (3 hot, 1 neutral, 1 ground). Each 240v outlet is 3 wire (1 hot, 1 neutral, 1 ground).
I have often thought about the advantages of using 3 phase power to supply an amplifier – much easier to make a solid DC supply with a 3 phase bridge rectifier.
There are even advantages for low power amplifiers, but the universe of customers with access to 3 phase power is a small fraction of the total market for power amps. JR
