We use 110-120V 50hz in Jamaica. The Alienbees are 50/60 so they work okay. But I want to use something cheaper like $50-$100 strobes for hair and stuff like that. These strobes are all only 60hz. Also! because i want to risk leaving it in my vehicle as i would not risk leaving the alienbees.
So if i use this Xantrex power pack with say this adorama head, would'nt i be pushing 60hz into it? As long as I dont use the strobe while the xantrex is plugged into the wall. |

Yes, using the inverter you would be putting 60 Hz into the strobe. 400 watts of inverter power should be enough to drive at least one of these; it's 150W*s with recycle time of 4 to 6 seconds. Working with the 4 seconds and assuming 50% efficiency, you'd need 150W*s/(4s*.50) = 75W. Add the modeling light at 60W, and you'll be drawing in the range of 135W.
All that said, since the strobe needs to convert AC to DC to charge its capacitors anyway, the 50Hz vs. 60 Hz will likely make no difference. I'd wager that they will run just fine on 50Hz. you could try that, but of course there's a risk that I'm wrong given that I didn't design the strobe... you could call the manufacturer to see what they have to say. |

I don't know the answer but.... I have a stack of 220-240V 50Hz stuff running thru a 1KWatt converter down to 110-120V but it cannot shift to the US 60Hz, so it's still 50Hz and the only issue is things like turntables that don't spin at the right speed :-(( Granted your going the other way....
[For the Gen Y forward crowd... Ask your grandparents what a turntable is and what those black things are about]
Freq converters are hideously expensive.... whereas voltage converts are reasonable even for the big heavy ones I have. |

I'm thinking using the xantrex inverter offline should be okay, but if i use the strobes while its plugged in and charging well I dont know. |
