Frequency (Waveform) Generator
Frequency (Waveform) Generator
(OP)
I am looking for a site (or manufacturer) with information on frequency generators. I am looking to simulate European (50Hz) waveforms for testing equipment. Anyone with any info on this topic would be helpful.

RE: Frequency (Waveform) Generator
I am uncertain what your question is.
Do you require power at 50 Hz or just a 50 Hz signal ?.
If its the first, then I take it at your location you do not have 50 Hz mains and that you have something else 60Hz/120V maybe ?.
If so then you have a few options.
1. Convert your mains supply to DC (12/24V) then have an suitable inverter convert it back to AC of the frequency you require.
2. Use a motor generator/rotary converter set to convert 60Hz to 50 Hz power
3. Buy a 50 Hz elctric generator
The size & type above, of course depends on your power requirements. Are you testing transistor radios or electric cookers!!. There is a big difference in power requirements.
It also depends on the voltage at your location.
If your question is this then see the following links:-

If your question is for a 50Hz low voltage/current signal then
1. Buy a signal/function generators to suit.
2. Buy an IC if you wish to make your own.

Ok then how about frequency converters some are not up to 5KVA but is there the possiblity of more than one unit at different locations. (or does this thing their testing require the full 5KVA !)
As for AC/AC converters try
http://www.calinst.com/summ/freq.html#im
(the first is 3-15KVA but there are smaller ones on this page)
http://www.majorpower.com/frequency/majorfc2000.html
http://www.50hz.com/
These guys let you specify your requirements and they provide. See:-
http://www.georator.com/html/page3.htm
http://www.powerquotes.com/detailmanf.asp?Link=www.calinst.com&VendorID=213
Refering to my previous post
MG sets
http://www.assoc-elec.com/motor_generator.htm
(Give them a call & see if they can accomodate you)
or a converter
http://www.behlman.com/acdc.htm
(Thers is a 1.2KVA 110->220 50 Hz unit. The KVA rating is smaller but is there the chance they could have one per workbench ?)
If a Generator is required
http://www.gohonda.com/generators/50cycle/
(The LA60E/50Hz for example is a 5 KW , 100% PF generator but single phase)
Check them out you never know.
