Hi Group,
It's been a long time since my last post. Hope everyone has been well.
We have a several AC power sources that can provide 230Vac/50Hz power.
Only one however provides true Euro power in that it provides 230VAc on
the line side. This unit only has around 6 amps of capacity. We need
to be able to provide at least 20amps.
We have 2 other units with higher current capacity, but the 230 Volts
can only be provided via 115V on L1 and L2 to ground. I have been told
by some, that using this power source is acceptable for emissions and
immunity testing. I'd like some feedback on that. I can justify it,
perhaps, for radiated emissions, radiated fields, ESD and perhaps
magnetic fields, but I am skeptical that this would be okay for AC mains
testing that apply immunity at various phase angles and also for EN
61000-3-2 and -3. Any comments?
Another question, we have tried using a 2:1 transformer to step up the
115, but we end up with about 60Volts of bleed over to the other line.
Is this typical of transformers? Anyway to prevent this?
Kind Regards,
