I have several switch mode supplies that are supposed to power a commercial inductive lamp, via coupling coil/socket, at 2MHz 300VAC. I do not have the lamps or coupler, but need to use the supplies for another purpose. However, they show no output on the CRO.
It is unlikely they are all bad. So I am wondering, is it conceivable the supplies would incorporate some kind of sensing circuit to prevent operation when not connected to the intended load?
If so, what would be the best bet for getting around this? IOW simulating the loading of the lamp and its coupler.
Thank you for any suggestions.
