Hi,
I'm considering purchasing a fairly high capacity battery for indoor use as a pure DC voltage source. The purpose would be to compare the effects of an unadulterated voltage source to the noise generated by SMPS / mains AC. A 12v lead acid battery comes to mind but I am unsure about it's safety and efficacy for bench use.
1) Which chemistries are ideal for this application?
2) Which voltage / current regulators are available that are free of an AC component or as little as possible?
3) What other means do engineers use to produce a pure DC source for experimenting?
4) Any other considerations to take into account?
Regards,
Mark
