Thank you
You may want to do a little more research on this subject before you make your purchase. PWM's are best used to limit current. You are not going to find that magical resonating frequency, no matter what any publication says. No one has yet to recreate these claims. If they have, then I challenge them to submit physical proof for peer review.
