ABSTRACT:
power source conversion device capable of eliminating low-frequency radiation consisting of electronic circuit is designed to convent the marketable 2-hole type socket power source into 3-hole type socket so as to restore the characteristics of original 3-hole type power source through human body or electronic appliance housing or referable zero potential point, wherein the third hole is substitutive ground point to develop the effect of electromagnetic screening device built in the electric appliances in general for achieving good grounding and eliminating electromagnetic radiation and effect of electric leakage on human body because of poor insulation or induction, and meantime, through the functions of automatically detecting LIFE and NULL and such lines as actuating, locking, safe and warning, an intelligent power source conversion device with overall functions is well combined.
