New Critical Problem with ‘Smart’ Meters: The Switching-Power Mode Supply (SPMS)

Just When You Thought It Was Safe to Opt-Out
Ironically, now that PG&E is offering to disable the wireless RF function (for a hefty price) in their smart meters, we find that there’s an another extremely critical problem with the meters.
Just when you thought you had mastered all the esoteric acronyms, and all the problems with ‘smart’ meters, here’s one more: Switching-Mode Power Supply or SMPS. This new element in the ‘smart’ meter controversy deserves immediate full official and public attention.
In our on-going investigation into why so-called ‘smart’ meters being installed by PG&E against rising public opposition are causing so many people to be sick, and so many problems with other electric and electronic equipment, we have been fortunate to obtain the advice of electrical engineers.
On examination of typical meters, including ABB, GE, and Landis Gyr, they report that, in addition to its RF transmitter, each wireless digital meter also has a component called the ‘switching-mode power supply’ (SMPS) – switching power supply for short. Its function is to ‘step down’ the 240v alternating current (AC) coming in from the utility pole power lines to the 2 to 10 volts of direct current (DC) required to run the meter’s digital electronics which record the electricity usage data."
