I AM IN MEXICO NOT MINNEAPOLIS.
GET TO THE POINT
Arecyou saying Power Master TRC Franks brands use TVS, avalanche rectifiers? Gas tube discharge transient voltage control systems? If they do come forth and spit it out. "Such and such unit does indeed have TVS devices.
AUTOFORMERS ARE VOLTAGE CONTROL OR MODIFICATION DEVICES
AUTOFORMERS ARE NOT COMMONLY CALLED SURGE CONTROLS DEVICES.
Each does a specific and much needed job of protection.
But an autoformer can maintain 120.00 volts and if it has little or no transient voltage suppression capability it will allow both positive and negative voltage spikes to pass which eat transistors and integrated circuits for lunch. The HUGHS units I dug through with a stick looked like a small PC board supported three small MOVS and three small MOVS do not offer even a modicum of protection against severe power line disturbances. Aapliances
And if the voltage control device has nothing but a couple of MOVs then it is near worthless for severe transient voltage spikes Both positive and ngative oriented.
Clue me in
DO YOUR BRANDS HAVE TVS CIRCUITS? YES, OR NO?
