How can I protect my electronics from in-rush current after power is restored?

One of the main benefits of Zero Surge’s Series Mode Filter Technology is that it prevents the damaging initial wave of power that can occur during a power restore  event. A traditional surge protector cannot perform this task because its main component, the metal oxide varistor (MOV) does not react to changes in  current or to voltage below its set value (at minimum 330 volts).

Using the Dranetz HDPQ Xplorer, we show what happens during this event in our Tech Note below.
