“Modwright doesn’t seem to offer any information on what sort of power regulation is incorporated”
Reach out to Dan at Modwright, he is a straight shooter. As far as extra expense to invest in a well-regarded power conditioner, I suggest you invest in high quality surge protection at main breaker panel. And then buy a non-current limiting passive power distributor like Furutech GTO-D3 NCF.
Consider installing EP’s 2050EE Surge and AC Waveform Correction & EP-2750 Ground Filter.
