Isolation transformer benefits:
superior conducted EMI suppression
isolated ground so you can safely use a Variac.
Stiff voltage regulator
I paid $270 total with shipping and tax for mine.
TOPAZ ULTRA 91002-22 2.4 KVA 60 Hz...
In grad school I had a 15 -25 kVA transformer I ran a MicroVAX II and a couple of terminals through under a work table. I had to move it away from the monitors it put out such a big field. It was left over from a Phoenix minicomputer system. The only power conditioner superior to a ferroressonant isolation transformer is a rotary motor-generator with a large flywheel.
The isolated ground aspect is most important for a ham shack or lab. It provides a ground which is isolated from the voltage so yjr only potential is between the two leads. On Wednesday, June 21, 2023 at 04:17:48 PM CDT, jim conrad <conr2286@...> wrote:
Hmm... perhaps I'm missing something here.? ?
While I have a whole-house protector in the service panel, all I use in addition at my bench is an off-the-shelf consumer device for computer/media equipment.? It's a reasonably nice one (4000 Joules) but very mundane.
