AC power bench supply for home

Hi,

Generally: you say 1500 dollars (US?) but don´t give any specification. Output voltage range, voltage resolution, max current, frequency, waveform, distortion..but also input voltage, size, ...

1) current limiter for AC is not that simple ... and sometimes it´s not what you want.
* When the current limiter is fast then it just cut´s off the to of the sine. High distortion. And the risk for remaining DC - which may be counterproductive on connected inductors.
* Doing a "slow" current limiter by reducing sine amplitude ... ist rather difficult, does not work on short time overcurrent, thus does not give the same protection level. There might remain high current peaks.
* On some loads a current limiter is counterproductive at all. Like when a SMPS is connected as load: then the ovrcurrent makes the RMS voltage to drop (in either case) and thus the SMPS draws even more current .. so you get an avalange effect and will result in complete stall or hick up mode.

2) Safer: In which regrad?

3) "a bit more professional": In which regard? just the current limiter? I guess you want some features that the current solution does not provide. But you missed to tell us.

Safer generally speaking when operating with line voltages would be an isolation
transformer ?

What are the loads you are generally working with, Resistive, Inductive, types,
lighting, motor.....?
