Any idea how I can cheaply stabilise a 230v AC supply. I have a 230v AC feed
to a metal detector that fluctuates by a couple of volts and I'm not sure if
this is causing it to keep tripping on metal detect. Any ideas?
Depends on your definition of cheap. ISOreg or similar transformers
are available with constant outputs. I personally use a 480 3ph unit
for a control power application.
I also have 3 metal detectors (Gorring Kerr), 2 units perform
flawlessly. The third installation, regardless of which equipment is
installed there, has problems with random detections, thousands of
them. If you are interested, I would be happy to continue this
discussion in greater detail.
A stable power supply is an important criteria, but in theory only
step changes in voltage would affect a metal detector. Example:
voltage dip from an A/C compressor cycling.
A two volt variation is a .87% regulation which is quite good. The detector
may have an internal DC regulator with input regulation to negate the effect
of the 2 volt variation in the 230 volt line. Anyway, the line voltage
variation is NOT the problem unless there are large spikes unaccounted for.
