Just installed a "buck boost transformer", first
time I ever dealt with one. It worked! Or so far,
I'm getting the right voltage, haven't run it
with a load though.
I know the theory behind a transformer, but this
is just some really weird circuitry. I know it's
all math, but I just can't wrap my mind around
what's happening in there! Bought them from my
local electrical salvage supplier. He dug them
out of the bone pile, showed me an application
chart and a wiring diagram. Told me "Don't over
think this, just do it and it will work!"
We just bought a new CNC band saw. It has an
inverter drive, and the recommended voltage was
208 to 240 volt. The voltage in the shop runs
high, around 249 to 251. They (the dealer) didn't
want to start it up with that high voltage, but I
talked them into it, everything else in the shop
has run just fine for years, including another
one of their saws with the same drive.
Well, three days later the inverter drive failed.
Of coarse they blamed the high voltage, agreed to
warranty it but we had to get the voltage down.
So, stepping out in faith, wired them up to the saw, got the
volts down from 250v to 226v, just like the chart
said it would!
Wondering though, does anyone else have above
average voltage in their shop? Have any problems
with it? The electric company says it's normal,
they won't do anything about it... Electricians
I've talked to say don't worry about it...
New equipment dealers don't like it. Want to see
it within their specs for warranty purposes...
