Prime power
to the
system is
3
phase,
50160 Hz.
A.C.
input
voltage is selected
by the
customer
when
ordering
the rnachi:ae.
Minor
voltage
adjustment
can be
made in the
field
to
cope with local differences from
the
specified
voltage. Available
input
voltages are 21O,22O,
23O,
38O,
+OO,42O,44O,
460 and
480 v.

in
which close
voltage
regulation
is
not important.
These
include:
1. The
24
volt D.C.
regulator
which produces
the smooth
