with
a
choice
of
enter
voltage
taps.
The
transformer
primary
windings
are
shipped
wired
for
117vac
applications.
A
factory
provided
switch
alternates
between
230vac
and
117vac
applications.
The
output
voltage
is
delivered
to
the
610+2
Board(in
KSU1,
Base
Board
in
KSU2)
for
voltage
regulation.
All
system
operation
and
logic
voltages
are
produced
at
these
boards.
Two
fuses
are
provided
on
the
power
supply
board;
one
for
ac
enter
over
‐
voltage
protection
and
one
for
DC
output
over
‐
current
protection.
A
main
power
switch
is
accessible
on
the
side
of
each
KSU.
In
the
event
battery
backup
operation
is
desired
the
KSU
power

can
be
connected
with
an
external
(ancillary)
UPS
(Uninterruptible
Power
Supply).
It
is
the
responsibility
of
the
