Power Supply

The power supply circuitry of the Emerald ICE incorporates a linear design AC transformer with a
choice of enter voltage taps. The transformer primary windings are shipped wired for 117vac appli-
cations. 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 cord can be connected with
an external (ancillary) UPS (Uninterruptible Power Supply). It is the responsibility of the installer to
match the battery requirements/UPS requirement to the specific needs of the equipment owner.
