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 applications. A factory provided switch alternates
between 230vac and 117vac applications. The output voltage is delivered to the
610+2 Board(in KSU3, Base Board in KSU4) 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.
