Power Supplies
The Eclipse may operate from either the AC or DC Power Supply or Power Cartridge. When power is
available from an external supply, the Eclipse, in the majority of cases, will always draw from the external
source rather than depleting the Power Cartridge. Connection to external power is indicated when the
External Power Present Indicator located on the Control Panel is illuminated.
AC Power Supply
The AC Power Supply is a universal input type, capable of accepting 100-240VAC, 50/60 Hz. It is
capable of delivering up to 200W of 28VDC output. The input cord requires a grounded receptacle.
Country specific cords may be used with the AC Power Supply, as the supply is equipped with a
universal input receptacle. When used in a medical care facility, international safety standards require
the use of hospital grade AC power cord with the Eclipse.
Figure 5: AC Power Supply
During periods of high load, an internal fan comes on to cool the AC Power Supply. Like the Eclipse, the
AC Power Supply should be located in a well-ventilated area.
Located near the output cord, there is a Green LED that is illuminated when the AC Power Supply is
supplying 28VDC power. When output voltage falls outside of this range, the LED will turn red. If the
LED is not illuminated, there is no input power available. In addition, the Power Supply contains
protection circuits for output over-current, input over-voltage, and internal over-temperature conditions. If
any of these conditions exist, output power will be interrupted and the red LED will illuminate. However,
these three conditions are self-resetting, such that output power will resume when protection circuits fall
back into acceptable operating ranges.
