Power Supply
CPWS152 is a 500-watt Power Factor Corrected (PFC) autoranging supply. It automatically
switches between the 115V range (90-132 VAC) and 230V range (180-264 VAC), depending
on the location. The input frequency is 47-63 Hz, single phase. At full load, the power supply
has a minimum efficiency of 65 percent.
When you connect AC power to the system, the computer is powered in its lowest “trickle”
power state (the 5V Standby output is On) and the Power LED glows yellow, though the fans
do not run. In this respect, the TDZ 2000 GT1 is always powered on.
An interlock switch turns off input voltage to the power supply when the side panel is
removed. A tab on the left end of the left side panel closes the switch when the panel is
correctly installed on the system.
The power supply contains no user- or field-serviceable parts. You must install a new power
supply if an internal component, such as the fan or interlock switch, is defective.
The following table details the DC output specifications for the power supply.

The following notes apply:
1. Maximum co5.0V and +3.3V power is 385 Watts
2. The 5V Stdby (Standby) output shall remain ON with the AC input power connected,
whether the power supply DC outputs are disabled (OFF) or enabled (ON) by the power-
up circuitry.
