PERFORMANCE
2.2 Efficiency
The power supply is a minimum of 72% efficient under typical load. The “Energy Star”
efficiency of the power supply is a minimum of 50% when the AC input power is 60W.
2.3 Remote ON/OFF control
The power supply DC outputs (with the exception of +5 VSB which is always available)
are enabled with an active-low, TTL-compatible signal (“PS-ON”), When PS-ON is
pulled to TTL low, the DC outputs are enabled. When PS-ON is pulled to TTL high or
open-circuited, the DC outputs are disabled. PS-ON may be active by either electronic
means or a mechanical switch.
2.4 Overshoot at TURN-ON/TURN-OFF
The output voltage overshoot upon the application or removal of the input voltage is
less than 10%.
2.5 Hold-up Time
The power supply will maintain output regulation despite a loss of a minimum of 16 ms
while under full load. Test to be performed at nominal input voltage.
2.6 Power Good Signal
A “power good” signal is asserted by the supply to indicate that the +5VDC output is
within regulation limits.
Power Good Signal Characteristics
Signal Type Open collector TTL compatible
Logic level low <0.8V while sinking 5mA
Logic level high >2.4V while sourcing 500uA
High state impedance 1K (from output to common)
POK delay 100-500ms
Power fall warning time 1ms minimum
3. Protection
3.1 Over Voltage Protection
The power supply prods latch-mode over-voltage protection as defined below:
Nominal output voltage Trigger voltage
+12V 13.4-15.6V
+5V 5.74-7.0V
+3.3V 3.76-4.3V

3.2 Short Circuit Protection
A short circuit on any DC output will cause the power to latch. The power supply will
withstand a continuous short circuit to the output without damage or overseers to the
unit. The +5VSB can be shorted indefinitely and will recover automatically when the
short is removed.
3.3 No Load Operation
No hazardous conditions or damage to the supply will occur with all of the DC output
connectors disconnected from the load.
3.4 Over Power Protection(OPP)
The power supply shall go shutdown when the total output load is over 110-160% of
rating.
3.5 Over Current Protection
Overload currents applied to +12V1&+12V2 will cause the output to trip before reaching
or exceeding 240 VA. For testing purposes, the overload currents should be ramped
at a minimum rate of 10 A/s starting from full load.
4. Physical Environment
4.1 Operating Conditions
The power supply shall be capable of continuous operation and meet all electrical
specification without need for adjustment when subjected to the following
environ-mental conditions:

4.2 Shocks & Vibration
The power supply will withstand the following imposed conditions without experiencing
non-recoverable failure or deviation form specified output characteristics.
Storage -40G, 11mSec. half-sine wave pulse in both directions on three mutually
perpendicular axes. Operating -10G, 11mSec. half-sine wave pulse in both directions
on three mutually perpendicular axes. Vibration Operation-Sine wave excited, 0.25G
maximum acceleration, 10-250 Hz, swept at one octave/mine. Fifteen-minaret dwell at
all frequencies at which the device under test experience excursions two times large
than non-resonant excursions.

• Attach the power cord to the power supply
• Connect the power cord to a power
• Confirm the power supply is on
