Functions
Start-up Time
The time required for the output voltage to reach 90% of its final steady state value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its final steady state value.
Hold-up Time
Hold-up Time is the time between removal of input AC voltage, and the subsequently falling output to reach 90% of its steady state
value.

Dynamic Response
The power supply output voltage will remain within ±10% of its
steady state value, when subjected to a dynamic load 50 to 100%
of its rated current.
50 to 100% Load
their maximum power limit, the protection will be activated and
the power supply will latch off.
Over Temperature Protection
As mentioned above, the power supply also has Over
Temperature Protection (OTP). This is activated when the
overload condition persists for an extended duration and the
output current is below the overload trigger point but >100% load.
In the event of a higher operating temperature condition at 100%
load, the power supply will run into OTP when the surrounding air
temperature is higher than the operating temperature. When
activated, the output voltage will go into latch mode until the input
voltage is removed; then, reapplied, and the surrounding air
temperature drops to its normal operating temperature.
Power Good
Inrush Current
Inrush current is the peak, instantaneous, input current measured
and, occurs when the input voltage is first applied. For AC input
voltages, the maximum peak value of inrush current will occur
during the first half cycle of the applied AC voltage. This peak
value decreases exponentially during subsequent cycles of AC
voltage.
The Power Good signal prevents a computer from attempting to
operate on improper voltages and damaging itself by alerting it to
improper power supply. The ATX specification defines the PowerGood signal as a +5 volt (V) signal generated in the power supply
when it has passed its internal self-tests and the outputs have
stabilized. This normally takes between 0.1 and 0.5 seconds after
the power supply is switched on. The signal is then sent to the
motherboard, where it is received by the processor timer chip that
controls the reset line to the processor. When plug in AC power
cord, +5Vsb will start first, then Remote On/Off will be pulled low
by computer, +12V1/+12V2/+5V/+3.3V will power on and Power
good signal will pull high after 100ms~500ms. After input AC is
removed, Power Good signal changes to TTL Low at least 1
millisecond before any output falls out of regulation range.

Overvoltage Protection
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 4 under “Protections”. Power
supply will latch off, and require removal/re-application of input
AC voltage in order to restart.
Short Circuit Protection
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied to
any of the outputs, the power supply will latch off.
Overload & Over current Protections
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated before the output currents reach the
limits defined on Page 4. Once the power supply has reached
9
Remote On_Off/INHIBIT
Remote ON_OFF/INHIBIT can be used to enable or disable all
outputs, except for the +5 Volt Standby. This signal can be pulled
down to a low level of 0.3 volts, or shorted to DC-Return, in order
for the main output to be enabled; and, floated (no connection to
the signal), or pulled up to a value greater than or equal to 3 volts,
in order to disable the main output. When the main output is
disabled, the +5V Standby output will continue to operate.
