3. Overshoot:
Any output overshoot at TURN-ON shall not exceeded 10% of nominal
voltage value. 4. Overload Protection:
All DC output are protected from short circuit condition. At full load
(per unit) 5. Conditions: 95/190 VAC input 6. Limit: when output power is between 110%~150% 7. Over Voltage Protection:
The AC must be reset to restart For +5V DC 8. Conditions: All operating 9. Limit: +5.5V ~ +7V
GENERAL SPECIFICATION: 1. Efficiency: 65% minimum at 115VAC, 300W output 2. Operation Temperature: 0°C to 50°C 3. Storage temperature: -25°C to 85°C 4. Humidity:
Operating: 20% To 80% RH , Storage: 10% To 90% RH 5. Hold Up Time:
All output voltages will stay within regulation for at least 16.6
milliseconds after an AC line voltage failure is detected at nominal
line (115 VAC or 230 VAC under full load condition.) 6. Turn on Delay:
All outputs are within regulation limits in 100 milliseconds. 7. Reset After Shutdown (When Protection Circuit Is Activated):
If the power supply latches into a shut down state due to fault
condition on its output, the power supply shall return to normal
operation only after the fault has been removed and the PS-ON has been
cycled OFF/ON with a minimum OFF time of 1 second. 8. Power Good Signal Control Definitions:
PS/ON is an active low signal that turns on all of the main power
rails including 3.3V, 5V, -5V,12V and -12V power rails. When this
signal is held high by the PC board or left open circuited, outputs of
the power rails should not delivered current and should be held at a
zero potential with respect to ground. Power should be delivered to
the rails only if the PS-ON signal is held at ground potential. This
signal should be held at +5VDC by a pull¡Vup resistor internal to the
power supply.
5VSB is a standby voltage that may be used to power circuits that
require power input during the powered-down state of the power rails.
The 5VSB pin should deliver 5V¡Ó5% at a minimum of 10mA maximum from
this pin unless a power supply with higher current capabilities is
clearly specified. This power may be used to operate circuits such as
soft power control for future implementation. It is recommended that
the5VSB line be capable of delivering 720mA.This increased current
will be needed for future implementation with features such as "wake
on LAN"
PW-OK is a power good signal and should be asserted high by the power
supply to indicate that the +5VDC and +3.3VDC output are above the
under voltage thresholds of the power supply. When this signal is
asserted high, there should be sufficient main energy stored by the
converted to guarantee continuous power operation within
specification. Conversely, when either the +5VDC or the +3.3VDC output
voltage falls below the voltage threshold, or when main power has been
removed for a time sufficiently long so that power supply operation is
no longer guaranteed, PW-OK should be asserted to low state. Figure1
represents the timing characteristics of the PW-OK, PS On, and germane
power rails signals. 9. Power Good Single:
This signal is logical and of the +5V output voltage sense signal and
the DC input voltage sense signal. The power good signal is also TTL
compatible high level for normal operation or low level for fault
condition. The DC fail signal cause Power Good to go to low level at
least 1 millisecond before any output fall below the regulation
limits. The operation point used as a reference for measuring the 1
millisecond is normal operation at minimum and maximum load.
Although there is no
requirement to meet specific timing parameters, the following signal
timing are recommend.
Motherboards should be designed so the signals timing recommended
above are used. Using these recommendations will help drive the
industry to an acceptable standard. If timing other than these are
implemented or required, this information should be clearly specified. 11. Withstand Voltage (Isolation) ( HI- POT):
2121VDC, for one minute between each input AC line and the grounding
conductor. 4242VDC, for one minute between each input AC line
secondary low voltage outputs and shields.
All isolation transformers will have been tested prior to assembly
into a power supply unit.
Any such transformers without a grounded shield will be test to 3750
Vrms 50Hz. 12. Cooling: The air forced cooling.
