2.4 Input Current Harmonics
When the power supply is operated in 90-264Vac of Sec. 2.1, the input harmonic current drawn
on the power line shall not exceed the limits set by EN61000-3-2 class "D" standards. The power
supply shall incorporate universal power input with active power factor correction.
2.5 AC Line Dropout
An AC line dropout of 17mS or less shall not cause any tripping of control signals or protection
circuits. If the AC dropout lasts longer than 17mS the power supply should recover and meet
all turn on requirements. The power supply shall meet the regulation requirement over all rated
AC voltages, frequencies, and output loading conditions. Any dropout of the AC line shall not
cause damage to the power supply. An AC line dropout is defined as a drop in AC line to 0VAC
at any phase of the AC line for any length of time.
Attention:
1.This power supply's default setting is six +12V rail configuration
2.Turn the switch on for six +12V rails and off for single +12V rail
3.Please make sure to turn off the power supply before adjusting the switch
Note 1: Maximum continuous total DC output power should not exceed 1200 W.
Note 2: Single / Multiple rail(s) for +12V is adjustable by a switch. (Rail Merging)

3.2 DC Voltage Regulation, Ripple and Noise
The power supply output voltages must stay within the following voltage limits when operating
at steady state and dynamic loading conditions. All outputs are measured with reference to the
return remote sense (ReturnS) signal. The +5V,+3.3V, +12V, -12V and +5VSB outputs are
measure at the power supply connectors references to ReturnS. The +5V and +3.3V is measured
at its remote sense signal (+5VS, +3.3VS) located at the signal connector.
Ripple and Noise shall be measured using the following methods:
a) Measurements made differentially to eliminate common-mode noise
b) Ground lead length of oscilloscope probe shall be 0.25 inch.
c) Measurements made where the cable connectors attach to the load.
d) Outputs bypassed at the point of measurement with a parallel combination of
10uF tantalum capacitor in parallel with a 0.1uF ceramic capacitors.
e) Oscilloscope bandwidth of 0 Hz to 20MHz.
f) Measurements measured at locations where remote sense wires are connected.
g) Regulation tolerance shall include temperature change, warm up drift and dynamic load.

3.3 Timing Requirements
These are the timing requirements for the power assembly operation. The output voltages must rise
from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The +5V, +3.3V and +12V output
voltages should start to rise at about the same time. All outputs must rise monotonically. The +5V
output needs to be greater than the +3.3V output during any point of the voltage rise. The +5V output
must never be greater than the +3.3V output by more than 2.25V. Each output voltage shall reach
regulation within 50 mS (Tvout_on) of each other during turn on of the power supply. Each output
voltage shall fall out of regulation within 400 mS (Tvout_off) of each other during turn off. Figure 1
and figure 2 show the turn On and turn Off timing requirement. In Figure 2, the timing is shown with
both AC and PSON# controlling the On/Off of the power supply..

Signal Type
PSON# = High Power OFF
PSON# = Low Power ON
Table 13 - PWOK Signal Characteristic
3.4 Remote On/Off Control : PSON#
The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active
low signal that turns on the +5V, +3.3V, +12V and -12V power rails. When this signal is not
pulled low by the system, or left open, the outputs (except the +5VSB and V bias) turn off.
This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply.
3.5 Efficiency
The efficiency is specified at 50% and 20% loading conditions to help reduce system power
consumption at typical system loading conditions.
3.6 +5VSB (Standby)
The +5VSB output is always on (+5V Standby) when AC power is applied and power switch
is turned on.
The +5VSB line is capable of delivering at a maximum of 4A for PC board circuit to operate.

Protection circuits inside the power supply shall cause only the power supply's main outputs to
shutdown. If the power supply latches off due to a protection circuit tripping, either a AC cycle
OFF for 15 sec, or PSON# cycle HIGH for 1 sec must be able to restart the power supply.
4.1 Over Current Protection
This power supply shall have current limit to prevent the +5V, +3.3V, and +12V outputs from
exceeding the values shown in table 14. The current limit shall not trip under maximum
continuous load or peak loading as described in Table 5. The power supply shall latch off if the
current exceeds the limit. The latch shall be cleared by toggling the PSON# signal or by cycling
the AC power. The power supply shall not be damaged from repeated power cycling in this
condition. The -12V and +5VSB outputs shall be shorted circuit protected so that no damage
can occur to the power supply.
4.2 Over Voltage Protection
The power supply shall shut down in a latch off mode when the output voltage exceeds the
over voltage limit shown in Table 4.
4.3 Short Circuit Protection
The power supply shall shut down in a latch off mode when the output voltage is short circuit.
