least 87%/90%/87%.

1.6 STANDBY MODE

During measurement of the ”STANDBY MODE” condition, the main converter is off 
(PS_ON=High). +5Vsb converter is working and standby input power is measured.

1.7 ACTIVE POWER FACTOR CORRECTION (PFC):

2.0 OUTPUT:

NOTE:

1.The continuous maximum total output power shall not exceed 850W. 
+12V DC maximum output power shall not exceed 70A(840W). 
+3.3V and +5V DC maximum combined output power shall not exceed 100W. 
2.Maximum peak total DC output power should not exceed 935W. 
3.Peak power and current loading should be supported for a minimum of 1 second. 
4.+3.3V, +5V and +12V DC output voltage should be within Figure 1 cross loading range to 
meet regulation. 
5.Load regulation measuring the output voltage difference between 80plus 20% and 100% load. 
6.Ripple and Noise measuring with an oscilloscope with 20 MHz bandwidth in Figure 1 cross 
loading range. Output should be bypassed at the connector with a 0.1uF ceramic disk 
capacitor and a 10uF electrolytic capacitor to simulate system load. The length of ground wire 
on probe should not longer than 40mm, if a Non - differential type of scope was used. 

2.1 CROSS REGULATION

The +5V & +3.3V combined load and +12VDC load shall remain within the defined in section 
2.0 over cross load combinations shown Figure 1

2.2 HOLD-UP TIME: 16ms(minimum)

Test Condition: Full load. AC input 115V or 230V, 47Hz . 

2.3 LOAD TRANSIENT RESPONSE (STEP LOAD) 

Step load changes up to 60%(12V) and 30%(3.3V and 5V) of full load, while other loads 
remains constant within the rating. The load waveform shall be a square wave with the slope 
of the rise and fall at 1.0A/usec and the frequency shall be from 50Hz to 10kHz. The DC 
output voltage will stay within regulation of ±5% during the step load changes. 

2.4 OVERSHOOT 

Overshoot at turn on or turn off shall be less than 10% of the nominal output voltage. 

2.5 TIMING, HOUSEKEEPING AND CONTROL

A low active PS-ON (DC ON/OFF) input signal is equipped, which provide the interface 
ENABLE or to DISABLE the GROUP1 of DC output. This signal is electrically to interface 
with TTL,OPEN COLLECTOR and the HARD SWITCH.

コレクターとハードスイッチ

2.5.1 POWER GOOD SIGNAL: 

Signal Type: open collector +5DC, TTL compatible. 
Logic Level: <0.4V while sinking 4 mA. 
Logic Level High: between 2.4VDC and +5V output while sourcing 200 uA. 
Max Ripple/Noise: 400mV pk-pk. (no capacitor test)

3.0 OUTPUT PROTECTION 

3.1 TOTAL POWER PROTECTION: (OPP ) 
Total power 150% max with shut-down and latch off protection.

3.2 OVER VOLTAGE PROTECTION: (OVP)

3.3 SHORT CIRCUIT PROTECTION: (SCP) 

The short between any output of group 1 will shut down all group1. 
The short at group 2 will Shut down both group 1 and group 2.

3.4 OVER CURRENT PROTECTION: (OCP) 

Over current protection was designed to limit the current to operate within safe operating 
conditions. 
+3.3V, +5V and +12V rails latch off protection required with AC line or PS_ON reset. +5Vsb 
rail auto-restart upon removal of fault condition.

3.5 OVER TEMPERATURE PROTECTION: (OTP)

This power supply include an over-temperature protection sensor,which can trip and shut down the power supply at a preset temperature point. Such an overheated condition is typically the result of cooling fan failure or excessive maximum operation temperature.

3.6 NO-LOAD SITUATION

No damage or hazardous condition should occur with all the DC output connectors disconnected from the load. The power supply may latch into the shutdown state.

3.7 RESET AFTER SHUTDOWN

Whenever the power supply latches into shutdown state due to fault condition on its output, the power supply will return to normal operation only after the fault has been removed and the

PS_ON# has been pulled low again. If the power supply latches into shutdown state due to fault condition on 5Vsb, the power supply will return to normal operation only after the fault has been removed and the power switch(power cord) has been cycled off/on(plugged out/in) with A MINIMUM OFF TIME OF 3 SECONDS.

4.0 COOLING OF POWER SUPPL

A DC fan was equipped to cooling the power supply, the fan will blow air into power supply and exhaust through the vent holes in AC receptacle side. This fan is only for power supply internal cooling purpose, not for system cooling. Fan parameters:
