1.1 AC input Two kinds of AC rated input voltage, the requirements of input voltage, current and frequency see table 1 (when testing, use NOMAL ±1% input voltage), when MINI input voltage and peak load, the power starts up.

Then, it will turn on again. The +5Vsb must be capable of being shorted indefinitely, but when the short is removed, the power supply shall recover automatically or by cycling the PS-ON#. 1.3.1 OVER POWER PROTECTION The power supply will be shutdown and latch off when total power over 110%~150% of rated DC output. Notes:5VSB will be auto-recovery when the fault removed. 1.3.2 OVER VOLTAGE PROTECTION Output Min Nom. Max.

PS-ON# is active-low, TTL-compatible signal that allows a motherboard to remotely control the power supply in conjunction with features such as soft on/off, wake-on-LAN, or wake-onmodem. When PS-ON# is pulled to TTL low, the power supply should turn on the four main DC output rails:+12VDC,+5VDC,+3.3VDC,-12VDC. When PS_ON# is pulled to TTL high or open circuited, the DC output rails should not deliver current and should be held at zero potential with respect to ground. PS_ON# has no effect on the +5VSB output, which is always enabled whenever the AC power is present. Vil,Input Low Voltage Min.

It provides a power source for circuits that must remain operational when the four main DC output rails are in a disabled state. Example uses include soft power control, wake-on-LAN, wake-on-modem, intrusion detection, or suspend stage activities. +5VSB is required for the implementation of PS_ON#. The +5VSB output should be capable of delivering a minimum of 2000 mA at +5V +/- 5% to external circuits. Overcurrent protection is required on the +5VSB output regardless of the output current ration. This ensures the power supply will not be damaged if external circuits draw more current than the supply can provide. 1.7 HI-POT 1000VAC 3S 10mA Min.
