The +5Vsb is on whenever the AC power is present.

Note: The measurements should be made by crossing a 47uf/ electrolytic and a 0.1uf ceramic disk

capacitors at each output with measuring bandwidth from DC to 20 mhz. If ambient temperature is

under 20 C or over 30 C, the AC input should be nominal input.

The power supply outputs shall be enabled with an active-low TTL signal.

When TTL signal is low, the DC outputs are to be enabled.

When TTL signal is high or open circuited, the DC outputs are to be disabled.

Electronic means or a mechanical switch may activate the TTL signal.

After the TTL signal is active high, must wait for 3 seconds before active low again.

voltage falls below the regulation limits during PS-ON signal pull high.

2-13. Power Fail Signal (T6)

When the DC outputs (+5V, +12V, +3.3V) have over voltage condition,

the power supply shall provide latch mode over voltage protection.

3-1. Over Voltage Protection

A short circuit placed to ground shall cause no damage or power supply shall be shutdown.

(The contact resistance is 0.05 ohm when the outputs short circuit.)

3-2. Short Circuit Protection

When the power supply latches into shutdown condition due to a fault on an+5V,+3.3V,+12V,

output (OVP, UVP,OCP)and OTP, the protection shall reset after the fault has been removed,

use remote on/off control or recycle the AC power again for a typical of 5 seconds.

3-3. Protection Reset

Any output overshoot at turn on shall be less than 15% of the nominal output value

(with resistive load) as described in sec. 2.1.
