Product Specification

2.5 Efficiency

Power supply efficiency typical 80% at normal AC main voltage and full load on all outputs.

2.6 Remote on/off control

When the logic level "PS-ON" is low, the DC outputs are to be enabled.

When the logic level is high or open collector, the DC outputs are to be disabled.

3. PROTECTION

3.1 Over-power protection

The power supply will be shutdown and latch off when output power over 110% ~ 150% of

rated DC output.

3.2 Over voltage protection

The over voltage sense circuitry and reference shall reside in packages that are separate and distinct

from the regulator control circuity and reference.No single point fault shall be able to cause a sustained

over voltage condition on any or all outputs.The supply shall provide latch-mode over voltage protection

as defined in Table.

3.3 Short circuit

An output short circuit is defined as any output impedance of less than 0.1 ohms.The power supply

shall shut down and latch off for shorting the +3.3 VDC,+5 VDC,or+12 VDC rails to return or any

other rail. Shorts between main output rails and +5VSB shall not cause any damage to the power

supply. The power supply shall either shut down and latch off or fold back for shorting the negative

rails.+5VSB must be capable of being shorted indefinitely,but when the short is removed,the power

supply shall recover automatically or by cycling PS_ON#.The power supply shall be capable of

withstanding a continuous short-circuit to the output without damage or overstress to the unit

3.4 No load operation

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.
