Product Specification

2.3.2 Definition

The ripple voltage of the outputs shall be measured at the pins of the output connector

when terminated in the load impedance specified in figure 1. Ripple and noise are measured

at the connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic capacitor to simulate

system loading.Ripple shall be measured under any condition of line voltage,output load,line

frequency,operation temperature.

2.4 Overshoot

Any overshoot at turn on or turn off shall be less 10% of the nominal voltage value, all outputs shall be within

the regulation limit of section 2.0 before issuing the power good signal of section 5.0.

2.5 Efficiency

Power supply typical efficiency is 80% under full Load at nominal input voltage of 115VAC or 230VAC.

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.

3.1 Over-power protection

The power supply will be shutdown and latch off when output power is 110%~160%.

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.
