Engineering Data

I Definition of Inrush Current, Start up Time and Hold Time

I Overload Protction

The Power supply is provided with an overload protec tion function

that protect the load and the power sup ply from possible damage by

over current. When the output current rises above between 105 to

130% of the rated current, the protection function is triggered,

decreasing the output voltage. When output current falls within the

rated range, the overload protection function is automatically cleared.

I De-rating Curve

For UL and CSA the maximum temperature is 50% (with derating of

2%/°C from 40 °C to 50 °C, only for 40 A model)

I Overvoltage Protction

(except for 40 A model)

If output voltage exceed the rated voltage more than 20% (50% at

maximum) by some reason, then the output voltage will be turned

OFF automatically for safety. To restart the S8PE, turn OFF the input

voltage, wait for about one minute, then apply the input power again.
