 Over Voltage protection

The Power Supply is protected by Over voltage in the event that power supply feedback circuit fails the

output voltage will not be > 32V, +10% under any Line/Load and operating ambient conditions.

The unique feature about this over voltage protection (OVP) is that power supply doesn’t shut down but

goes Hicc-up mode (Auto recovery) which is 32V, +/-10%. The power supply output voltage will

recover back to 24Vdc once the fault condition is removed.

 Inrush Current, Start Up Time, Output Hold Up Time

Inrush Current,

Inrush current is the first surge current seen on the input side when AC input is applied to the power

supply. It is the first pulse captured; see a typical picture for the Inrush current as seen in the power

supply.

Start Up Time,

Start up time is measured from the point AC input is applied and the o/p voltage reaches within 90% of

its set value. See picture below for a typical start up time characteristic of a power supply.

Rise Time,

Rise time is the time needed for o/p voltage to rise from 10% of its set value to 90% of its set value.

See the picture below for a typical rise time measurement in a power supply.
