Switch Mode Power Supply DRP024V060W1BA
9/13 Rev: 00,
1/10/2011
Overvoltage protection
The Power Supply has an overvoltage protection (OVP) and is activated when the power supply
feedback circuit fails. The output voltage will not be > 35V under any Line/Load and operating
ambient temperature.
The Power Supply does not shut down but goes into Hiccup mode (Auto-Recovery). The output
voltage will recover back to 24VDC once the fault 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 below for the Inrush current in a typical Power Supply.
Start-up Time,
Start-up time is measured from the point AC input is applied to the point output voltage reaches
within 90% of its set value. See below for a typical start-up time characteristic.
Rise Time,
Rise time is measured from the point output voltage rises from 10% to 90% of its set value. See
below for a typical rise time measurement.
