Overload Protection; Short Circuit Protection; Over Temperature Protection - Delta Electronics DRP024V060W1BA Manual

 Overload Protection
The Power Supply is provided with an overload protection (OLP) function which protects the power
supply from possible damage caused by excess current. The Power Supply also has an over
temperature protection (OTP) in case overload condition persists for an extended duration and is
below the overload trigger point but > 100% load.
Typically the overload current (I
power supply reaches max power limit. It will go into bouncing mode when the output reaches UVLO
(under voltage point). The output voltage will recover automatically when the overload condition is
removed.
 Short Circuit Protection
The Power Supply has a short circuit protection which is in line with the overload protection and
activates whenever there is a short across the output voltage. It will go into bouncing mode and
recovers automatically when the fault is removed.
 Over Temperature Protection
The Power Supply has an over temperature protection (OTP). This is activated when the overload
condition persists for an extended duration and the output current is below the overload trigger
point but >100% load.
In the event of a higher ambient operating condition at 100% load, the Power Supply will run into
OTP when the ambient temperature is > 55°C. When activated, the output voltage will go into
bouncing mode until the operating ambient temperature drops to 50°C or output capacity is reduced
as recommended in the graph.
