 Over Load Protection

The Power Supply is provided with an overload protection (OLP/OCP) function which protects the power supply

from possible damage by over current. Additionally power supply also has over temperature protection (OTP) in

case the over load condition persists for a longer duration and is below the overload trigger point but > 100% load.

supply reaches max power limit and will run 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 also has a short circuit protection which is in line with the overload protection and activates

whenever there is a short across the output voltage, output goes in bouncing mode and remains until the fault is

removed.

 Over Temperature Protection

Additionally power supply also has over temperature protection (OTP) as mentioned above this OTP comes into

picture when the over load condition persists for a longer duration and the output current level is below the overload

trigger point but > 100% load.

Also in the event of a higher ambient operating condition with 100% load the power supply will run into OTP when

the Ambient temperature is > 55°C. The protection is self recoverable when activated output voltage bounces until

the operating ambient temperature of the power supply is reduced or the power supply is used within its power

derating curve.
